ANT RX\TX 12V ANTENNA 50Ω FREQUENCY RANGE EQUAL TO OR GREATER OF 28-30MHz 10 METERS BAND MAXIMUM POWER SUPPOR-TED BY ANTENNA NOT LESS THAN 240W PAY ATTENTION TO THE POWER POLARITY RADIO INSTALLATION NOTE CONNECTION DIAGRAM This device must be installed in an area where there is adequate ventilation for the heat sink. The amplifier is not designed for continuous transmission and should not be operated in this manner. Failure to observe this will cause the amplifier to shut down from excessive temperature. If the amplifier is operated in high ambient temperatures transmission times should be kept short to avoid excessive heat sink temperature. Excessive heat sink temperature will cause the amplifier to shut down transmission. This is indicated when the TX LED flashes. If this occurs operation of the amplifier should be stopped and the amplifier will regain normal operation when the temperature falls to an acceptable level. This may take more than 5 minutes.
