I always wondered about that. That was way before computer modeling, of
course. Even today, modeling traps is very difficult, hence all the

When I was the Natl Sales Manager for Hy-Gain/Telex in the 90's, I met the
guy that designed the TH-6. Hy-Gain had a nice antenna range and he said it took them 4
