Snip

You mean Tilted Terminated Folded Dipole (T2FD)?

http://en.wikipedia.org/wiki/T2FD_Antenna

Hi Telamon,

It started out as a tilted dipole, but I didn't have enough height in
the attic, so RHF suggested that I twist it around about it's axis. It
works very nice, but still some noise from all the electronic gadgets
in the house. In the fall I will stick a long wire across the river in
the way back.


Nothing wrong with the dipole being horizontal instead of tilted. I do
not think twisting it is a great idea but it looks like it works OK.

Hi Telamon,

Did you simulate it?

It seems to work very nice, but I don't have a lot of experience with
too many swl antennas. as I said already, RHF suggested the twist.
I'm not sure if he had simulated or not.


No I don't simulate antennas. Antennas follow basic rules and usually
all you have to do is apply some logic. I don't see any advantage to
twisting a folded dipole other than shorting the physical space need for
one cut to some frequency. Coiling elements generally causes them to be
less effective on receive so I don't expect doing so would result in an
improvement. If you can fit a folded dipole in the space you have cut to
the lowest frequency you want to receive then there is no reason to
twist it.
