I helped some guys set up a 2 meter machine, the radio was a old forest service radio with a 100 Watt PA, converting it to 2 meters , you had to swap the TX and RX crystals for the repeater pair, split the TX and the RX with separate 259`s for each. Turned the radio down to 40 watts to allow a higher duty cycle, Disable the tone burst, and heat up the RX and TX at the same time.
Cat 1000 controller took care of all the functions .
Single Hustler antenna, g7 if i remember right
Duplexers, spend a little money and it is worth it.
Coax..Good coax. hard line if you can afford it, but if it is a short run you can do with good low loss coax, being on the very top of a mountain helps keep the coax short if you get that lucky
4 deep cycle battery's
50 Amp power supply
Odds, ends, cables, big diodes, charge controller, some solar panels if you want back up for the back up, beer for the guys putting the tower up.
If you already got the tower you can save money on beer ( maybe)
