Topband: 4-square phasing (score: 1): Author: "DAVID CUTHBERT" <DAVIDNNAN@MSN.COM>; Date: Mon, 13 Dec 2004 21:28:28 -0700; Ron, if I have it figured correctly the 3/4 wavelength lines will cause the two extra elements to lag by 180 degrees. You can fix this by doing one of these: 1) adding 180 degrees of line to the two; /archives//html/Topband/2004-12/msg00175.html (6,950 bytes)
2. Re: Topband: 4-square phasing (score: 1): Author: "DAVID CUTHBERT" <DAVIDNNAN@MSN.COM>; Date: Tue, 14 Dec 2004 07:05:02 -0700; Ron, that's right. It would be best to limit the phasing line lengths to 270 rather than 450 degrees. With changes in frequency the phase error will change faster with a longer line.

I'm a little busy with work right now. Be very careful what balun you use if you decide to invert phase on the short legs. Many b; /archives//html/Topband/2004-12/msg00203.html (8,573 bytes)
