Long Quad antennas are very interesting family of the simple and at that time high gain antennas. The antennas may have 50 or 75- Ohm input impedance. Figure 1 and Figure 2 show design of some of the antennas for the 28- MHz band. Figure 3- Figure 12 show SWR and DD of the antennas.

The antennas may be made from wire in diameter 1- 3 mm or ever from a tube. Antennas made from the tube may be easy disassembled and assembled in the field. The antennas may be recalculated for other bands- for example for 6- m band.
