On 2 of them, I used 1 FT-240 mix 43 core (will be running these as portable antennas on LP) and one one of them I used 2 of the same cor; /archives//html/Towertalk/2017-07/msg00159.html (7,317 bytes)

Re: [TowerTalk] EFHW (score: 1): Author: <john@kk9a.com>; Date: Sat, 15 Jul 2017 13:19:26 -0400; I have no experience with end fed wires but I imagine that the counterpoise has an effect on the resonant frequency.

If I increase the length of the wire to bring the frequency up on 40, it will resonate around 3700, on 80 which is not what I want.

Half wave or full wave end fed wires are not influenced much by the counterpoise. Quarter wave and 3/4 wave wires are influenced considerable by; /archives//html/Towertalk/2017-07/msg00165.html (7,394 bytes)

HF, which is why it's also lousy for chokes. #31 and #43 ARE just fine for RX antenna transformers below 20M. 73, Jim K9YC _____; /archives//html/Towertalk/2017-07/msg00167.html (8,091 bytes)

[TowerTalk] EFHW (score: 1): Author: "Wilson Lamb" <infomet@embarqmail.com>; Date: Sat, 15 Jul 2017 17:06:21 -0400 (EDT); It's interesting that hams have been using end fed wires since the beginning, without fanfare, often after being told they were hard to use and a poor choice. Now someone has christened them EFHW and; /archives//html/Towertalk/2017-07/msg00168.html (8,694 bytes)
