80 Meter Half Square Antenna

If you want a good, effective DX antenna for the 80 meter Amateur Radio Band, then please consider this Half Square Antenna from Don Johnson (N4DJ).

According to Don, this antenna offers a bi-directional low-angle signal launch using readily available materials.

Here are some comment from Don:

My 80 meter bent half square was probably the best antenna I ever had. I had it broadside to Europe at my Hampton Va QTH, I had it broadside to the Pacific area for one contest at my New Kent location and then installed it again broadside to Europe. Very hard to work Europe off the ends so I took about 5 hours to rotate it. Only rotated it once! It is important to note that a half square is not worth the trouble on 20 meters and above because a dipole at the same height as the top wire of the half square has more gain for DX. On 40 meters the top wire is about 35 or 40 feet and a 40 meter dipole at that height is about the same as the half square and a dipole is easier to put up.
