So Brock is the UHF to be tucked away out of the weather or out in it but where you can access its features ??
Can recommend the TX4600 if you have room......have seen them take a flogging on cow cockies quad bikes in all weather, used one in my 4x4....big buttons, knobs , numbers, clarity, etc.
Used a TX3220 (because I had one spare) on the 1100 mounted in the Topbox, only used Ch 40 so was not a big pain.
Now use a Uniden UH078sx 5w/1w with a 6.5 dbi and 2dbi gain antenna.
Cheers
