Topband: Phasing lines

[dj7ww at t-online.de]

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.

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 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
