Dudes. I have a fantastic SWR. I've talked from British Columbia to Guadalajara. This thread was about RF getting into my GPS and subwoofer amp, and how a cheap-ass Pringles can CMC choke that shouldn't be working is actually kind of helping.

Guys! I have to get to bed here, I wake up at midnight to get my truck going down the road, but I am going to do an in-depth video review of the new McKinley's soon. I want to have the time to do a nice detailed review. These just might be the best modern mobile CB radios ever designed. I can't...

It's a mirror mount with a heavier-duty stud. Goes through the roof panel, and support bar. Meter says ground is good. Yes, I have to clean up the hole. Haven't found the right grommet.

From you, w9cll, I knew that was coming. It's alright. It's all part of the game, and I'm always willing to listen.

Yes, sir. Did that.

I spent a long time experimenting with different lengths, shorter and longer, tried 3 different coax types, including LMR240, for both the amp jumper and the antenna feedline, all with varying SWR's, and my 9' whip loves a 9' jumper, and 18' run to the antenna of the cheap clear-jacketed RGX...

Running a President McKinney mobile, Midland HF747 amp, which is putting out between 90 and 110 Watts, 9' whip dead center the roof, 9' RG8X coax radio- to-amp, and 18' RG8X amp-to-antenna. Cheers!

Great information, friend! A couple other chaps on here also recommend beads, so I shall take y'all's advice. I have been looking online, and will make a purchase soon. Cheers! Dean from Denver, Colorado. (I'm born and raised in Chicago, hence the handle.)

It takes a while to get to know me I guess. I like to get out there and have fun and joke around and act stupid. Usually at my own expense. In all seriousness, RF was throwing my Garmin GPS off, and making my subwoofer amp hum. First I threw together one using PVC pipe, but I felt it was too...

You know I was actually thinking about leaving the chips inside. They may have provided a crisper audio response.

Okay, I'll pick some up. Gracias.

Yeah, maybe I'll keep this design the way it is. It might keep my wife out of my car for good.

It is quite ghetto fabulous, and it works. My wife is convinced that I need help, but it's alright. I'm going to make another one with a plastic form, and use the formula that was given above. In the meantime, I hope no one thinks my car is rigged with a bomb.

Yeah, it's cardboard with an aluminum film on the inside. I was wondering if that would have an effect. My first one was made with PVC but I felt like it was too heavy. It has to be lightweight. I'll try again. This one's working, though. 1.1 SWR with my 9' whip, reduced noise, no more RF...

Actually it's about a half a Pringles can. 8 turns of coax with fish tank hose for spacing. Clear Gorilla tape, with the sticky side out around the can to hold the coax and tubing onto the can, then another layer over the outside to seal the deal. I sell them for $99.99. Free shipping. Just...

I don't have anything against that setup. It was exactly what I did on my first YJ, except I did it on the passenger side. 4 foot Firestick. I could never get the SWR below 2.5, and my range was 1 or 2 miles- if that. For communicating with fellow Jeepers on a Jeep trail, it will work, but in...

I owe God a favor. When I drilled the hole for the antenna mount, I thought I would be drilling through the roof, and nothing else. I had a circular saw blade ready for the underneath support. Turned out that the roof panel has these U shaped support bars underneath. God was looking out for me...

Yeah, on the ghetto scale, it runs about a 6 out of 10, but it holds the mic perfectly.

Yeah, I'm in the process of ditching the beehive mount, and replacing it with just a heavy duty stud. I'll post a pic later.
