Features

QuestTel's Satellite L-Band optical fiber Transmitter/Receiver set offers high pefromance and cost effective alternative to conventional coaxial systems. The L-Band Transmitter and Receiver pair is used for transporting L-Band RF over fiber from the antenna to the satellite receiver. Additionally transmitter provides optional 13/18V LNB power as well as Automatic Gain Control (AGC) to manage RF input level.  By transporting the L-Band RF over fiber this range can be extended from several hundred feet to over 10 miles (Optional  20, 40, 80 and 120km declared before order). Since optical signal is not affected by electromagnetic field, the quality of your signal will always stay at the high level. Also this fiber solution is more cost effective than coaxial system, as well as more reliable and flexible.
