Basic question
Why is it that my radios are 50 ohms and the impedance at the feed
point at
the antenna (pure dipole) is 70 ohms.
No, yer not mistaken.... but, if you want to lower the input impedance
to your dipole, bring the legs down to around 40 degrees, and you'll
drop the input impedance to the antenna down around 20 ohms.

Geoff, Alan, Et al,
Both of you are RIGHT - BUT - almost EVERY radio/amplifier will tune
from 50 ohms to about 75 ohms.
So futzing with the antenna MAY not be NEEDED!
I didn't say he -had- to. I just made the suggestion, if he -wanted- to ;-)
