There is plenty more on the site, so explore!
Bottom line is to use your coax feedline to also send out a DC
control voltage to tune your Vactrol remotely from the radio room.

I just bought a few vactrol's from B G Micro for use in my K9AY antenna in
place of the fixed termination resistors. Looking at some older posts, it
appears that the way to use them is with a 1k pot connected to the 12v
supply. Is this how folks do this? There's really no documentation with the
vactrols, what about controlling current, etc.?
Thanks,
