Satellite TV Meters are used by all installers to correctly align satellite dishes, with a Professional Satellite Meter like the Horizon USB Plus or the SatHero SH400HD DVB-S2 you can easily align any satellite dish on almost any satellite. With a satellite meter you can align satellite dishes and the meter will give you the signal strength and a measurement of the Signal Quality and will also tell you what satellite you locked on to, so for UK TV you need your Satellite Dish to be pointed at Astra 2, for German TV you need your Satellite dish pointed at Astra 1, Italian TV is broadcast from Hotbird 13east and this satellite will need a TM80S satellite dish if you want trouble free viewing in all of the UK's many winter storms. For Installers starting out we Recommend the SatDish SHHD DVB-S2 as it's an Easy to use Quality Satellite Meter, once you are established and feel the need of a Robust British Meter then we highly recommend the SatMeter that never needs to be Updated with has a built in Colour Screen which can help with those all important far away satellites which demand the very biggest satellite dishes.
