Bogner used to manufacture a null fill UHF base station antenna; I think it was called the "Penetrator." If I remember correctly, Celwave manufactured a similar product. Anyone out there ever use one of these? If so, were they worth the money?
I recall they were very heavy and very expensive; I always wondered if they really did improve repeater coverage. I see a few 800 & 900 MHz models in service; most likely being used by paging companies. But I don't think that I've seen a UHF one in service lately. In fact, the only ones I ever saw were in service at sites using transmitter & receiver combiners. I think that they were very broadbanded. I'd be interested in hearing from anyone who ever used one for a ham or GMRS repeater. Are they still manufactured? Thanks. Tony
