[ARC5] arc5 as antenna tuner

I used this arrangement for many years when I was in the service and
traveling alot. I used it to match a Galaxy V MkII with a 50-ohm output t=
o
a 135' Windom made out of WD-1 commo wire, nominally about 600-ohms. Two
cautions: The 'dip' point with this setup is very sharp and will take
awhile for you to find; and you will need a very good ground.

Interesting, because I used an ARC-5 tuner with a 300 watt Galaxy III. I
wired the roller and one variable cap as an L-match to tune random single=

wire antennas. The chassis I used had been stripped clean, so I just put
the roller in its proper place but remounted the cap, without worm gear
drive, below chassis so that a shaft extension came out through the front=
.
They were connected with a ceramic feedthrough bushing that also served a=
s
the ant connection point. =

Never had a good ground, often being in a dorm or apartment building, so =
I
occasionally had RF in the shack for certain antenna lengths. A
counterpoise can help with that though. It was a bit tedious finding the
settings for each new location.
