The repeater consists of a receiver and a transmitter built inside an weatherproof enclosure. The receiver receives the video signal in a preset frequency (say Channel 4), and the transmitter sends the video signal out in another preset frequency (say Channel 1). The repeater may be used: (a) as an intermediate booster to extend the transmission distance; or (b) to avoid obstacles in the transmission path by changing the direction of the source signal. The repeater is designed for use with our 1.2GHz transmitters/receivers here, or other compatible transmitters/receivers. See how it works here.

Use video transmitter module with stable output power.
Use high reliability/linearity/AIGaAs/GaAs FET amplifier module.
Use high reliability and sensitivity Comtech tuner module
Adopt phase locked loop circuit to eliminate frequency drift.

2) It is recommended to use antennas of at least 9dBi gain or above (option item) for the repeater.
3) Maintain a minimum distance of 2 meters (approx. 6.5') between the front and back antennas in order to avoid self interference. This can be acheived by using antenna extension cables.
4) If it is necessary to use antenna extension cable, the cable should be kept as short as possible because, the signal attenuates directly proportional to the length of the cable, i.e. the longer the cable, the weaker the signal from the antenna.
2) One 12V universal regulated AC/DC power adapter.
