Slovensko Air Band Transceivers
PolMar PL-760 VHF Air Band Transceiver (PL-760)
PolMar PL-760 VHF Air Band Transceiver
PolMar PL-760 VHF Air Band Transceiver is designed for experimental aircraft with limited panel space and requiring low power consumption, the PL-760 fits a standard 5.7 cm (2-1/4") instrument hole.
With it’s built-in voice activated intercom with manual squelch control, the PL-760 has proven superior performance in the noisy environment that kit aircraft are known for. The PL-760 has a 5 Watt transmitter, a 11-33 V power supply, and com frequency range of 118.00 to 136.975 MHz.
