Superloop III Antenna


The Superloop is the 30' length of ladderline hanging down from the center insulator. This length has been tuned so that appears to be a open circuit stub on 40 meters; thus the antenna becomes two full wave wires at 40 meters and is commonly referred to as the Bi Square antenna

40 Meter Parasitic Delta Loop Array
On 40 meters, my experience is that you need at least 20 dB of F/B ratio in order to be able to turn down European broadcasters enough to be able to hear the west coast stations, especially the west coast stations with dipoles and 100 watts

Delta Loop per 50 Mhz
we will use the formula: L = 306.6 / F Mhz = 306.6 / 50.150 = 6.11 m. in practice we will have that each of the three sides will measure 2.04 m

Delta loop various configurations
The wave emitted by the vertical loopmay be polarized vertical or horizontaldepending on the feedpoint location vertical polarization is preferred when the antenna is low
