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 … WebOct 16, 2006 · The best and most complete source of information on shunt feeding a tower is the ON4UN's book, Low Band DXing.

WebFeb 12, 2024 · The tuning procedure for the shunt fed tower is straight-forward. The driven element and the other parasitic element are effectively floated by inserting a 100,000 Ω resistance at their bases. Calculating element currents confirmed they are negligible in the floated elements.

Webinsulated and series-fed; the other is grounded base and shunt fed. We’ll look at both these types in detail later. Ideally, the electrical length of an AM antenna will be 90 electrical degrees (1/4 wavelength) or more. Antennas of this length provide adequate efficiency and bandwidth.
