For that amount of cable, at 50 cents a foot, I would probably do a
small solar setup. What is the latitude?

We're looking at 600 to 700 meters of singlemode fiber and a small
NEMA4X junction box with the radio on the far side of the hill,
containing a SC-SC patch cable bulkhead and a meanwell DC-DC converter.
It looks like based on the wattage of the radio and voltage drop
calculations for 18-2 cable that we can get away with a 56VDC power
supply at the power source, dropping to not lower than 35VDC at the
receiving end, which will be fed into a DC-DC converter to bring the
output back up to 52.5VDC for the radio.
If you had to run 600-700m of 18AWG cable outdoors through a forest,
how would you do it? SJOOW type cable may not hold up over a long
enough time. Ideally something that is more armored than SJOOW (it can
be much less flexible if needed). Cost is somewhat of a factor.
