[Milsurplus] Suggested tuning for ART-13 into a 50 ohm antenna on 75M?

[Mack McCormick]

Friends,

How do you have your Antenna Loading controls setup for max forward power
and minimum reflected power? I can’t seem to find a combination that yields
high forward power with minimum reflected power. Your suggestions are most
welcome!

I’ve owned ART-13’s for a long time and repaired many. I find the best
tuning solution to be COARSE ANT LOADING at 6 (L Network) and a 4000pf cap
from the bottom antenna terminal (RF side of the blocking cap). However
this only gives about 60W forward power but almost zero reflected power.
I’ve tried other combinations that provide more forward power but they
always yield a lot of reflected power.

I understand the ART-13 was designed to work on an aircraft antenna of much
lower impedance (around 10 ohms).

Thanks in advance,

Mack
