Neither. I was suggesting (and obviously not very well) that you use it
as a receiving antenna. It's very low noise. It makes a good transmitting
antenna too, but you need to have a big enough balun and termination
resistor to handle the power.

This could be a very interesting experiment. Try the
T2FD but in steps.

1. Ordinary horizontal single-wire dipole

2. Ordinary horizontal folded dipole

3. T2FD

Reporting the noise on those three configurations
vs the vertical would be of wide interest.


well, I already use a shortened dipole which has one leg at 45 degrees (the
end is somewhere between 2.5 to 4 ft high, I have not measured it)
to the feed point that is about 2 to 3 inches off the ground and the other
leg is about 1 to 2 inches off the ground.

I don't use it directly into the receiver, I suppose I could, but I use the
Timewave ANC-4 for reducing noise and its my noise sense antenna.

Obviously this one as I mentioned works extremely well on 40 meters, I can
null out all noise, the S meter lays flat on S1, but the 80 meter
performance is poor.

I would like to try the other antennas you mentioned as sense antennas, the
problem is do I go full size on the folded dipole? I think I need to go full
size with the T2FD in order to get it to work correctly.

How high above ground do I need to get it?
