Impedance Matching: The high-resistance amplifier serves as an impedance conversion device, effectively matching higher antenna impedances to a standard 50-ohm output. This ensures optimal signal reception and minimizes energy loss due to impedance mismatches.\u003cbr\u003e2. Wide Compatibility: Compatible with various radio receivers, SDRs, transceivers, and more, such as PeaCock, Mini Loop, HackRF One, and Donut antennas. It can enhance the performance of your receiving equipment by maximizing energy capture from input antennas.\u003cbr\u003e3. Direct Connection to LC Resonant Antennas: This amplifier can be directly connected to LC resonant antennas, including loop antennas like the Donut antenna and magnetic bar antennas. It extracts energy directly from these resonant antennas, offering higher gain and selective frequency characteristics.\u003cbr\u003e4. Long Operating Time: With an 800mAH built-in battery, this amplifier provides an extended operating time of over 24 hours, ensuring uninterrupted use during extended listening sessions or fieldwork.\u003cbr\u003e5. Compact and Portable: The amplifier's compact dimensions (50x45x18mm) make it highly portable and easy to integrate into your radio setup. It's an ideal companion for outdoor enthusiasts and radio hobbyists.\u003c\/p\u003e\u003cp\u003e\u003cbr\u003e\u003c\/p\u003e\u003cp\u003e\u003cspan style=\"font-weight: 700;\"\u003e\u003cspan style=\"font-size: 18px;\"\u003ePackage Include:\u003c\/span\u003e\u003c\/span\u003e  \u003c\/p\u003e\u003cp\u003e1x High Impedance Amplifier\u003cbr\u003e1x Donut Short Wave\u003cbr\u003e1x Donut Medium Wave\u003c\/p\u003e","brand":"LinkMejor","offers":[{"title":"Default Title","offer_id":49120515358945,"sku":"BG-1997437","price":29.69,"currency_code":"HKD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0853\/9317\/8849\/files\/b7a5f7d9-5563-44b1-9b58-9ab484765d8e.jpg?v=1789396731","url":"https:\/\/ontproduct.com\/products\/donut-am-mw-sw-mini-loop-antenna-high-resistance-amplifier-kit-for-hfdy-malahiteam-dsp-dsp2-receiver-hf-middle-wave","provider":"IvySource","version":"1.0","type":"link"}
