Dear "me" Not big at all. It is intended for high VHF and UHF. I have
it mounted on a tube that is supported in turn by the top section of a tower, which became surplus after a rotator change. The whole assembly is in a second story room with the main computer and can be rotated by hand. It is deceptive to put numbers on the size. The reflector consists of five doublets each with a tip-to-top length of 26.5 inches and a total height of a little over 16 inches. The twin "driven" elements are spaced about 6.6 inches in front of the reflectors (obviously the reflectors are only effective for UHF). The tip-to-tip length of the driven elements is about 34.5 inches (giving a predicted 0.5 WL resonance towards the bottom of the higher VHF TV band). Each driven element is coaxial with a fan dipole that should have a resonance somewhere in the UHF band. Thus one expects a small gain with a small F/B in the higher VHF band and fair gain with good F/B in the UHF band. I hope that this is of some assistance. I regret that you believe you must be anonymous. Regards, Mac N8TT -- J. McLaughlin; Michigan, USA Home: wrote in message ... "J.
