The MFJ-1886 Receive Loop is a powerful tool for copying weak stations amidst high levels of QRN or QRM. It covers a wide frequency range from AM broadcast to 30 MHz and beyond. The loop's superbly directive element and low-noise preamplifier allow for the retrieval of buried signals that are typically lost with wire antennas. The loop offers the perfect balance for deep nulls, dual-MMIC push-pull pre-amplification for a wide dynamic range, and an indestructible aircraft-grade 36-inch aluminium loop. It is lightweight, portable, and can be easily mounted using standard TV-style hardware. The weatherproof enclosure allows for outdoor installation, and the loop can be permanently mounted on a TV rotor or installed on a tripod or handheld mast for portable use.

The MFJ-1886's superior performance is attributed to its balanced-input preamplifier. Dual MMICs operating in push-pull provide an extremely low noise floor and a wide dynamic range to handle overload from nearby transmitters. This results in a crystal clear reception of weak signals and immunity from IMD. The loop's high-gain amplification and push-pull symmetry ensure deep nulls and accurate directivity.

Installing the MFJ-1886 is fast and simple. It can be mounted on any conventional mast using standard U-bolts, and all mounting hardware is provided. The loop's preamplifier is phantom-powered through a coax, eliminating the need for external wiring in remote installations. The loop comes with the necessary Bias-T and plug-in AC supply, or any external 12-volt DC source can be used for portable setups. A 50-ohm feedline with PL-259 connectors is required to connect the loop, along with a short PL-259 jumper to connect the radio to the Bias-T. Everything needed for installation is included.

With increasing interference from consumer devices and digital systems, the MFJ-1886 receive loop is a valuable tool for locating and suppressing noise sources. It allows for a more enjoyable operating experience by nulling out unwanted signals.
