Wireless Video Repeater

The repeater consists of a receiver and a transmitter built inside an enclosure. The receiver receives the video signal in a preset frequency (channel 4), and the transmitter sends the video signal out in another preset frequency (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

The enclosure is not weatherproof and therefore for installation indoor or under shelter only, i.e. not directly exposed to rain, snow or sunshine. For weatherproof model, please click here.

Use compact 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.

Transmission range: Range may vary substantially depending on the actual operating environment. Longer distance can be achieved if high gain directional antennas are installed in a line of sight environment. Estimated maximum transmission distance in an unobstructed environment between two static points using 12dBi Yagi directional antennas on both sides is about 40 miles (64 km).

Notes:

1)    Assuming that the transmission path is a line of sight environment, it is recommended that Yagi directional antennas, panel antennas or other directional antennas be used on both sides of the video repeater.

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.
