Video Audio Repeater
This repeater can solve the problem of "how do I get my signal through or around that obstruction?"

A repeater is a device that will receive a signal then retransmit the same signal. Normally located on an elevated structure or mountain. If located on a tall building, it can repeat the video/audio signal from one side of town to the other.

It also means the normal range of a receiver and transmitter combination are now doubled.

Early repeaters were constructed in separate enclosures with two power supplies and exposed video/audio cables.

This design places all electronics inside a single weatherproof enclosure. The only cable entering the enclosure is a power cable.
This picture show a repeater using 17db gain dishes. One dish is used for receive, the other for transmit. Different sizes or combinations of dish antennas can be used to satisfy your requirements. The small light-weight design makes it suitable for portable applications.

A repeater can also be mounted in remote locations and power from either battery or solar power. The repeater requires 12 volts DC at slightly less than 1 amp.

Setup and installation is very easy. No internal adjustments are required. Simply connect the antennas to the appropriate connector and aim. Applying 12 volt DC power completes the installation.
