KK9A knows a lot more than I do, but I don't think "poor antenna" is the
main factor in this case. Lots of us get by with poor antennas. I run
100W to a 200-ft-long dipole, and I can run IF I pick my band correctly.
(Of course, I'm talking about CW and some SSB; I don't do RTTY.)
Yes, KK9A does know a lot more than you do. A resonant half-wave dipole
antenna is a very good match on odd harmonics and presents a VERY high
impedance a terrible match on even harmonics. A decent tuner can match
your 200 ft-long dipole on bands where it is NOT a very high impedance.
I agree that propagation could have been at play. By the end of RTTY RU,
20M might not have been jumping between W6 and W2, and 40M certainly
does sometimes go long.
