(score: 1): Author: "Richard (Rick) Karlquist" <richard@karlquist.com>; Date: Tue, 19 Dec 2023 06:24:27 -0800; I did exactly the same thing as what Tree describes. It worked pretty well using just a Kenwood TS-570 as the 2nd receiver. Getting a really deep null on the loop requires attention to various detail; /archives//html/Topband/2023-12/msg00061.html (10,120 bytes)

My property is heavily wooded, with antennas among loblolly pines, oak, maple, gum, etc. For in-band listening while; /archives//html/Topband/2023-12/msg00082.html (12,811 bytes)

However, I think it is unfair that your RX antennas are 1000 feet closer to Europe. Given the fact that you are so close to Europe (compared to us on; /archives//html/Topband/2023-12/msg00083.html (14,391 bytes)

So I guess the antenna pattern is simply the spacing of the antennas and the phase you dial in, but you would need the antennas aligned so the null was in the correct d; /archives//html/Topband/2023-12/msg00084.html (13,936 bytes)

(score: 1): Author: Jim Brown <jim@audiosystemsgroup.com>; Date: Wed, 27 Dec 2023 12:10:57 -0800; I haven't looked at spacing for verticals, but optimum spacing for VE3DO loops worked out to be 5/8 wavelengths, which I am lucky to have. 73, Jim K9YC _________________ Searchable Archives: http://w; /archives//html/Topband/2023-12/msg00085.html (9,412 bytes)
