<\/p>\nOne of the most common mistakes new satellite viewers make is buying a dish that is too small for their location. A dish that works perfectly in Spain may struggle in the UK or northern Europe, even when pointing at the same satellite. Choosing the right size the first time saves money, frustration and a second climb onto the roof.<\/p>\n

The key factor is the satellite’s footprint<\/strong> \u2014 the area on Earth where the broadcast signal is strong enough to receive. Satellites like Astra 19.2\u00b0E and Hot Bird 13\u00b0E are designed to cover Europe, but signal strength drops off at the edges of the footprint. The further you are from the centre, the larger dish you need.<\/p>\n While exact figures vary by satellite and transponder, these general guidelines apply:<\/p>\n If you want HD or 4K channels<\/strong>, err on the larger side. HD channels typically use higher symbol rates and more complex modulation (8PSK), which requires a stronger carrier-to-noise ratio than standard-definition broadcasts. A dish that gives a fuzzy but watchable SD picture may pixelate badly on HD channels.<\/p>\n A larger dish also gives you weather margin<\/strong>. During heavy rain or snow, signals attenuate. A dish with 3 dB of extra headroom will stay locked through a storm, while a borderline dish will cut out. This is especially important for critical channels like news or sports.<\/p>\n Bigger dishes are heavier and wind-load more. On a wall mount, an 80 cm dish in a exposed coastal location can pull significant load in gales. Check that your bracket and wall fixings are rated for the dish size you choose. If in doubt, use a heavy-duty wall bracket or a ground pole mount.<\/p>\n Finally, remember that dish size and LNB quality work together. A high-quality low-noise LNB on a smaller dish can sometimes match a larger dish with a cheap LNB \u2014 so don’t blow the entire budget on the dish alone.<\/p>\n","protected":false},"excerpt":{"rendered":" Why Dish Size Matters One of the most common mistakes new satellite viewers make is buying a dish that is too small for their location.
