Unbelievable answers (really).
If someone asked if anyone was knowledgeable about contesting or say
eme, would you just answer yes or no? Or would you offer assistance to
the questioner?
My first ham antenna was a folded dipole for 40m. It was described in
my first ARRL Handbook as there were no nearby hams to ask and in 1958
there was no internet. TV twinlead was locally available so was easier
to make than one requiring coax. I soldered a PL-259 directly the
twinlead feedline and connected to my DX-35 (which loaded it FB even
with high SWR that, at age 14, I was unaware of).
For HF half-wave, center-fed, dipoles have been my favorite. Currently
have a 80/40M inverted-V (fan-style). Wire lengths slightly longer for
resonance than for horizontal dipole. Cut slightly longer than formula
(492/F) and trim until SWR matched. I have ends supported with nylon
cord over pulleys to lower for cutting.
