The SGC Smartlock is ideal for mobile use, or any installation where antenna conditions may change. It provides two external controls for the SG-230/237/239 Smartuner. The locking function prevents retuning despite changing antenna loads. The reset function forces the coupler into a retune cycle the next time a signal is transmitted. Tune and lock status is indicated by one green and one red blinking LED. Supplied with 9 foot connecting cable.
For use with SG-230/237/239 couplers manufactured after July 1, 1993 only.
DC Coaxial Line Isolator
The DC coaxial line isolator allows antenna couplers, antenna switches, pre-amplifiers and other DC powered equipment at the antenna feed line to be powered through the RF transmission line. It eliminates the need for a separate cable to power these devices. It will allow up to 25VDC at 1.5 Amps to be supplied over 150 feet. Two isolators are required per installation and included in each set. The unit measures 3L x 2W x 1.6H inches.
RF In/Out Port Isolation:
Better than 80 dB, 1.5 - 30MHz
Better than 70 dB, 30 - 50MHz
Better than 40 dB thru 250MHz
RG-213 coaxial cable recommended for distances over 100 feet.
