30 - 512 MHz

The TA3925M from COJOT is a tunable antenna with a steel whip radiator for the 30 to 512 MHz frequency band with optimized performace for the 30-90 MHz and 225-450 MHz bands. This low profile antenna can be tuned by remote control to use the optimum matching circuitry at the required frequency. It thus provides superior gain performance over traditionally matched wideband antennas. The extremely fast tuning ability (based on PIN diode switching technology) makes the antenna suitable for most of the conventional modulation types.
Low profile antenna with superior gain performance - optimized for the 30-90 MHz and 225-450 MHz bands Fast tuning to a new frequency band allows the antenna to be used in different kind of applications Supports also very wide transmission bandwidths
