Cb radio install

[Farma Parma]

Earthing the Antenna Base or Making sure there is plenty spread of the Ground Plane side of things is as crucial as the length of the antenna.
Ive tinkered with CB Radios for the best part of 30years now.
Used Wires from the underside of the Antenna Base to various corners of cab posts etc etc & mind that can make all the diff

Is this no good like this then? Don't want it on cab cos need to be able to go in buildings

It'll work best on the top of the roof on a bracket between the cab lift bolts or get a bit of plate either between or on 1 of them and put a mag mount on then if you're going into a shed low enough to catch the actual spring part of it chuck it onto the back mudwing.

If you really don't want to do that at least put it up onto the mirror if you can get in with your beacons on it'll not bother an ariel.

As said above,that seems to be the best way on our Deere's for mounting a aerial

Never used CB's and have been using 2-way radio's between our tractors. Does the job but keeping them charged is a nightmare.

Looking to stick some CB radios into the tractors so can you guys recommend a kit?

There isn't a CB style 2-way radio kit that fits into the tractor so if you are out in the field, you can still communicate with the man in the tractor via his unit?

Cheers

Checkout Motorola gm350 on eBay, they are getting on abit now but are what I use in all my kit !.

Having the same trouble as the OP so im resurrecting this thread. Got a few cb and aerials off a chap who was swapping them out for 2 ways. Have the cb radio wired from the radio power source, the antenna is mounted on the wing mirror bracket, all paint cleaned off. SWR is showing 3 and over for all channels. I've ran a wire from the chassis up to the antenna and its no different, so I think it's not the earthing causing the interference. I'll maybe get a new coax cable to rule out a short in it. Anything else I should try?

I'd try a bit of flat metal a good foot square. Bolt the aerial through this, put it onto the roof with a good earth to the chassis (not the wing mirror, they're never a good earth). This will give the aerial a good ground plane and stop so much transmission signal getting reflected causing a high swr. If it's still high, then change the coax. If it's still high, check swr on cannel 1 and 40 are similar. If there a big difference, the aerial length is wrong.
