Background
In order to operate military radios
that were designed for use in a military vehice in a fixed
installation one of the things you need is a source of "24 Volt"
DC power. I put quotes around it because in reallity a
military vehicle will have anywhere from 20 volts (battery dead)
to 30 Volts (full charge).
eBay magic search words: 1000W 24V
Power Supply
about $200 including shipping
(arrived well packed via Fedex in 7 days)
Concerns
This is a switching power supply so
there's a potential problem with noise getting into
receivers. Another potential problem is when transmitting
the RF may get into the power supply and cause it to do something
that's not normal operation.
Description
The panel contains left to right:
Output binding post terminals with ring terminal lugs that can
accept a wire conductor up to 0.190" diameter. 6 AWG rated for 60
to 100 Amps.

16 AWG wires (each wire is rated 13 Amps).
