SATELLITE UPDATE SPECIAL On Friday, a516digital reported of the growing concern among British expats that they might soon lose all the main UK TV channels following the sudden change in the footprint of the transponder that is currently testing BBC One HD in preparation for the launch of national variations for Scotland and Wales. It is widely assumed that this transponder has moved to the new Astra 2F satellite and its tighter UK spot beam.
Based on internet user reports, this is the latest a516digital.com map of the Astra 2F spotbeam footprint, compiled using reception reports of the BBC One HD "test" transponder (11023 H). Please see the following footnotes with regards the map:
- Realistically, the spotbeam is unlikely to be as smoothly formed as depicted, and there will be local "hot" and "not" -spots around the fringe, including side lobes. Around the edges signal strength varies dramatically within short distances. This map from 3pmfooty.com showing a former satellite's footprint shows how spotbeams aren't nice and smooth in real life: http://www.3pmfooty.com/images/Iberiafoot.jpg (a516digital.com is not responsible for the availability or content of external links)
- The 60cm ring and inwards shows the core of the spotbeam, where normal domestic satellite dishes built for the UK and Republic of Ireland market can be used to receive the service.
- Some types of dish, such as the "Multytenne" dish, widely sold and used in some countries tend to outperform traditional dishes and are reported to be able to receive Astra 2F in areas where larger dishes are typically required.
- The map has been set conservatively to reflect areas where reception is available 24/7 and where a dish of a certain size will provide reception during all but the worst of weather.
- The map aims to reflect areas where services can be received by the majority of normal satellite receiving equipment. For example, Barcelona is on the edge, with some viewers able and some viewers unable to receive services with a dish size around the 1 metre level.
- The dish size markers refer to the lines on the map, and nothing else. For example, the presence of the 1m marker over Germany does not mean the whole country needs a dish that size.
- Viewers with suitably sensitive specialist and semi-professional satellite equipment can, in effect, stretch the zones outwards and receive services with a smaller dish than shown or receive services beyond the outer ring.
- Local satellite installers will be able to provide advice for viewers around the fringe area and be able to measure local signal strength (see first point, above)
- Astra 2F will host all UK public service broadcasters. Most Sky subscription channels are not affected.
- This is based on assessing data from reception reports on the internet. There has been no official word as yet from satellite operator SES or the BBC.
