Antenna Transmatch tuner Links →
Tuner in LC circuit
The tuner is connected to the transceiver via a coaxial cable and a SWR meter. Antenna and earth are connected directly to the tuner
Transmach 1,8 a 30 MHz eñado para las bandas de radio-aficionados
The transmach, is designed for radio-amateur bands, it is recommended, although it does not appear in the circuit, to place a 2.5 mH radio frequency shock at the output
Tuner 1,8-50
Variable capacitors and switch from R-104 BSN block. In the absence of these capacitors, it is possible to use 2 sections, from the transmission radios
