HTA-20 (190-1122) Operation Faxback Doc. # 14957 To turn on the transceiver, set POWER to ON. Set POWER on the amplifier to on. The POWER indicator lights. When you transceiver transmits, its low-power signal is sent to the HTA-20. The amplifier boosts the transmitted power and sends the signal to the antenna for transmission. The TX indicator lights during transmission. When you transceiver receives, the received signals are routed through the amplifier's helical narrow band pass filter to reduce undesirable out-of- band signal interference, amplified by the low-noise GaAs FET pre- amplifier, then sent back to the transceiver.
