Fixing my noise floor with a loop for receive at AI7R

[@johnwest7993]

A mag-loop, especially a tunable one with a high Q is great for reception, and not bad on transmit either. But you either have to keep the power down or build the antenna for high currents in the loop, and high voltage in the capacitor. It doesn't even have to be all that high in the air, just in the clear and 6 feet or so above the ground, as the magnetic field interacts noticeably less with the ground than the electric field does. Yours is perfect. On receive you can conveniently even play with 2 of them and phase them and rotate them so that you can minimize noise with one and maximize reception with the other. Antenna phasing is one of the most fun and effective aspects of radio, but few hams bother with it because with E field antennas It's a lot of work and takes a lot of real estate. But with mag-loops it's small, works relatively close together, and they are cheap and easy to play with. I suspect they are the future of ham radio as fewer and fewer hams have a house and property that keep the neighbor's RFI at a distance and allows for big vertical arrays. Mag-loops really are the answer to noise and for directionality on HF.
