Shunt fed tower
WebShunt Feeding a Tower The best and most complete source of information on shunt feeding a tower is the ON4UN's book, Low Band DXing. It contains a wealth of information, several shunt feed matching methods, and verifies that a vertical needs to be at least an electrical quarter wave in length at the lowest frequency being used.

A slant-wire was used to shunt feed the cell tower with KARR’s 740-watt signal. Tom Vernon. Tom Vernon has been a Radio World contributor since 1983. WebApr 3, 2000 · If the answer is yes, the tower can serve as a vertical on the low bands (80M and 160M). I put up a 50 foot Glen Martin tower last year with a Mosley Pro 67-C beam (44 foot elements on a 24 foot boom) at 55 …
WebI attached the shunt wire for 160m at the top of the tower and the shunt wire for 80m at the top of the center section at about 45 feet. Fortunately, by adjusting the shunt wire spacing, these points were close to 50 ohms for the real part of the impedance on the two bands, so only a single "gamma" capacitor was needed on each shunt feed to tune out the inductive …
WebNot all towers have base insulators. FM and shunt fed AM towers do not need them; the bottom of such towers is at ground potential. Most series fed AM towers though do sit upon ceramic insulators to keep the tower from contacting ground potential. WebFigure 9; 90 Degree Tower Slant Wire Fed Example Like the 60 degree example, this antenna has a quite acceptable circularity, + 0.6 dB, and a vertical pattern which is virtually …
