The ATL-3 Loop Antenna

  
All ATL-3 loop windings are centre tapped and balanced w.r.t. their amplifier/receiver chassis ground, and therefore electric field interference pick up tends to self cancel. Magnetic noise fields,e.g. televisions and the electric meter box, or electromagnetically radiated interferences, may be minimised by loop rotation.

Where the received noise does not degrade wanted station reception, an indoor active loop can be very rewarding. Tuned winding antennas always have a potential 6dB greater signal sensitivity, and provide a better signal to noise ratio than equally size
