I'm cutting a 40 degree and a 20 Degree Delay line using RG6 at 1.83MHz
for a receive 8 circle array ! I know the velocity factor of the RG6
and have all the math worked out .
After doing the calculations and trimming the RG6 back , I'm looking
for X=0 at 4.118 MHZ ( or as close to X=0 as possible )
Now to my question: I'm finding the X=0 to be a broad range , looks to
be + - 50 KHz on my MFJ 259b .. I know , I need a better analyzer ...
Can I double of quadruple the frequency to narrow the span where X=0?
Thanks Ed N5DG
