Omni RF Loop On Ground RX Antenna Kit

Hear more and fight less noise. This complete receive-only HF antenna kit is for radio amateurs, DXers, and shortwave listeners who want lower noise pickup and improved weak-signal readability. It combines the purpose-built SO239 50 ohm transformer with the matching pre-terminated loop element for a practical, discreet, and easy-to-install ground-mounted receiving antenna that suits city lots, smaller gardens, and stealth-focused installations.

Overview

The Omni RF Loop On Ground Receive Antenna Kit combines the dedicated LOG transformer and matching wire element into one complete antenna. The design is based on the well-known Loop On Ground concept, using a wire loop laid directly on the ground and fed through an isolated ferrite transformer to deliver quieter HF reception. The Omni Flex element is available in two sizes: 18.3 m total loop length with 4.6 m per side, or 30.5 m total loop length with 7.6 m per side. The smaller version follows the original-style layout, while the larger version is better suited to lower bands. The transformer uses genuine Fair-Rite cores, enamelled copper wire, a custom turn ratio, stainless hardware, and a UV-resistant ASA enclosure. The Omni Flex element uses finely stranded pure copper wire with low-memory black polyolefin insulation for easy deployment and long service life.

Key Features

• Complete Loop On Ground receive antenna kit with transformer and wire element
• Receive-only design for reduced local noise pickup on HF
• 50 ohm system design with SO239 UHF connector
• Choose between 18.3 m total loop length with 4.6 m per side or 30.5 m total loop length with 7.6 m per side
• Omni Flex element made from 22-strand pure copper wire with 0.75 mm conductor size
• Flexible zero-halogen polyolefin insulation with very low memory effect
• Rated for use from -25 to +90 °C [-13 to +194 °F]
• Genuine Fair-Rite transformer core for low-loss performance, especially on lower bands
• ASA enclosure with galvanised steel mounting peg for outdoor use
• A2 stainless steel hardware and wing-nut element connections for simple installation
• Low visual impact for discreet home, portable, or field receiving setups

Typical applications

This receive antenna kit is ideal for HF DX listening, contest receive improvement, low-band listening, shortwave monitoring, and amateur radio stations suffering from elevated local noise on transmit antennas. It is especially attractive for operators on city lots, in suburban gardens, or in stealth-focused locations where a full-size raised receive antenna may be impractical or too visible. Because the loop sits directly on the ground, it can often be installed with minimal visual impact and without drawing attention from neighbors or visitors.

Setup Guidance

Choose the 18.3 m version when you want the smaller original-style layout, typically installed as an approximately 4.6 x 4.6 m square. Choose the 30.5 m version when you want the larger layout, typically installed as an approximately 7.6 x 7.6 m square, which is generally better suited to the lower bands.

For best results, deploy the loop directly on the ground in as square a shape as your space allows. A square Loop On Ground fed at one corner can show a broad directional preference at low angles, but the exact pattern depends on loop symmetry, ground conditions, nearby structures, and frequency. In practice, the best approach is to rotate the square and compare signal-to-noise ratio on your target signals. Keep the loop symmetrical, avoid routing the feedline alongside the loop, and keep the feedline away from household noise sources where possible.

Adding a good-quality common mode choke at the feedline can help reduce unwanted noise currents on the coax shield. In lower-signal setups or where you need extra gain to overcome coax loss or receiver limitations, a low-noise receive preamp can also be beneficial.

Choose the Omni RF Loop On Ground Receive Antenna Kit when you want a cleaner listening experience, a tidy installation, and a complete ready-to-deploy package for serious HF receiving. It is a smart upgrade for any operator who knows that hearing more often starts with lowering the noise floor, especially when available space is limited and antenna visibility needs to stay low.
