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.
