- Project: Satellite Master Antenna Television System (SMATV)
- Client: Orion Hotel
The client required a Television Distribution system capable of providing a number of international channels to over 180 outlet positions with the use of a standard television set in each room.
To accommodate this requirement, CAI Vision installed a high gain directional TV/Radio aerial array, 4 satellite dishes ranging from 85cm to 1.8m in diameter and a 21 channel professional 19” rack mounted head end to process the required channels as listed below:
- 5 x National terrestrial TV stations
- 3 x French satellite stations
- 3 x German satellite stations
- 2 x Italian satellite stations
- 2 x English satellite stations
- 1 x Russian satellite station
- 1 x Spanish satellite station
- 3 x Radio stations
- 1 x VCR playback station
A variety of problems needed to be overcome such as:
- How to fix a dish of 1.8m in diameter securely to withstand winds of upto 100mph
- How to prevent interference from the microwave signals beamed across the city from the BT tower to the main BT satellite uplink station at Woolwich
- How to minimise the multipath images from surrounding tower blocks and co channel interference from other TV transmitters
With careful consideration to the choice of equipment of the highest standards and consultation with the building surveyor all the listed problems were resolved resulting in a successful installation and a satisfied client.
