Introduction to TVRO antenna and Satellite communication antenna

Posted by Cathy Liu on July 25th, 2016

TVRO antenna,Television receive-only (TVRO) is a term used chiefly in North America to refer to the reception of satellite television from FSS-type satellites, generally on C-band analog; free-to-air and unconnected to a commercial DBS provider. TVRO was the main means of consumer satellite reception in the United States and Canada until the mid-1990s with the arrival of direct-broadcast satellite television services such as PrimeStar, USSB, Bell TV, DirecTV, Dish Network, Sky TV which transmit Ku signals. While these services are at least theoretically based on open standards (DVB-S, MPEG-2, MPEG-4), the majority of services are encrypted and require proprietary decoder hardware. TVRO systems relied on feeds being transmitted unencrypted and using open-standards, which heavily contrasts to DBS systems in the region.

Satellite communication antenna. The primary specifications of an Earth Station Antenna (ESA) are given by shape, diameter, azimuth, elevation, fixed or tracking, de-ice system. It’s important that technicians appreciate the theoretical aspects of antennas, in order to react effectively when the antenna has to be repositioned or when setting up radio/HPA output power which relies on knowing the antenna gain and feed system losses.
