Gene,either antenna will fit into your yard without a problem, but don't get
locked into the idea that these are your only options, just because a lot of
other folks use them. That's not to say that either antenna wouldn't do a
good job for you; you just have more options.

If you run either antenna, feed with 450-ohm ladder line (look for the stuff
with stranded wire - it holdsup better in the wind. And, 450-ohm line tends
to tune a bit wider than 300-ohm. Forget the auto tuner, and use a good
external tuner - you'll get much better results.

Good luck with your upgrade...

I have an 80x100 foot lot. On a diagonal between trees I could put up a
flattop of 102 feet. Should I put up a G5RV or bend the wire at each end
and
go for a 135 foot center fed? My rig is a TS-440S with a built in tuner.
What type of feed do you recommend. Some say you get the least loss with
twin lead. Should I use 300 or 450 ohm? Then should I put an air choke
at
the end of the run and tie the other end of the air choke directly into
the
rig's auto tuner? Also should I install a lightning arrestor at the point
where the feed enters the house (I'll probably drop the feed to the roof
and
bring it into the attic. The shack is in a second floor bedroom.) I am
presently studying for my license so any advice would be greatly
appreciated.



Thanks,
