thanks for the encouraging words Curt. So you have my interest so on the
ground connect the two ladder lines and then put out radials to just the
ground lead on the ladder line or both?

Ham radio discussion always welcome. Do remember that Ray is an enthusiastic
new ham, and he is learning fast.
I may have expressed some doubt on his G5RV on 10m - and Ray proceeded to
work a ZL!
Cool story on those mountain people (like me except I got stuck growing up
in Cleveland).
Actually that 102 foot doublet could work pretty well on topband - with a
little imagination. As it is extremely high - if Ray would attach the two
ladder line connections to a common point - and feed it against some ground
radials - he would have a nifty top loaded vertical. Of course that can wait
until next fall now that we are into Spring QRN. (Some how I have 60-some
countries on topband with a 36 foot vertical radiator).

Just for information a 102 ft dipole will not perform too well (even if you
can load/match it with a tuner). Reason? It is way too short to be a
productive antenna
on TB and you may be able to work some very local stations but much more
than 200-300 miles out will put you at a serious disadvantage. The other
thing is.. put the rope on the center of the dipole and get it as high as
you can.. then support the ends at whatever height you can.. dont forget to
take into consideration the sway of the trees so dont make it too tight that
it breaks in the first wind storm
RE Ladder line - in the old days before cable TV the mountian folk used to
put their TV antennas up on the top of the local mountian and run homebrew
(yes homebrew) open wire feeder up the mountian. This was often 2,3 or even
4000 ft of wire. Quite often they used the wire they had on hand which
mostly was electric fence wire made of either hard drawn aluminum or
galvanized wire. Usually this was such an undertaking that a group of
families got together and put one antenna up for several households.. they
just tapped off the open wire feedline at whatever location was convienient
and ran it into their house .. .then tied it to their TV set. There is very
little RF loss to true openwire line the losses are mostly ohmic in nature
(basically DC resistance). So it wasnt hard to put up 4000 ft and only have
a db or two of loss in the TV signal at the set.
Ohhh if you want to get on TB .. use an inverted L not a dipole that is if
you want to work DX.

P.S has anyone worked any of the wild DX this week during the solar storms?

Ladder line is good and it could be a mile and still usuable. But with that
length the line should use at least 14 AWG stranded wire. RFC has one that
is 390 ohm I use 125 feet here with a 141 foot dipole and it is easy to tune
10 through 80 but not as easy on 160 as the 256 foot offset windom.

Ray-
www.therfc.com is a good source for ladder line. He is in Gaithersburg.
