Doublet Antenna question
No time to read all the other posts, but in short...
You are proposing a slightly shorter than 1/2 wave dipole for 75. This
should be no problem as it will have a little capacitive reactance and a
tuner should handle it.
The G5RV is pretty much the same thing, except it has some feed line
gymnastics to get a "fairly good" (50 ohm) match on many bands. This is
nothing more than an "antenna tuner in feed line" which doesn't require a
knob rather than one in a box which does. (:-)
My 40M dipole works on 30M as a slightly LONG dipole. [[ It also works on
75 as a really short one, but not too good]]

It turns out that it becomes quite challenging to implement an
efficient feed system (especially over a wide frequency range) where
the dipole is less than about 35% of a wavelength at the lowest
frequency.
Yes, my 100 foot length would be about 42% ofthe wavelength of my
lowest operating band, 75M.... perhaps it wouldn't be any problem for my
cheap MFJ balanced line tuner to feed it?
I appreciate your comments. I'm off shortly to study the website you
pointed me to. Thanks.
