Well, what is the system that SCTV intend to use to provide their digital TV system. At first, it seemed as if a digital deflector system would be basically DTT - indeed, we at ICDG reported that (erronously as it turned out) at the time.
In fact the system developed by MDS International (MDSI) - MMDS Hypercable - is, in fact, a variant on the traditional "QAM" Multipoint Microwave Distribution System currently in use here by Chorus and NTL. (Something, that, for obvious reasons to do with marketing and politics, SCTV deny - they call it "terrestrial satellite" instead - but that's a contradiction in terms). MMDS Hypercable uses a different set of wavebands to QAM MMDS. It uses the frequency wavebands from 1.7-60 GHz, in the FM band. It allows up to 130 analogue or 2000 digital channels, although SCTV are for various reasons planning to use rather less than this - fifty digital channels. According to MDSI, a single transmitter can cover a radius of 200 km - easily covering SCTV's coverage area in Counties Cork, Kerry, and Waterford. MDSI also claim that the signal can be reflected by "a mirror, or a piece of metal, or a tree", you don't need to have a line-of-sight to the transmitter - unlike traditional MMDS. Also the head-end equipment is apparently rather cheap - equipment possibly costing thousands rather rather than millions of pounds. For the viewer, the equipment will cost £85 and include an LNB (Low Noise Block) fitted to your rooftop aerial and a Digital Set Top Box. Some people in exceptional circumstances will however need a 35cm digital minidish, simular to analogue MMDS aerials.
