The WOAI 120 over 120 was insulated at the base.

There was an adjustable capacitor across the base insulator. This 
capacitor was designated "Base Tuning Capacitor".

The radiator was center fed with the outer conductor of the coax being 
bonded directly to the top of the bottom section, and with the bottom of 
the top section being fed across the sectionalizing insulator from the 
center conductor of that coax through an "L" network. This network was 
designated "Tuning Network".

There was an ammeter in the "Tuning Network", which was normally shorted.

There was an ammeter at ground level, along the path of the coax from the 
Tx to the radiator. On the Tx side of this ammeter was the notation 
"Antenna Resistance Measured Here".

Presumably, a similar system is being used at WHO (180 over 120), KSTP 
(179 over 179) and KFBK (180 over 180).

I suspect a different system is being used at WOC.
