Compatible Antennas: ANT 005, ANT 021, ANT 024, ANT 025, ANT 028, ANT 029, ANT 034. Refer to Williams AV’s Antenna Selection Install Guide for FCC-compliant antennas for this product.
Transmission Range: Up to 1000 ft (304 m) with ANT 005 coaxial antenna mounted on rear chassis F-connector
RF Outputs: (1x) #10-32 stud connector in center of unit (pcb mounted), (1x) F-connector on rear chassis
RF Transmit (RF) Power Indicator: 1 OLED On Air Indicator with 4 states indicating power level Off, Low, Medium, and Full Power.
RF Time Out (sleep mode): 30 min. duration, 4 hr. duration, or Always On; selected via web page. When audio drops below -18dB, the selected duration begins, and when it expires the unit stops transmitting and goes into a low-power (“sleep”) mode. Any button press or resumption of audio above -18dB “awakens” the unit and it begins transmitting again. |
