I have a 4x4 off road SUV and overland with various groups in areas where cell phones are of little to no value. Thus the need for radio communication such as HAM and GMRS & CB. Why GMRS & CB, because there are many in several groups who don’t wish to take the time to take a test for ham, or pay the license fee for GMRS. I do have a HaM, and GMRS license Sometimes our outings involve aircraft. This the need for aviation radios as well. Aviation is VHF. And of course we know GMRS is UHF. I also wish to have two Kenwood dual banded vhf/uhf ham mobile radios. (710ga, 71) While I have made use of the mod capability to use GMRS Channels 15-22 462mhz on the Kenwood 71 and 710 radios. All these radios create the need for 4 antenna. 1 CB antenna, 1 VHF Antenna for aviation radio 2 vhf/uhf antennas for the Kenwood 710 and 71 radios So my mounting options are front steel bumper, or engine hood, somewhere on my 4’x7’ metal roof, or my back bumper/tire carrier. One other note, is that my vehicle is Kevlar coated. So hood mounts and roof mount magnetic mount antennas don’t provide an adequate ground plane. I do have a steel roof rack which is NOT coated and has provided a decent ground plane for my CB antenna. Roof rack is 3’x5’ Recommendations on where to mount each of the antennas? As well which antennas you would consider for the uhf aviation, and the 2 for Kenwood radios? CB using a single timetable fiberglass “fire stick” Your advice is greatly appreciated.
