This listing is for a pre-assembled Loop on the Ground (LOTG) receive antenna transformer. The LOTG is a passive, ground-coupled antenna designed to provide a different reception profile than traditional elevated wires. It is often effective at reducing local electrical interference and atmospheric static, leading to a cleaner Signal-to-Noise (S/N) ratio.
1x Matching Transformer: Pre-built using a binocular-type core for efficient HF impedance matching, housed in a weather-resistant enclosure.
Integrated Common Mode Choke: Now includes a Type 31 Fair-Rite choke on the input. This prevents the coaxial feedline from acting as part of the antenna loop, ensuring the loop remains the primary signal source and further reducing unwanted noise.
4x Ground Pegs: Custom-designed to hold antenna wire flush to the surface.
2x Crimp Spade Connectors: For terminating your loop wire to the transformer terminals.
4x Cable Ties: For wire management and securing lead-ins.
Receive Only: This is a dedicated RX interface. Do not transmit through this unit; it is not designed for power handling and damage will occur.
Frequency Coverage: This interface works best for reception on the 80m, 40m, 30m, and 20m bands.
Installation: Mounts directly on the ground. Its low profile makes it an unobtrusive option for locations with space or visibility restrictions.
Requirements: You will need to provide your own length of insulated copper wire and a coaxial feedline.
NO WIRE INCLUDED: This sale is for the pre-made interface hardware only. For optimal performance, a total wire length of 18.2m (laid out as a 4.55m square) is recommended.
Connection: Output is via a standard SO-239 connector.
A straightforward, pre-assembled solution for operators looking to utilize a low-noise HF receive antenna.
Type 31 choke, isolating the feeder, usually the "secret sauce" for getting these loops to perform as they should.
