Delta Antenna for 80-. 40-, 20- and 15- meter Bands

 

Delta Antenna for 80-. 40-, 20- and 15- meter Bands: By: Nikolay Kudryavchenko, UR0GT

The Delta Antenna has perimeter 86- meter. Antenna has resonances at four amateur bands. There are 80, 40, 20 and 15 meter. However, input impedance at the bands not allows use a 50- Ohm coaxial cable to feed the antenna with low SWR at all the bands. Best solution is to use a 100- Ohm coaxial cable. Then simple ATU to match the antenna system with transceiver. ....
