Stan,
Thanks for the praise! I wish I would have the same RX capabilities as TX, but
my limited sized rock wont allow for it. Right now I have two pennants, one in
NW and the other in NE plus a 50 meter BOG in N-S with can be reversed in
direction but mainly for AF. Fortunately it is rural so
Björn,
I would like to see your picture if you could send it to me. You are always
strong on 160 and now we know why.
For the verticals I have put up on a temporary basis very close to the water, I
am pleased with just two elevated radials. I tried radials on the ground and

My 160m antenna history:
1. (1980-1995) from central Ohio loading a 130 ft long qtr wave sloper
off a 60 ft tower: Never loaded well, but worked KP4 and a couple
others. No Euros or significant DX. ( I was a contester focusing on
10-80m.) So a couple of mults on 160 made me happy.
2. Moved to a
I wanted to shorten my inverted vee for 160 the other day. The initial setup
resonated at 1740 , and sat that way since last year ( medical pblm). I cut off
6ft and went to measure in the shack and it wound up at 1630. I realized
something was afoot, and figured maybe the coax went bad. Went

Same bad news here in West Michigan. 3/4 ice toppled the 60' mast holding
my inv V that had been up for the last 12 years, and also brought down one leg
of the T xmit antenna with other leg drooping badly. I still have 1/2 ice
coating the vertical section and it won't tune. It may get up
I have been following this thread with great interest. Though I don't have or
plan to have a vertical such as a GAP or Butternut, I have found all the
information very enlightening, particularly everything about radial fields.
Keep at 'er guys!

Hi Tom,
I am suprised that no one has brought up the T2FD antenna and
of course the BW All-Band antenna.
It was in one of the magazines back in the (50s?).

Price, The Military and U.S. Embassies use T2FD type of antennas all
over their deployment perhaps due to the fact that they do work as long
as you have plenty of horsepower to feed them with. I think the
requirement of frequency agility for their requirement outweighs the
inherent
waste a
lot of others time with their views.

T2FD I though came out around in the Navy since 1940.
It is -5 db down from a dipole. Shortened versions past and present are still
-5db down from what I have been told. They are very good antennas for emergency
stations.
Stay on course, fight a good fight, and keep the faith. Jim
angle is less critical and can be 20-40 degrees.

The T2FD was described in QST for June 1949
The so called T2FD's sold these days by the usual ham dealer suspects is
nowhere near the original design so its no stretch as to why its not a
great
performer.
Any antenna that increases bandwidth through a resistive termination will
always lose a substantial portion of power as heat on
It is great to see the technical discussion regarding topband antennas,
particularly the FCP. Thanks to K2AV for putting his ideas and design out
there for peer review. Hopefully the review process won't discourage folks
like myself, who are not antenna enginers, from trying various ideas
With all due respect:
The FCP is a dipole. One end is vertical while the other is weaved horizontal
on or near the ground.
The 1:1 isolation Trasformer / Balun serves its purpose as well as stopping
those nasty common mode
conditions.
The FP and CY9 came on and I was not able to work them
The FPC Isolation Trasformer / Balun I am suspecting has a loss about 2 DB a
little more loss than a non isolated balun. Has any one ran any data on this?
Stay on course, fight a good fight, and keep the faith. Jim K9TF/WA9YSD

Wow, I thought this reflector was for topics pertaining to
Top-Band. I for one have enjoyed the lively exchange of
ideas and views in the recent radial exchange. I do believe
that something was gained for top-band as a result.
Exactly what this reflector is for. I took a moment and
