Description
New Improved Active Short-wave Small Loop Antenna Board PCB for SDR SW HAM Radio Receiver
Description：
Compared with the previous generation, it has wider bandwidth, more power saving, better working stability and better dynamic range. Super version of diy ring antenna amplifier
Do not touch metal conductive objects to prevent short circuit damage to the circuit board. The output terminal must use a shielded coaxial feeder, otherwise it will self-excite.
Small loop antenna Yuanfang antenna Super version of the same plan Improved version of the radio antenna SDR antenna Active short-wave antenna
1. The battery's power supply line adopts perforated design, which is more firm and not easy to break the thread. There are hoisting holes on the top and bottom, which is more convenient for both upside down and formal installation.
2. The super version chip adopts 14pin chip, which has higher sensitivity and more power saving. It is powered by a 9v square battery and is shipped without battery.
3. This antenna is suitable for players with radios, receivers and SDRs with external antenna input ports. It is mainly used for shortwave reception and transmission is prohibited. The kit or finished product is shipped without batteries.
