My experience with LDF4-50 and LDF4-75 is exact;y the same as Peter's.
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. ----- Original Message ----- From: [email protected] To: [email protected], [email protected] Sent: Tuesday, March 3, 2020 3:39:21 PM Subject: Re: Topband: Phasing lines I have used LDF4-50 and LDF 4-75 by RFS for phasing lines on HF bands. They did as expected with 88%, however on VHF/UHF I would measure how they behave. 73 Peter -----Original Message----- From: Topband [mailto:[email protected]] On Behalf Of [email protected] Sent: Dienstag, 3.

If not have you an idea of any spread on the VF. I want to use some where it could make the difference to cable length. However nothing will be assumed it will be measured. I note from the spec that they give a tolerance of 5% but I doubt some how that the VF varies that much. 73 Clive GM3POI _________________ Searchable Archives: http://www.contesting.com/_topband - Topband Reflector _________________ Searchable Archives: http://www.contesting.com/_topband - Topband Reflector _________________ Searchable Archives: http://www.contesting.com/_topband - Topband Reflector
