Anyone have a website address for the R.F. Systems that
makes SW
antennas sold by Universal Radio
Yes, its: htttp://www.rf-systems.nl
Steve, thanks for the good word on the MTA, I've been
waiting to save enough to buy one, and I'll be ordering it
in a week or so.
I once had their old version T2FD for a few years. A
complete lack of noise makes shortwave radio listening and
dxing a wonderful experience.
The old one was rated for use from 5-30 MHz, but I was
listening (not just detecting) low powered Africans into
the 90 meter band. The new version is rated down to 3 MHz
but I don't have the space to put one up anymore or I'd be
able to tell you the difference.
Do us a favor and post a detailed review of this antenna
after you've used it for a while, describing where you have
it mounted and how it's grounded.
It is a balanced antenna so no ground needed.

Hmmm. I didn't realize that, but I guess it's true of many, if
not all, RF-Systems antennas. Do you know how the balance is
achieved? I know there's a helically wound antenna element on the
inside...I figured it was just fed at one end.
T2FD - Tilted, Terminated Folded Dipole.
Basically a folded dipole antenna with a termination resistor for
transmit loading and most likely no better for receiving than a
horizontal positioned folded dipole for receiving.
A dipole or a folded dipole is a balanced hertzian antenna where no
ground is needed for it to operate unlike a single wire antenna
where the other half of the antenna is ground.

Ok...I misunderstood you. I thought you were talking about the MTA
instead of the T2FD.
Sorry about that, I didn't notice the other one (MTA) just the T2FD.
The T2FD will be a much better antenna.
