Phred,
you should make a blaw knox copy in 1/7th sale size, or whatever would put you at around 100 ft. Paint it up up red and white.....insulate the base from ground.... b cooler than ice cream....
Theres a Blaw-Knox tower just north of here in Manchester. The transmitter building is a small but classy looking brick structure at the base of the tower. I think it's WGIR 610 AM.
The station lost the original WOODEN tower in the hurricane of '38. The concrete pads of which can be seen still in the big field around the tower.
It's visible right next to the highway as you head north (Rt 3) and is very cool!!!
