Do you have a problem with a high noise floor on HF due to local interference? We did here at Omni RF HQ until I found the excellent Loop On Ground design by KK5JY which totally transformed the receive side of our station. The S9+10dB of noise on 80 meters vanished and was replaced by cleaner signals with an SNR improvement of between 3 to 6dB.
The Loop On Ground (LOG) antenna is made in its original design from a 15′ x 15′ square of wire laid on the ground, fed via an isolated ferrite transformer and connected to a receiver with coax cable. While testing, we found that the original 15′ x 15′ version works well on 30 meters and up and a larger version made from a 25′ x 25′ square works better on the lower bands like 40, 60, 80 and 160 meters.
This Omni RF version of the Loop On Ground Transformer uses a different core to the original design, which provides less loss and higher performance on the lower bands. We use genuine Fair-Rite cores wound with enamelled copper wire and a custom turn ratio that produces the best results after 6 months of testing. The enclosure is custom 3D printed in ASA, a high-quality ABS-type material with superior UV resistance, and comes with a galvanised steel ground peg for installation on soft ground.
All the nuts and bolts are marine-grade Stainless Steel with wing nuts for the loop connection to allow an easy install, and high-quality coax connectors are used on all versions.
The internal PCB has several additional jumpers to allow for simple future expansion with our add-on boards, such as the Active Pre-amplifier (coming soon), AM Broadcast Band Filter (coming soon) or the Experimenter Board (coming soon). We also apply a solderable conformal coating to the PCB to help protect the components from the elements while still allowing for easy repair or modification.
Supplied in 100% compostable and environmentally friendly retail packaging containing:
- Loop On Ground Transformer (Version indicated on packaging)

Please note that all products are handmade.
