Shunt feed tower 160 meters
WebThat's the result of modeling with EZ-NEC, initially undertaken because I got looking at the gamma match dimensions on my old Cushcraft 4-element 20-meter beam, and wondered if it might not be appropriate to scale the spacing of the gamma rod from the driven element by a factor of eight (the ratio of 20 meters to 160 meters).
