Savanna
Savanna - Head-End set of 6 PAL VSB channels from 6 QPSK multiplexes.

Obsolete, last few left, phone for price

SAVANNA headends are economical, high performance and space-efficient all-in-one solution comprising set of 6 FTA Digital Satellite TV receivers that deliver 6 TV programmes on conventional, analogue UHF channels.
The headends consist of 6 receivers and a PSU arranged on a metal, wall-fixing baseplate. The receivers are pre-linked and ready for use. All that needs to be done is to program the units using the SPI-300 programming tool!

  • The headends have six loop-through pre-configured F input ports - one per receiver.
  • The 6 channel combined output is delivered at the output port.
  • The headend is powered as a whole when connecting it to the mains.
  • By using the supplied jumpers, the appropriate voltage/tone signals can be injected to power up the LNB.
  • The six receivers are individually programmable.
