It was a 4 bay dipole antenna for 146 mhz. It was on top of a 100 foot tower and a hill about 400 feet haat. Replaced it with a station master. Getting ready to replace the SM with another dipole aray. Thinking of mounting it where the bottom of the antenna is about 10 feet below the top of the tower and putting a bracket at the top. This will leave about 10 feet sticking out of the top of the tower.
Probably will set the lower dipole and the next one up at tight angles to the tower, one in each direction and the two at the top at right angles to thoes. Hopefully this will give up an omni directional patern. __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo!
