Diamond antenna SX400 SWR meter for 140-525 MHz bands. The SX-400 is an insertion type SWR / Power meter being connected between a transmitter and an antenna. Transmitting power and SWR can be measured with very simple operations.
In addition with those conventional measurement, PEP (peak envelope power) on SSB mode can be measured with a PEP monitor function. With our DIAMOND's wideband and low insertion loss directional coupler those measurements can be performed with minimum effect in transmission line.
