How good is your #hamRadio antenna?
One way of finding out is to compare it with another antenna. WSPR is a good tool for that: Transmit on both antennas simultaneously and see which antenna other people receive louder.
We did that with a rather low-hanging shortened EFHW and my upper and outer. Result: On 20 m, my U+O was received with 4.6 dB less SNR on average, but on 40 m, the dipole was 3.5 dB better.
On reception, the dipole was better on both bands.

An antenna comparisonSummary An end-fed half wave antenna that Thomas Riedle, DD4TR brought was compared with an upper and outer antenna by me, DJ3EI, on the 20 m band and on the 40 m band. I thank Thomas for allowing me
