Hi Charlie,
the mast for his inv-V snapped during Hurricane Sandy and I attached
the apex to the highest remaining part of the PVC mast that snapped,
that I can reach up to. So for this moment, his Inv-V is more of a
dipole

Fellows,
Thanks for the on & off list replies, I just got back from a weekend
away & read through them all. Part of me wants to just leave it as is

will fail. Since I need something to relieve stress from the

Unfortunately, optimum balun impedance and design really depends heavily on
the application,. There is no magic design that works best for all
applications, and the issue is so complex that almost any article falls
short.
For example, the 5000 ohms pure R will not work at 1500 watts with all

His antenna in an inv-V with 40 & 80 elements though he never uses 40
any more. I needed to fell a couple of trees to remove branches that
were touching his copper

I am sorry! That was not very clear.
The info on chokes worked wonderfully for me on 80m and 160m using the Big
