How to shunt feed your tower - Simple Ham Radio Antennas

WebIt's very broad-banded, with the 2:1 SWR points below 3.5 and at about 3.9 MHz. This sloper works better (higher sigs on TX and RX) than the shunt feed on 80 did. I have seven #18 radials around the tower. Five are about 100 feet long and two are about 35 feet or so. BUt my lightning ground is 135 feet of #2 solid tinned copper on twleve ground ... WebTo shunt feed a tower so as to use the same as a radiator in the 40, 80 or 160 meter wave length bands, a gamma rod or gamma matching section, which may be simply an electrically conductive rod or wire, is mounted in substantially parallel relation to the tower spaced apart a relatively small distance therefrom. WebThis should be done by adjusting the antenna’s resonant point. If it is under 1.5:1, move to 40 meters (the actual frequency isn’t important). If the lowest SWR is higher than the 80 meter point, squeeze or elongate the coil, and readjust the antenna to the lowest SWR. The lowest SWR point should be set half way between the 80 meter point ... photo fingernails

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.

WebFeb 21, 2024 · Very nice. I just use the MFJ anylazer and tune for 50 ohm J+0 reactance ,or close as I can get. I like to keep the VSWR under 1.7:1 at the dip. Or return loss under 18. You will need a shunt coil at the feed for the lower frequencies. That antenna will be 12 ohms on 75 meters or something very low. Here is my experimental 160 meter loading coil. WebThe coil is 20 turns, #12 solid, 1 & 1/4 inch I.D. ( closet hanger dowel works great ) spread to 5" long, ( thats 4 turns per inch ). One end to feed point, other to ground. Clip lead from ground taps up the coil to adjust the inductance used. Eight turns works perfect for 40m, and 4 turns for 20m. Mind you, this is on a wagon - results will ...

WebJan 14, 2012 · Shunt feeding a tower is not an easy thing to do. You really need consider every part of the existing antenna system, including the tower/ mast. A good design for a shunt feed tower needs at least 120 radials laid out, each 250 foot long, and this would work on 1.8 and 3.5MHz. WebThe Folded Unipole. Author: Edmund A. Laport. An alternative method of shunt feeding a vertical radiator one-quarter wavelength tall is that shown in Fig. 2.13, which may be called a folded unipole, from very-high-frequency terminology. By this method, which is one-half of a folded dipole, the total antenna current is divided between two ...
