brand new and high quality. Features: This is a super portable passive HF/VHF loop antenna designed for super low NF/MDS receivers like the Airspy HF+ Discovery. It also works to some extent with the RTL-SDR V3 in direct sampling mode if you enable RTL AGC. But for radios without super low MDS specs, the signals can be boosted on by using any external low cost HF amplifier, or even our wideband LNA. This antenna is designed for portable use and is not weatherproof. Permanent mounting can be achieved with weatherproofing tape. Passive design, no tuning required. Low loss broadband BALUN, typical loss is 0.28 dB. Magnetic Antenna Kit only, other accessories demo in the picture is not included.
