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.

Steve

It's worth noting that RF Systems has a much better website than they
had the last time I looked:

You can trace the folded dipole element in the picture. It starts at the
coax connection and at the top of that spreader is where the ~ 600 ohm
termination resistor is located. It's a low noise antenna because it is
a loop type antenna that is not as sensitive as a open dipole to local
noise fields.
