Magnetic loop antennas can be very effective, small, antennas. They work well and are ideal for modes like WSPR, JT65, JT9-1 and PSK31 where frequencies don’t have to be moved much. Their main disadvantage is they are narrow-band so require retuning if moving very far in frequency and they are directional.
As ever, Steve G1KQH has been tracking down bargains – in this case motors that could be used to either tune or rotate loops.
