You can solve that yourself.

Get out your amateur radio handbook and check the resistance of #16 AWG per 1000
feet. Multiply that by 0.3.

Get out your SGC specification and find out the current being drawn while it is
tuning.

Use Ohm's law to calculate the voltage drop. Subtract that from 13.8. The answer
is the voltage at the SGC.

I'm not being facetious. I'm teaching.

hi

i have 150ft of 16ga cable going to my roof sgc tuner

my astron is putting out 13.8v in my shack

given the gauge of the wire and distance etc

what would i expect the voltage to be up at the roof?


tnx
