I keep my base radio in the back, it's a realistic Navaho with USB & LSB. Once were parked and hooked up to shore power l take it up front and set it on the dash passengers side. Unhook the coax from mobile radio and hook it to the base. With that power outlet right there on the dash it works out nice. Of course our tow vehicle also has a USB/LSB realistic with a 5' fire stick antenna and a 1.1 SWR flat match..
But yea it's great having a CB in the FR3 30DS.
Here's a shot of my fire stick on the Jeep.
On Jenny, that's our motor homes name, as l said, l just mounted a fire fly on the ladder up high at the top. It's was a lot of coax to run, a 50' long coax. And at 1st my SWR sucked at over 3.1. So l ran a ground down the ladder and found a great grounding spot on the passengers side frame rail. I used a nice piece of fire wire as my ground wire. As soon as l got it grounded my SWR responded as lowered to a 1.7. A few trips up n down the ladder to tune the tip of the fire fly and it settled at 1.3. Not to bad.
this is my radio in the Jeep.
not the best shot but you can see the fire fly on Jenny.
And just for fun here's a pic of some extra radios l have.
this pic shows the spot on Jenny's ladder where l mounted my fir fly.
and this is a pic at the bottom of the ladder where you can see both the coax and grounding wire going under Jenny.
