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.

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
