Joe,
Forgetting about RF performance for a moment, wouldn't the weight of RG-8/
RG-213 create a problem unless the antenna is supported at its feedpoint ?
If it is not supported, Don could end up with an inverted inverted V, aka a
Droopy Dipole.
BTW I do not use the plastic window/ ladder
Can anyone suggest a compact balanced line that can handle 1000 watts? I like
the size of that Radio Shack 300 ohm TV line, but 100 watts is likely the
maximum. I'd like to build a stealthy KW antenna. The 20m dipole radiating
elements are so low to the ground that 3:1 SWR is the best I can

I know it doesn't answer the question you asked, but RG-8/RG-213 has a
loss of about 0.85 dB/100 ft at 20m. Your 3:1 SWR will add a little
less than 0.4 dB additional loss for a total loss of 1.25 dB. Is the
added hassle of running balanced line worth the extra 1.1 dB? Are
there other
ohm line, and it is so much easier to work with. FWIW, I recommend it.
