Also, in the same ad, the one-way valve to stop those pesky waves from
traveling back! :)
Tom, you made my day!

Tom, I'm surprised at you. After all, the author says "...With over 40
years as an amateur and over 30 years as director of engineering for a group
of television and radio stations, and with my experience as a communications
engineering consultant, I've learned some very valuable lessons with regard
to the radiating element of the station." How could you doubt someone with
credentials like that?
