5GHz microwave audio-video link system - Now 4 channels  


5GHz Audio Video wireless link - now either 1 or 4 video channels with stereo audio!

Why use 5.8 GHz for Video/Audio Transmission?

The advantage of 5.8 GHz Is Clear! (a clearer picture that is!). 5.8 GHz systems offer much higher immunity to the interference found on older 2.4 GHz frequency video systems. The 2.4 GHz frequency band is now heavily populated by wireless Internet WiFi and Bluetooth devices not to mention interference from microwave ovens! Our 5.8 GHz systems also have an excellent bright color picture. Better than 2.4 GHz systems out there! Antennas are much smaller and offer higher gain or amplification than the same size at 2.4 GHz or lower frequencies.
Many customers are using our systems to link their TV studios to their distant transmitters! They can also be used for radio stations, of course. In this case the free video channel can be used to remotely monitor various equipment or studio. All of our transmitters and receivers are analog and not digital. This means real-time pictures and audio without lag or delay like many digital systems do.

Perfect to transmit multiple video channels across property, saves money and space!

What is included in our 5GHz Video/Audio link system:

1x Receiver mounted in weatherproof NEMA 6 rated enclosure with integrated high gain panel antenna
1x Transmitter mounted in a weatherproof NEMA 6 rated enclosure with integrated antenna
2x Mounting brackets for receiver and antenna
2x Universal mains power supplies to convert 110-240V AC to 12 volts DC, 1A
1x Manual

What is the difference between 1-channel and 4-channel versions?
1-channel version supports 1 video channel and 2 audio (1x stereo)
4-channel version supports 4 video channels and 8 audio channels (4x stereo)

Expected range for this system without additional upgrade options is up to about 3km. With dish antennas this can be extended further, check below.

What does the 2W amplifier do?
The 2W amplifier can significantly increase the range. 2W amplifier and two grid antennas can increase the range to around 20km max. 2W amplifier comes with mains power supply.

What do the grid antennas do?
You can install a 28dB gain antenna at the receiver or at the transmitter. The best result is of course obtained if you use them at the both sides of the link. If you use grid antenna at both sites and also the 2W amplifier you can sometimes obtain even more than 20km of range.

What to do if we don't have optical visibility between the receiver and transmitter?
If you are having problems getting around an obstacle, perhaps a big building or a hill, order one extra system and set it up as a repeater. How? Simple, place one system on the top of the hill that is blocking the wireless link. Now send your signal up to the hill, it will be received there by a receiver and immediately re-transmitted to the final receiver. Your repeater system will have receivers output directly feeding the transmitter. When setting up repeaters use only high-gain directional antennas since they ensure that the transmitter will not interfere with the receiver in this case since they are very close together.

What is the best possible system setup for maximum range?
1x5GHz Video/Audio link system with power supply
2x28dB grid antenna with 5m coaxial cable
1x2W 5GHz amplifier with power supply
