New HF Antenna = Roomcap


Before, all antennas were built accordingly the principle: Current in wire.            This antenna is working with this principle: Current over planes, this is a open capacitor. (The first ROOMCAP antennas were using a thick tube, as I was seeing, that a large surface gave high efficiency. Then I changed to grid plane, there the surface is greater).

Therefore, the efficiency of this antenna is very high, with a efficiency as a large wire antenna of half wave length, while the radiator has size of only 1m x 1m!
