Hi Clive,
i have used chunks of LDF cable for phasing lines and my impression is
that on VHF, you could trim them by the book and be well close enough.
My impression is that they are very consistent from piece to piece.
That being said, I always tested my lengths after cutting a bit long and
then trimmed them to the actual phase length. (It is more fun to play
with the test equipment!)

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
