Comparing 20m antennas

Solarcon A99 vs 10m long end fed wire (sloping down from base of A99).



A99 is 6dB down on transmit and 6dB up on receive (as long as noise level and M6AYY's antenna stayed the same). Both tests were done around the same time of day and the distance is short enough to make sure the propagation isn't going to change.

The SWR without a tuner of the A99 is very high (>5:1) but the LDG AT-7000 autotuner handles it OK.
