1. [TowerTalk] Placement of coaxial matching stub at yagi feedpoint (score: 1): Author: "Bill Conwell" <bill@conwellpdx.com>; Date: Tue, 13 Oct 2015 07:22:47 -0700; I'm doing some EZNEC modeling - looking at converting a KLM 40m 2 element yagi to 30m. The feedpoint impedance is about 35 + j25 ohms. By shunting it with an open stub of about 100 inches of 75 ohm c; /archives//html/Towertalk/2015-10/msg00090.html (7,704 bytes)

If so, you can easily adjust the element spacing and lengths so the impedance is 50 ohms. John KK9A I'm doing some EZNEC modeli; /archives//html/Towertalk/2015-10/msg00092.html (7,902 bytes)
