Product Discription:
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.
