Coax length

@Mark Doiron So where is the best possible place to mount an antenna? I am getting close to putting in a Cobra 18, spare tire mount definitely seems easiest with Rugged Ridge bracket. I thought about near side view mirror but then, considered that running up against brush or other might be bad for the antenna.

I've used 3 setups. First one was with Arizona Rocky Roads mounts, sticking above the stock tire carrier so the antennas are above the spare tire. Ham on one side, CB on the other, and although they should be separated more both worked at the same time. I currently use a front fender mount bolted to the fender for my ham, could be used for a CB, it works well. I currently use my aftermarket spare tire carrier mount for both a cb and ham, again raising it above the spare, but I only use either the ham or CB at that location. If I use the ham and the CB, the ham uses the front fender and the CB uses the rear tire carrier. Works fine.

By the way, I did run a ground wire from the tire carrier through the tailgate to a stock small screw on the floor next to the rear speaker. The worst SWR is on the aftermarket tire carrier, but it works. The best SWR I've ever had is with a simple mag mount antenna sitting on the hood!

You definitely need sufficient relief for movement. It's worth mentioning, however, that if there is excess cable in the transmission line, don't loop it up and hide it under the carpet. That loop can cause SWR issues. That's one reason I'm not a fan of the pre-cut cable/connector packages. The other reason is that sometimes those packages have very poor grade RF cable--I've seen them with as little as 15-20% shielding coverage. I recommend buy a high grade cable and high grade connectors, include a few extra feet for mistakes and mis-measurement, run it, including strain relief where needed, and then cut off, leaving a couple extra inches at each end for future repairs. Any exterior connections should be sealed up with RTV to prevent water intrusion.

Might be of interest--some heavy brush starting at 8:00 ...

@Mark Doiron Last couple of coax questions. Any ideas where to score a connector like this? I’m in the same thought process as you, I’ll buy coax cut to length and terminate the ends.
20-100-A3-AH - UHF Right Angle Solder / Clamp Plug - COAX Connectors
I’ve checked my usual spots Mouser, Newark, and EDMO to no avail. All the dang Radio Shacks are gone now.
Found plenty of BNC but that won’t work.
Now for your video, holy cow you weren’t kidding about brush! Man that looked like a blast though. Your one buddy was towing a tent trailer was it one of these?

All those dead trees guessing that was beetle kill? Have a ton of beetle kill here in Colorado.

Another option is a fellow who lives on the other side of OKC from me. Ham operator, he carries quite a few types of cable and connector. Super nice fellow. Might give him a call ...

Funny you ask about the trailer. The guy pulling the trailer and the fellow driving the pick-up took the more open road down to the campsite we were headed to. Trailer puller didn't want to scratch up his rig, and truck driver had driven the route we were on only two weeks prior and didn't want to go through "The Jungle" a second time. And, though that wasn't a Conqueror, after this trip that fellow sold that trailer and bought a Conqueror, which is what he has now. His Jeep, BTW, had a Hemi. In fact, at the time he had two Hemi Jeeps, but now he also drives a pickup. I think he has a Colorado.

The fire stick coax I ordered is 18', one end has the "fire ring" the other is just coax with a solder on terminal
Would cutting the coax at what ever length it takes to get from the antenna to the radio cause any swr trouble, or is it better to keep it at the 18'
I know 18 is 1/2 wavelength, the antenna is 5/8, but the coax is "shielded" so isn't it more or less just a way to connect the radio and antenna
