Figure 8  Antenna UA6AGW V.20.0

 

Coupling loop for the Antenna UA6AGW V.20.0  may be made similar to the coupling loop from Reference 1. However, perimeter of the coupling loop should be decreased to 800- mm. The antenna was installed at the height of 8- meter above the ground. Antenna UA6AGW V.20.0 was compared with an antenna G5RV that was installed at 21- meter above the ground.  It was used a transceiver TS870S with testing of the antennas. Igor wrote about the testing: At the Mode JT65A (software JT65-HF) the antenna UA6AGW V.20.0 allowed me to work with South Africa- 18- dB, Far East– 12- dB, Australia- 15- dB. Antenna G5RV received those territories much worst. Antenna UA6AGW V.20.0 is low noise antenna. The antenna could gain in direction (when it rotated) up to 5… 10- dB, sometimes up to 15- dB.
