Topband: Detuning Tower

2012-11-18 Thread Clive GM3POI
Hi All, I am thinking of a new Beverage that passes fairly near (50ft) of A tower that is not used on transmit as a vertical but is probably resonant in the 1.5-2.5mhz region. I would like it not add any noise to the beverage, a big ask I think. Is it just best

Hi Jorge, Beverages don't have to be either straight or level. It would be better if it was straighter, but if that's all you can do at your QTH then by all means put it up that way. My Europe/Australia Beverage has a 15 degree bend in it and hears great. I didn't model your description, but I

2012-11-18 Thread Michael G. Carper
Hey guys. I saw a few items in a Google search where guys had converted their full-size G5RV into a T antenna on 160m. It had something to do with adding the obligatory counterpoise and shorting the feedline. This would turn the antenna from a horizontal radiator to a vertical radiator.
