[IRCA] Fwd: Re: Topband: Vertical Antenna on a cliff above the Sea



from the Topband Reflector:


N6BT, the excellent designer behind the original Force 12 antennas, has studied this extensively and gave a great presentation on the topic at Pacificon this fall. He showed that a vertical antenna at the edge of a bluff has a strong propagation advantage in the direction of the dropoff. The antenna still needs radials, just like any other vertical (other than a half wave).

Pacificon is a radio amateur convention; this last one in San Ramon, CA. At first glance, I cannot actually find anything specific about this topic on their website, though N6BT did give a presentation on antennas. Anyone know anything further?

best wishes,

Nick
