Cobra 75 and Ultramount installed

Just finished installing my new Cobra 75 WX ST, Cool Tech Versamount2 dash mount, and 4' Firestik Firefly on the Cool Tech Ultramount license plate mount. Oh dear gawd, my back is killing me!

The radio was pretty easy, the Versamount was even easier. The antenna mount was much tougher, especially grinding and reassembling the license plate holder. Kind of an over-engineered PITA.

Anyway, SWR after tuning:
1 - 1.7
19 - 1 (needle doesn't move)
40 - 1.8

The Firefly tip is screwed in as far as it'll go, so I think that's as good as it's gonna get.

Parked down by the freeway and listened to 17 and 19 for about a half hour. Didn't hear a peep from all the semis going by, but three WX broadcasts came in loud and clear. I'll have to meet up with someone with a radio (or pop by the truck stop) to see if the CB actually works.

Things I learned:
  • The Cobra is much larger and heavier than I expected.
  • Drilling a 3/4" hole in one's dash for a handset jack is emotionally challenging (I skipped it for now).
  • Do look at pics of other Ultramount installs, the instructions aren't very clear about where to place the drill template.
  • 18' of coax is not as long as you think.
  • I'm old.

Got my Cobra kit from CoolTech on Monday and will get the new 2012 Jeep next week Saturday. Then I will have to do the same installation you just did. Can't wait.

The Versamount doesn't require holes (nor the Versamount2 in my case). I meant the hole that some folks drill under the glove box to mount the 4-pin handset jack.

Just
Can't
Do it ...

Update: After removing the little rubber washer on the Firefly's adjustable tip, I got it to:

1 - 1.5
19/20 - 1 (needle doesn't move)
40 - 1.5

I removed the washer to allow me to screw the tip in further (shorten the antenna) and bring 40 down. Strangely, with the washer removed I had to make the tip even longer than before. SWR is a fickle bitch.

Use some zip ties and mount it to the brace behind the glove box. That's what I did.

I did that as well. I'm talking about mounting the handset jack as shown in this pic (lifted from another forum):



All the hardware comes with the Cobra 75, but I just can't bring myself to pop the hole. On the 2011+, that little plastic area is all one piece with damn near the entire dash. Screw it up and things get spendy.

I didn't mount mine. I just shove it back up under the dash when not in use and pull it down when needed.

I actually drilled the hole in my dash and it looks very clean when your not using the CB. I may not have choosen the best place to moung the clip to hang the CB from but I like it.

Guys, just take out your glove compartment box, it is REALLY easy to do. Then just look in there and see what is behind the dash. It is really easy to find a good place to drill. ONE NOTE though, before drilling the hole in the dash, get your fingers inside the dash to see how hard it is going to be to hold onto those very small washers and nuts and then mount them on the screws. I didn't consider that and discovered had I drilled a little lower it would have been easier to get the screws tightened down.

Good luck,

Not a big deal, buddy did his in 10 minutes. Just be sure to measure twice and drill once. On thing I don't like about his install on his 2011 is that Chrysler felt the need to round off that area so he ended up mounting his on the very bottom of that panel. I'd be concerned about the passenger kicking it.

For you 75 owners, I'd HIGHLY suggest you remove that little screw holding the plug together (on the end for the CB itself), and put a drop of loctite on it. I removed my CB from my Jeep when not using it, and over time, that screw worked itself out and I didn't notice it. After a while, the wires all frayed and broke. You loctite that screw in and you can avoid that problem.

how is the cooltech license plate mount holding up? I had their tailgate mount but sold the jeep. I just purchased a jk w/ a hardtop and I would like to keep the rear window open when doing trails, but the antenna will most likely get in the way.

I'm leaning towards the license plate mount this time around. I just need to know if they can handle the stress of a dual purpose rig. I also had a problem with grounding with my first setup (non cooltech/ license plate mount). I'm just hoping I don't have to waste my money in purchasing something that will break in the long run.

if not, the cooltech tailgate mount will be in order.

I had the Ultramount on my last JK for over a year- no issues. Moved it over to my JKU this week. The license plate mount is a pain indeed. Of course, I ended up pinching and ruining the coax so my SWR was way high. I bought a multimeter and verified that. In went the new coax and all seems good though I need to SWR it again to make sure I did not pinch it when putting the trim back.

As far as the CB, I chose the Uniden 520XL since it is the smallest. I have not tried a Cobra but none of the Cobras would fit properly above my rearview mirror. I use the Zebramount for that.

I have noticed that the Firering type of coax that Cooltech includes has a very soft cable covering. It pinches really easily, unlike cable TV coax. Just have to be really careful. I really like the Ultramount because it looks clean and almost looks stock. The coax is also not moving back and forth each time you open the tailgate. I ground directly to the battery and have no RF grounding straps. I may add one later.

dawhitesJKU- it holds up well for me and has held up well on the last JK but if you whack your license plate bracket hard enough to break it, it will not hold up. I have never actually hit my license plate bracket on the trail.

Thanks HK_Runner for the response even though it was a little late since I saw a pic of someone bending the antenna and it didn't break. I purchased the license plate mount, and went with uniden 520. Compared to my previous cobra though, i felt like I downgraded and should've stayed with cobra. The trigger is too sensitive when I use the PA system. I never had a problem with the cobra. I just ordered a swr so I'm not gonna transmit/receive till I receive it.

Yeah, the antenna will bend just fine. It is the license plate bracket itself that is a problem- IF you hit it on a boulder or tree. I have seen a couple of guys knock them off but they wheel in some pretty crazy spots. I don't wheel that hard though stuff can happen on a tight trail. I'd like to try a Cobra but I don't have the room above my mirror. I wish they would make one as small as the 520 XL. It is the height mainly though depth cannot be much more- I have space for added width. My 520 XL sends/receives very clearly. The Cobras do seem fancier. Like I said, I'd like to try one.

update... someone took my usual parking space this am at work because I was late and I had to go to the 6'3" parking garage. everything cleared except the antenna barely hitting the signs (about 3 times) and caused it to whip back and forth. I checked everything afterwards and the antenna was still secured. the mount is pretty sturdy enough for my preference.

Can someone post some pics of their hole locations and how they mounted their mic's when using the cobra 75.
I once saw a pic somewhere on the forum and it looked really clean and factory looking.

I really dont want to put screws into the upper dash area to hang a mic.

If you go with the ultramount, you don't need to drill holes.

Im interested in the hole in the lower dash for the coax connection.
I thought the mic holder ( clip ) screwed into the dash also, how does that attach also.

How do you run the coax back to the antenna with the cobra 75 and what to do tie into for power, fuse box ?

The mic holder is called the Versamount or the Versamount 2, depending on the year of your jeep. You can find both of them here, CoolTechLLC. The Versamount mounts in the seam between the factory radio and the dash, with no drilling. The Versamount 2 mounts between the grab handle, above the glovebox, and the dash, with no drilling.

I mounted my 75 behind the glove box, on the metal brace. Ran the coax from the tailgate, under the carpet and plastic floorboard trim, and then up behind the glovebox. For power, I wired directly into the battery and grounded with one of the several spots on the tub. If you check You Tube, you can find the video. Also, look at rightchannelradios.com, they have installation instructions and trouble shooting tips.

bbtj or anyone, did you drill the hole in the lower dash area under the glove box for the connection or just zip tie that under and connect the mic cord under there ?

How is everyones cobra 75's holding up, my local cb shop says they dont last but maybe a couple years because of everything being in the hand held portion it over heats .

I didn't do any drilling, I just left it hanging down. I've had my radio for about 4 years now and no problems.

A SWR meter is connected between the antenna itself and coax antenna cable. The mic stays plugged in to where it normally connects.

The SWR meter would not be connected between the mic and the box. It would be connected between the box and the antenna.

Edit: beaten to the punch.
