Default feeding random inverted V for RX

What do you REALLY want?

73's
Richard Clark, KB7QHC


Dear Richard,

My question is very simple:

I'd cut a dipole of about 15 + 15 m (50+50 ft), 120 deg. inverted V,
apex at 15 m.
I could do 1:4 - 300 ohm or 1:9 - 625 ohm.
What would be the least-bad?


If you can't or won't tell if such an antenna very roughly better
matches a 300 or 600+ ohm source over the HF spectrum,, what else
can I do but
- turn on EZNEC and start playing
- build two or more transformers and send someone up at the 50ft apex
and swap them in sequence while I do in vivo comparisons and pollute
the spectrum
- wait for someone else to answer or to point me to a good URI?

I can live with it.

I might also put together the rather long list of authors of articles
on the subject and ask them on your behalf what they really really
want if they have to feed the thing with a coax instead of ladder
lines of the commercially available impedances and want the least
lossy solution among the available alternatives. :-)

73 es tnx de n1jpr/i2
