Good evening,
Actually a dipole with a 10 to 1 SWR through an antenna tuner (coupler) 
should radiate fine. The large horizontal loop antenna is non-resonant on 
the frequencies it's used on with a 4-1 balun and an antenna tuner, and it 
radiates and receives well.

The "no counterpoise antenna," which I am told is basically a zep, also 
requires a balun and antenna tuner and radiates well. I plan to make this my 
first antenna here at my new house so I can start checking into the 40-meter 
and 20-meter nets soon, so you'll hear how well it can work.

Subject: a day in the park

I spent yesterday afternoon with w9njy, running portable sitting at a picnic
table out in a park.  It was sunny and warm for us here, probably mid 60's.
We litterally threw a 55 foot dipole fed with 300 ohm line up in the trees.
Put it on a kx-3, and turned the radio on.  I worked w1aw-8 on 20 meter CW
using the internal battery power.  So that was 5 watts.
Then we added a 50 watt amp, 7 amp hour battery pack, and switched to a LDG
tuner.
Then just for grins we plugged in a mike.
Now the SWR with out the tuner on 10 was 10/1.  Shouldn't radiate even if we
can tune it.
Well we sat there until it was pitch dark.  Worked the contest on 10 15 and
20.
We made 60 contacts in maybe 2.5 hours.
Everything from Argentena to alaska to Japan.
By the end we were wearing the coats hoods and gloves that we brought along.
This will be a memory to keep in February.
We used a slingshot connected to a fishing line to make the path over the
tree limbs.  Then we disconnected the fishing line, pulled a rope over,
hooked the antenna to the line and pulled it up to the branch.  Did that on
each end and let the center hang.
