The build and test of a loop on the ground antenna for low-noise receiving on the lower amateur bands. This is a design by KK5JY and the full technical details can be found at KK5JY.NET
The idea behind the design is to have a low noise receive antenna when working what can be very noisy low frequency amateur bands. Transmitting on the main antenna while receiving on the ground loop.
This is my build and test of this design. See how I get on...
The Fair-Rite binocular ferrite core can be sourced at Mouser (No. 623-2873000202). Also at Qubits in the UK (radio-store.co.uk/). Beware p&p costs!
Ferrite Toroid 73 Multi-Aperture Z=1250 Ohms @ 10MHz.
Parts 2, 3 & 4 of this series, where more tests are undertaken and better results found, can be seen at:
