Planning on putting up a 160 vertical, but of course a 1/4 wave vertical is out
of the question here in HI since we have a height limitation.
Here's the question: I'm putting up around 50 feet of 3 inch aluminum tubing
(left over from various antenna takedowns). I plan on putting up on top of
that around another 10 or 15 feet of smaller diameter stinger for a total
height of around 60-65 feet. I obviously need to make up for the lack of
height and I was planning on making a top hat of four wires coming down from
the top of the antenna at around a 45 degree angle. The problem is how long to
make each of those wires. My guess is around 25 feet based on my past
experience in making Tee-topped 80 meter verticals. However, it is only a
guess and I don't feel like yanking the 3 inch pipe up and down a bunch of
times to get it just right.
I know some trimming will be necessary since this is not an exact science. I
just need an educated guess for where to start with the length. Any ideas?
