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. -- Telamon Ventura, California 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. -- Telamon Ventura, California Ok...I misunderstood you. I thought you were talking about the MTA instead of the T2FD. |
