Delta Antenna for 80- 10 meter Band

Figure 2 Schematic of the ATU

It is possible use two good quality variable capacitors instead S1.1 with fixed capacitors and S1.3 with fixed capacitors. In this case it is very conveniently to tune the antenna inside the 80- 10 meters band. The antenna works well on the WARC bands.

Antenna may be used on the 160 meter Band. For this case the inductor L1 should have more turns to match the antenna on the band or antenna should have perimeter 160 meters. It is possible to use antenna with perimeter less 84 meters however on the low bands efficiency of the antenna is decreased.
