The thinking behind the suggested coax length is related to the wavelength of the CB frequencies used. At certain lengths of coax it can start to become an active radiator or transformer. 18ft has proven to be a good compromise to avoid some unwanted effects, though other lengths are possible, you have to know what you are doing. Keeping 18ft will make your installation and tuning effort more closely resemble the documented instructions, common experiences, and common remedies.

I did some measuring and if I run the cable like in the Project JK How To, 18' may just make it. If I run it down the roll bar, 18' will be plenty long.

For you guys that have run the cable down the roll bar, did you stay on the outside or snake it through inside the padding?

I was thinking of doing that for a clean looking install, but it looks like a project and a half to get it run through. LOL

It's not bad at all. It should just take you a few minutes!

Did you unzip any of the padding?
My main concern if getting the cable past the area where the sound bar attaches to the roll bar.

What took a long time was relocating the Sat antenna! I have it out on the hood now in front of the passenger. I tilted the hard top to run the coax aft to the starboard side. I unzipped the covers and it wasn't that bad. You sure learn a lot about your Jeep when taking it apart to install all this stuff! I want to push you into buying quality COAX. I bought the RG8X 18' with my 102" whip and the radio in a Bearcat Sideband with the mike gain pushed and the truckers tell me not to do ANYTHING! I have the antenna bent all the way over too! It sounds great they say. I havn't screwed with the SWRs yet either but I ran two RF ground straps from behind the ball mount to the chassis.

Good to know. I was debating raising the hardtop a few inches to make it easier to access the zippers on the covers. Did you have to remove the sound bar or were you able to work around it?


My other concern is the antenna hitting the garage door every time I pull in or out. Wondering if it will damage the antenna

I have this radio also. Referring to the portable Midland 75-822. When I first bought it, I also got a magnetic mount antenna. Since the Midland is not hard installed, the magnetic mount antenna did not ground well, so I couldn't get a good SWR across the channels. Now that I have a JKU, I'm deciding on an antenna. Probably a Firestix Firefly, hard mounted near the rear tire carrier area. Hope the SWR will be better with that set up.

I ran my antenna cable on the passenger (starboard) side (also) and had no issues. You don't have to remove the sound bar. All you have to do is open the padding up with a few zippers and some velcro. You need to untuck the roll bar cover at the bottom of the b-pillar to start of one of the zippers. Everything unzips very easy with the hard-top off. It's going to look so much better to have it tucked away vs zip tied. I would at least give the lift it 2" method a college try if you don't want to pull the top off.

I have the Firestik "Firefly" (denoted with a FL in the product code). It's the best off-road antenna I have found. It bends well so you don't have to add a spring at the bottom. Other models of Firestiks, and most other brands of antennas, are much stiffer. My 3' one is about 1" higher than the garage door and it works fine. After you tune your SWR I recommend putting some hair spray in the antennas plastic cap. It keeps it from popping off later. It's the same trick used for bicycle grips.

This is the 4' firefly on the cooltech ultra mount.

After reading this thread several times and the included links to other threads, plus members advice, I am ready to pull the trigger. Unless you all convince me otherwise I am going to go with the Midland 1001LWX because it is backlit and has NOAA weather radio.

I do have one last question. On FireStik's website, they recommend locating the antenna as close as possible to to the center of the vehicle. Does using the cooltech ultramount and having the antenna at the corner really make that much of a difference?

It only affects the radiation pattern. If you mount the antenna in the corner of the vehicle (passenger side) you will transmit a little further towards the driver's side front of the vehicle. If you mount it in the "center" of the vehicle , you will transmit equal distances in all directions. On a trail with limited distances between each vehicle it won't matter.

Thanks. Does it make any difference with radiation for highway use?

If mounted in the back you will transmit further towards the front of the vehicle but for all practical purposes it won't make a lot of difference.

What do you mean by that? If you're concerned about adverse health effects if a cb antenna, don't be. It emits radio waves that are not only completely harmless but also present all over the place whether or not you are emitting them yourself.

Signal radiation, i.e. did location have an appreciable effect on how the signal radiated from the antenna.

Oh, ok. From what i understand the most important factor for that (besides amplification gain) is how high your antenna is mounted. the more of the vehicle body it clears, the better. So i guess a mount in the center of the roof would technically be ideal, but kinda inconvenient.

^True. I am a newb when it comes to electronics. Since we have knowledgeable members I had been tossing out questions to help decide on the install.

ANTENNA LOCATION

There is an inverse relationship between where the antenna is placed and where it's projected.

Picture from> http://www.wilsonantenna.com/faq.php


I feel the top of the tail light is the best location within reason. It's main downfall is bending the cable with the gate. If that bend is made too tight it can ruin the cable and create higher SWR. Lots of people run the cool-tech without problems. We're not truckers so it really just needs to reach a mile in the woods and hills. The most important thing is grounding and tuning the SWR as far below 2 as possible.

IDEAL SET-UP
- As long of an antenna as possible. A two foot antenna may get 1.5 miles in the open. A 5' could see 10 miles. It's likely to be the biggest factor because of the FCC 4 watt limit. A 102" (8.5') quarter wave whip is the most powerful option. Because of them whipping around they are dangerous. Some places and clubs will not allow them.
- 1/3 of the antenna should be over the top of the roof. I would guess length, especially with a top wound antenna (like the FireFly), would trump this rule.
- High as possible
- Away from vertical surfaces, especially metal that create interference.
- In the open vs being sandwiched. Between the spare tire and jeep isn't ideal.
- centered

WEATHER CHANNEL FEATURE
I read an article where Firestik dissed the feature. Basically saying there wasn't enough stations. That made me think it wasn't that important. With smart phones its an almost worthless feature, but in retrospect it seem like something nice to have. If crap hit the fan I would suspect they would transmit over those stations. Maybe the emergency broadcast system would transmit on channel 9 also??

I was going to use the cooltech ultramount at the license plate bracket, but I was concerned about branches and stuff snagging the antenna.

The other option was to use the gate mount and have the antenna more protected.

Your thoughts?


PS: I did read the FireStik article on having the weatherband feature on a CB radio. At the time (1996) NOAA coverage was spotty and generally limited to metropolitan areas. The added cost wasn't worth the benefit. They added new info in 2006 stating NOAA coverage has inproved plus a link to find NOAA transmitters in your state.

Having weatherband wasn't the deciding factor, it was just a nice (to me) benefit.

I used the Teraflex mount that goes on the stock spare tire carrier. Even if you have a bumper mount carrier this mount will work. It is a bit off center but not by much. With the Cobra 75 and SWRs at 1.3 I was able to reach out about two miles with a clear signal and reception was great.

What do you guys recommend for a power source? Straight to the battery (I would forget to turn the CB off and run down the battery, LOL) or switched so there is only power when the key is in ACC or RUN?

I probably wouldn't recommend doing what i did because it's such a hack solution, but what i did was run the cb off the fuse to the power supply number 2 (not the one that works with the engine off).

A good (or better) way to do this would be to intercept and splice the wires going to the power plug. But that's not how i did it...

under the detachable lid to the fuse box, there is a diagram showing what each fuse is. Find one that only is on when the motor runs (eg the driver side power plug). Remove the fuse. With a multimeter, check which side of the fuse seat has voltage (with respect to body ground or to the negative terminal of the battery). You want to use the other side. Wrap the copper from the red power wire of the cb to one of the fuse leads. Insert the fuse back in, with the wire side on the voltage-less side (this ensues that if the fuse is tripped, eg in case of a surge, the cb is shut off automatically). Now carve a small groove for the CB cable in the edge of the fuse box and close the lid back. Wire the black cb power cable to the vehicle body (eg to any bolt that isn't painted). Boom. Now you have a cb that is fused (protected) and that only turns on when the engine is running.

Note that this is a pretty primitive way of doing it. There are definitely more elegant ways to go about this and i recommend those ways more. But this works for me.

Ps i installed the amplified speaker today and so far it works. It's so loud that at max volume, there is feedback when i key the mic even from inside the Jeep with the windows up (the speaker is under the hood). So yeah, it's loud

Works really well with a good antenna.

I'm just dragging my feet on my antenna install.

I have an SWR of less than 1.5 across channels with the Midland 75-822 running coax to a tire carrier mounted firestik (3ft). Wasnt difficult!

I was considering tapping into either the TIPM or the 12V outlet on the dash. I have heard this may cause noise on the radio versus going straight to the battery.

I think I'm just going to run mine straight to the battery. As long as it's really off when you turn the CB off I'm cool with that. I think I'd eventually run it off an SPOD but I'm not paying $450 just to power a $130 CB setup lol.

I just completed mounting an antenna on the top of the stock 3rd brake light, hence it is just over the tire and away from most body metal.

I used a 90 degree stainless bracket and drilled 2 holes into the back of the light. There is plenty of room in there for 1/4-20 bolts with the nuts and washers on the inside as long as you position the holes just inside the existing 2 screw holes. The center area is occupied by the light connector. Finding a suitable bracket is the hard part. I had a flat bracket from a previous truck I bent into shape, so it was predrilled. That is good 'cause stainless is tough stuff to drill.

The stock tire carrier is insulated from the chassis by the thick black paint and the tailgate paint, plus the large carrier bolts have plastic washers under them so as to not scrape the carrier's paint. I suspect this is done to prevent galvanic corrosion.

I used a dremel with a small grinder tip to grind off the paint on the carrier under one of the carrier bolts and removed the plastic washer and used a electrical grease designed to slow down corrosion of aluminum connections. With this done I verified the antenna bracket is electrically connected to the carrier and to the tailgate.

The stock tailgate to the body connection depends on hinge contact however. Not good enough for me so I used a section of braid and slipped it though the tailgate wire protection sleeving (along with my RG-8X coax that I ran down the passenger side under the carpet - My radio is under the passenger seat).

I crimped/soldered ring terminals for #10 studs on both ends of the braid. Connected 1 ring terminal on the exposed hinge stop (body side) bracket stud using the existing nut.

I drilled a small hole into the tailgate under the tailgate wire harness area.

TIP: To remove the tailgate plastic cover press down on the top edge of the cover to unhook the top edge, then pull straight out the bottom, or pull out the bottom and hinge it upward to prevent breaking the small top tabs.

I used a short stainless sheet metal screw to connect the other end of the braid into that new hole. Connection verified good with an ohmmeter.

There is a 1" oval hole in that tailgate wire channel 12" or less from the hinge. I ran my coax into that and out the blank rubber plug that is on the outside, hinge side, of the carrier (after drilling a hole in the plug first).

I routed the coax into the center of the carrier and up out the top back and used a nylon P-clamp on one of the lower tail light screws as a coax cable clamp as it runs vertically up the back of the light support to the top.

I did the work over this weekend and this was for my HF and VHF/UHF ham radio installation. I have a "screw driver" vertical antenna that covers 7MHz to 50MHz (CB is at 27MHz) and one of our ham bands is right above the CB frequency at 28MHz. I was able to get 1:1 SWR on every band. A screwdriver antenna changes the physical and electrical length by operating a small motor in the base of the antenna unit. It rotates a lead screw inside a tube with a an adjustable base coil. This is similar in effect to how you would manually tune your CB antenna by cutting the flexible steel rod a small bit at a time until get the right length and get the best SWR match, I just have a motor do it for me :-).

The point of the above is the ground system and mounting location/process as I have described was sufficient to achieve a near 1:1 SWR match for far greater needs than just one band (CB in this case). That should give us confidence that getting a CB antenna mounted and connected in this way should be capable of a perfect match. If not then the antenna, the grounds are not done right, or the tuning process was done wrong (such as starting with a rod that was too short to begin with or overshooting the match by cutting too much at one time).

Radio mount idea

My particular radio has a detachable control head. I fabricated 2 sheet metal L brackets that bolt to each side of the seat supports. The holes are not the same on each side so some work is needed to drill correctly.

I then used a 6" wide sheet metal plate bolted to each of the L brackets to create a shelf.

I then mounted my radio with its own bracket to the shelf. I remounted the seat connector that used to attach to a factory L bracket under there to the door side L bracket side. Ensure the seat travel does not pull on the cable.

I ran my control head cable under the seat support and under the right side of the center console (the front part snaps in place vertically just pull the side out and up.) Then shoved the wire under the bottom right side of the vertical center console and under the horizontal glove box area cast aluminum frame. Then over and up and around the right side dash heater vent tube and then back toward the center of the jeep and out between the dashboard top and the window. There is a rubber seal flap all along that edge. There is lots of empty space to stuff wires there.

I have a 2013 and so has a deep storage area on top with a removable rubber tray. I pulled the tray and used the single bolt in the center there to hole one side of a RAM diamond shaped base 1" ball mount. I drilled a hole to the right side and slightly forward to screw down the 2nd hole of base. I used a thin rubber washer under the base and had to slightly loosen the center screw to minimize an annoying plastic on plastic squeak that comes from under the tray plastic.

On this ball mount I mount my choice of GoPro camera, Radio control head or GPS. With various RAM accessories I can mount 2 or all three in theory. I will likely mount the mic hanger on a hook on the center footman loop, TBD.

For GPS/Aux power on the dash top: I have my battery-direct power under the passenger seat using a Anderson PowerPole based distribution block (see West Mountain Radio web site), I ran a #20 sheathed pair of power wire up the center console alongside the mentioned control head cable route.
