5GHz Audio Video wireless link
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.
What our complete system includes:
1x Receiver mounted in a NEMA 6 rated enclosure
1x Transmitter mounted in a NEMA 6 rated enclosure
2x 28dB gain Antennas with mounting brackets. (tripods or mast pipe not included)
2x 5m coaxial cable with N connectors
2x Power supplies to convert 110-240V AC to 15 volts DC
1x Installation manual
Expected range for this system is 10-20 kilometres. With dish antennas this can be extended further.
You can order extra receivers or transmitters separately, they are listed separately at the bottom of this page. You can also order omni-directional antenna for field work (reportage) since it doesn't require antennas to be aligned in the same direction.
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, it is best to use dish antennas since they ensure that the transmitter will not interfere with the receiver in this case since they are very close together.
