Topband: Phasing lines (score: 1): Author: <clive@gm3poi.com>; Date: Tue, 03 Mar 2020 10:30:46 -0500; Hi all, I wonder whether anyone has used LDF4-50A for phasing lines and verified the VF as being 88%. If not have you an idea of any spread on the VF. I want to use some where it could make the diffe; /archives//html/Topband/2020-03/msg00035.html (7,008 bytes)

My impression is that they are very consistent; /archives//html/Topband/2020-03/msg00037.html (8,444 bytes)

I am not surprised the VF does not vary that much because of the construction type. 73 Clive GM3POI Hi Clive, i have used chunks; /archives//html/Topband/2020-03/msg00038.html (9,892 bytes)

Its always best to use an antenna analyzer or TDR to cut all of the cables to the same length. Its very, very easy to do. -- Ori; /archives//html/Topband/2020-03/msg00045.html (8,671 bytes)
