1 - 30MHz QRP Manual Antenna Tuner DIY Kit with SWR Stand Wave Ratio Indicator for Antenna Installation
Description:
- The antenna tuner can add appropriate inductors or capacitors to the previously non resonant antenna to enable the radio station to operate normally. It is possible to modify the SWR of an antenna that was originally resonant but has undergone changes due to external influences. It can serve as a bandpass filter, reducing unnecessary out of band radiation during transmission and reducing out of band cross modulation and interference during reception.
- This antenna tuner kit comes with a standing wave indicator and adopts a T-shaped topology network. It operates at shortwave 1-30MHz and can withstand a transmission power of 15W. The tuning range is about 40-300 ohms, making it very convenient for QRP communication, ensuring efficient radio transceiver communication, and also allowing you to fully enjoy the fun of DIY.
- This kit requires a certain foundation in electronic technology for welding.
