Active Magnetic Loops for low-noise receive

Rx only active magnetic loop antennas

Join us on Sunday 7 June via Zoom to hear Bernard ZL2BD’s shed workshop talk on active RX magnetic loops.

Magnetic Loop Antennas in general have encountered a resurgence recently for Amateur Radio. A key attribute that seems to have been rediscovered by many is the small physical size of antennas for the 3.5 – 30 MHz HF bands. This makes them an attractive solution particularly in urban environments where space for antennas is quite restricted. Another important attribute is the improved signal to noise performance on receive compared to larger conventional wire antennas.

Using an Active Mag loop receive-only antenna is another variation of Mag Loops that provides the benefits of a low-noise receiving system without having to meet the stringent low ohms loop and high voltage tuning capacitor that is required for transmitting.

The shed talk using Zoom on Sunday 7 June will discuss construction of Active Mag Loops.
