- The T2FD antenna - Terminated Tilted Folded Dipole (Guy Atkins)
The terminated. tilted, folded dipole (T2FD) is a little known antenna that performs excellently. Compact in size it gives great signal gain, wide frequency coverage, and exceptionally low noise characteristics.

- Balancing - or not...
Amateurs are almost religious about balancing their antennas - in order to get the most power into, and out off, the antenna. But receiving antennas, do they really have to be balanced? Well, yes and no. It all depends... Read, and learn, more about this subject:
- Magnetic Longwire Balun
Instead of making your own balun you may buy a comercial one, such as the Magnetic Longwire Balun. It is practical, but is it worth it's steep price? No, most DXers agree. Several call it a rip-off. Read, and judge for yourself:

- The Carpet Loop II
An inexpensive, easily built, high performance antenna that can work in almost all apartments.

- Make it cheap, simple and effective
Modern shortwave receivers, especially portables, most often are
intolerant of overly strong signals. Therefore, the best, and least costly, antenna is the least antenna that can receive what you want to receive.

- Field Test of MFJ-1026 Phasing Unit.
The unit has unacceptable high losses in the lower medium wave band. This is easily fixed with a diagonal cutter - at the same time throwing warranty coverage to the wind...
But once the MFJ-1026 is modified, it makes a very competent phasing
unit that will undoubtedly bring the technology into the hands of
many DXers who have not previously experienced its value in
bringing new stations out of "the mud".

- Simple high-pass filter to cut off disturbing signals.
Having a lot of strong local medium wave stations around? Then you need a high-pass filter to cut off signals below, say, 2 MHz.

- Improve Sony 2010 reception with antenna matching device.
There is significant impedance mismatch between most shortwave antennas and the receiver. With this antenna matching device you will get maximum signal to the receiver at most frequencies.
