[Elecraft] Folded Dipole Antennas

I agree with this!  We tried using these in coast station SSB marine service and they
are troublesome antennas, very inefficient.

| Edmund,
|
| the B&W folded dipole achieves the wide bandwidth through a lossy termination. The
radiation efficiency is about 30% max at 40 meters and above. I have analyzed this
antenna and designed a monopole version of it (see AntenneX magazine 2 years ago).
The Alpha Delta appears to be a number of parallel dipoles. While these don't provide
a great match, an antenna tuner is part of the installation and will make it work
well. The Alpha Delta should be roughly 4-6 dB above the B&W.

| I am trying to choose between a Barker & Williamson Broadband Folded Dipole antenna
BWD-1.8-30 and an Alpha Delta Shortened Multibander DX-CC for my K2.
|
| Does anyone have any experience with either of these antennas that could help me
decide?
