1-30 Mhz Manual Antenna Tuner kit for HAM RADIO QRP DIY Kit. Days can tune to the original non-resonant antenna by adding the appropriate inductance or capacitance so that the radio can work properly. The original resonant antenna, the antenna has changed due to outside influences, the SWR can be amended. Can be used as a band-pass filter, the emission can reduce unnecessary radiation outside the band, the cross-modulation and interference-band receiver can be reduced again. Days tune kit comes with the standing wave directions, using a T-type topology network, shortwave 1-30MHz, can withstand the transmit power of 15W, the tuning range of approximately 40-300 ohms, can be very convenient for QRP communication, to ensure high efficiency radio transceiver in communication, but also allows you to fully enjoy the fun of DIY.
This kit requires some soldering electronic technology, will recognize the device, it will weld, the basic need debugging, as long as careful assembly according to package instructions can succeed. If the novice find weld on the error, intended to build the first not handle, please contact customer service personnel will get the appropriate technical guidance. This kit welding, making easy to understand, easier to learn, easy to use. Comes with standing instructions, Q9 type interface (such as the need to be self to M-type interface), using T-topology networks, QRP facilitate communication with the low-power transceiver shoes, frogs, octopus, etc.
Used to make transceiver and antenna valid match, meet your emission requirements, ensure a highly efficient radio communications. Key Features of this manual antenna turner: Days when exposed to direct transfer power: <20W Day tune tuning the input power: <3W Tuning indication: LED display Interface: Q9 type Operating frequency: 1-30MHz Antenna Interface: Q9 type Match the antenna impedance range: about: 30 300? Carrying RF power: less than 15W Tuning required RF power: less than 3W. This kit includes the original as follows.
