https://stream.echo6.co/videos/watch/36176504-1bbb-40bb-8824-60b7618795c3 Testing a 30m perimeter rectangular loop antenna. It is a full wavelength on 10 MHz and 3/4 wavelength on 7 MHz. Feeding is with slotted ribbon feedline with a balanced antenna coupler. I transmit WSPR bursts with it being vertically polarised and horizontally polarised. Then I compare the reports received via WSPRnet. There are some substantial differences when I change the antenna's polarisation by moving the location where the loop is fed.
