Product: Loop shortwave active receiving antenna Compatible with: UHF, VHF, FM and HFDY DSP2; also suitable for all FM radios Key benefits Better reception in difficult conditions: boosts weak shortwave signals and helps overcome strong electromagnetic interference to deliver clearer audio and more reliable reception. Wide compatibility: works with shortwave, UHF, VHF and FM receivers and is explicitly compatible with the HFDY DSP2 model. Portable and convenient: compact, pocket-size active loop design makes it easy to carry for travel and outdoor listening. What it does Enhances signal strength and stability when your radio’s built-in antenna underperforms. Uses two design features to improve overall reception performance for shortwave and FM radios, helping you get clearer stations and fewer dropouts. Active loop operation increases sensitivity in noisy or low-signal environments. Key attributes Function: Active loop shortwave receiving antenna that amplifies and stabilizes incoming signals. Compatibility: UHF, VHF, FM, shortwave receivers; specifically suitable for HFDY DSP2 and compatible with all FM radios. Size: Pocket-size portable unit designed for easy transport and outdoor use. Performance: Improves reception in areas with weak signals or high electromagnetic interference. Practical use scenarios Travel and camping: Carry the pocket-size antenna to remote locations where built-in radio antennas struggle to pick up distant stations. Urban environments with interference: Use it at home in apartments or offices with high electrical noise to reduce static and improve station clarity. DX listening and hobbyist use: Attach to shortwave and FM receivers (including HFDY DSP2) to enhance long-distance station pickup and listening sessions. What to expect Easier station tuning and improved listening quality when your radio’s reception is poor. Simple, portable solution to improve shortwave, VHF/UHF and FM reception without major equipment changes. Note Retains full compatibility with HFDY DSP2 and general FM radios as stated.
