75 ohms resistive at the freqs I want to use and I'm going to feed it
with RG-6, 0.7 dB/100 feet. My radio has an internal tuner to match
the 75-ohm cable, if I need it.


I'll report the results.

wow, it takes eznec to model a dipole for field day now? *not that
many years ago i ran a competition at field day... given a hunk of
coax(with one connector installed), a roll of wire, and some random

contact. *no eznec, a tape measure if you really wanted it, and who

You take all the fun out of a guy's efforts.


too many people spend all their time analyzing antennas and no time
using them.

And some people spend all their time complaining about other people
analyzing antennas. Take your own advice.

That is a disease that affects, as a SWAG, about 80% of the core
population here.

Then there are the people that ask questions because they are trying to
actually build something. Who almost always get what is effectively
GobbldeeGook in response.

All they just want to know how to make something that is "OK, works good
enough" and they have to wade through dozens of useless responses to
_maybe_ get one that's worthwhile.

Welcome to rraa, where no one "important" ever agrees.

Hi Tom,

old gent.

Haven't seen him since roughly the new year. His protege is back though.
