The ATA3090M from COJOT is an autonomous tunable antenna for the 30 to 90 MHz frequency band that does not require any external control. It therefore offers a perfect solution to easily enhance existing radio systems. This low profile antenna tunes automatically to use the optimum matching circuitry at the required frequency. The ATA3090M provides superior gain performance over traditional wideband antennas.
Features
- No external control required
- Easy upgrade for current radio systems
- Low profile antenna with superior gain performance
