Solar Powered GMRS Repeater
I have installed several repeaters that run totally on Solar Power. They have been working now for 3 straight years without failure: I have installed Kenwoods 25 watt, BridgeComm 25 watt, and one repeater is a two ht with duplex and controller. They have all worked without losing power. Main power source is 140 watt solar panel, 30 amp control, and 100 AH battery. Talk time is calculated on 2 hours of continuous talk per day.- Album created by div3405

Misc. Radio Gear
I have a few Motorola radios. The XPR6550 is a good choice. You can buy them for reasonable prices. They also use a standard SMA type antenna connector. The XPR7550 is a better radio, but they are expensive used and have a funky stud type antenna port. So, if you need to use an external antenna you want the XPR6550.

Under-canopy Headache Rack Ground Plane
When outfitting my 2015 Nissan Frontier I wasn't interested in putting visible antennas and drilling holes in the factory sheet metal. Since the truck is equipped with a tall fiberglass canopy ("camper shell") I decided to basically use the canopy a a poor man's radome. Took an old headache rack from a smaller truck, modified it to fit within the shell and to accommodate a pair of modded telco rack shelves to serve as ground planes.
I went with a sheet metal mount, drilled a 3/4" hole in the rack shelf as far forward as I could with the angle of the fiberglass canopy. It's a bit more aft than I would like but I can always fabricate an extension for the shelf by cutting up a second shelf, or possibly make something to go between the two separate shelves to extend the ground plane.
To get the cable to the radio I used a factory plugged hole in the forward wall of the bed, through a hole drilled in the plastic cabin pressure vent (so the vent remains functional, didn't just push through the vent) and I pulled the unterminated cable through, and soldered on a PL-259 connector.

A few personal photos from when I was an Electromagnetic Spectrum Authority and lived in NYC. I was one of the few people that had carte blanche access to almost any rooftop or tower in the country.

Citicorp Center WHQ - 153 E 53rd St. - 915' AGL
Chase Manhattan Bank WHQ - 1 Pine St. - 853' AGL
Chemical Bank WHQ - 270 Park Ave. - 747' AGL
The GM Building - 767 Fifth Ave. - 705' AGL
Citicorp Court Square - 2501 Jackson Ave - 685' AGL
One New York Plaza - 1 South St. - 630' AGL
The New York Palace - 455 Madison Ave. - 593' AGL
