I finally made time to install the above subject radio in my 21 Chevrolet Silverado 3500HD Dually Diesel Pickup. I've been wanting to do that since I bought the Truck almost 4 years ago. I did make time for the Motorola XTL5000 UHF High Powered Remotd Mount sometime ago. The installation was a piece-of-cake and I had no problems with the install.
The subject radio is the 840 channel version and I only have a few VHF channel programmed in the radio. I am not a licensed Amateur Radio Operator, thus I do not have any HAM channels programmed. The VHF radio will mostly be used for my car racing activities, in addition to the UHF radio. The UHF radio is CPS tuned for max 50 RF watts for GMRS.
I'm using a Laird/ T E Connectivity B1443S Antenna with Spring 2-3 dB Omnidirectional mounted on the cab roof along with my CB K40 and B4502 UHF antennae. The VHF antenna was tuned with the VSWRs for 154 Megs at 1.05:1 which resulted in .5 reflected at 55 watts measured with my Bird 43. The radio draws about .5 DC amps on standby and about .6 amps receiving. The radio draws about 7 amps transmitting. Both radios draws approx. 14 amps when both radios are keyed simultaneously.
The radios draw their power directly from my auxiliary battery which is charged by an auxiliary alternator, and are connected to a chassis grounding point.
