Spaun Satellite Distribution

When it comes to larger projects, we look for the industry’s best. For intercom systems, most agree it’s Aiphone. For PA systems, you have Toa. For SMATV, we recommend Spaun.

Spaun specialise in high-end commercial and satellite TV systems. They are German made, 98% in-house production and R&D, 5 year warranty on most products, and arguably the fastest system to install (so less labour cost). For the big commercial jobs, you’ll find Spaun product approval numbers on the Foxtel IPL and on Radio Parts’ product descriptions.

So, How Many Boxes?

Here’s an overview of possible solutions for satellite jobs involving, say, Foxtel Satellite IQ boxes:

Run Siamese RG6Q (05052055) from a dual LNB (01002028) to the pay TV box

2 runs of Siamese RG6Q from a quad LNB (01002034) to the boxes

Spaun SMS287F Multiswitch (00761490)
4x runs of Siamese RG6Q from multiswitch; each run to a pay TV box

Spaun
SMS2212F Multiswitch (00761500)
6x runs of Siamese RG6Q from multiswitch; each run to a pay TV box
This system can be cascaded — allowing up to multiples of 6 boxes to be added each cascade.

Signal to the Comms Room

Here we have a building that contains residencies with Free to Air (FTA) only and a hotel that contains both Satellite Pay TV and FTA. The hotel’s SMATV system is constructed using a Spaun 5-Wire system.

From the Roof

You’ll have normally a UHF antenna (say a UPA4) and a VHF antenna (V310 is common). If you’re working with Foxtel satellite, you’ll have the dish (a 90cm commercial satellite dish), LNB (01002050) and mount (00906005)—all Foxtel approved.

The FTA will be combined using a diplexer or triplexer (00763347) and fed into a Spaun distribution amp (00760598).

Calculating losses: We start with 85dB-90dB from the satellite dish. Using 6dB or 10dB attenuators (CAT10FA), it can be dropped to 75dB, where the signal is fed into a Spaun Launch Amplifier (00761522). If there is a significant amount of loss over this cable run, you might need to use slope equalisers (LE862F).

From the Comms Room up the Backbone: Losses

In this scenario, the signal is fed up a series of taps. On the top floor we have a splitter. The loss between the tap and the multiswitch on each floor is around 10-13dB, while the loss between one tap to the next tap on the floor above is around 1dB. The losses on a splitter (VTS525) is different. For this splitter, we might see a 5dB loss in all directions. It’s recommended to keep signal between 58dB to 76dB.

In-Room Connection

From the multiswitch, 2 runs of RG6 (or a single siamese run) will go to each TV point, where a diplexer will separate the FTA and satellite signal to a triple wallplate.
