Using about 100 feet RG-8
At the mount, I see about 65 to 66 volts. Inside at the load, it's 62.3 to 63 volts.
I seem to be using 3 valuable volts..

So, right now the load is dissipating 63 / 10 = 6.3 Amps. About 397 watts of heat.
The last test, using a cheap 120vac 100' extension cord was 32 watts better..

I'll have to cut the coax shorter and try again..

Edit:
Not much to cut off, just about 16 feet. Saw a peak voltage of 66.6v and the average was about 66v.
Indoors at the load, it was 63.5v, so it's down about 2.5 volts on average.

63.5 / 10 =6.35 Amps, or about 403 watts of heat.
