TV Antenna VS Satellite Dish: What's The Difference

Cost Difference

A satellite dish is typically easier to install and the cost of the materials are approximately the same. A standard satellite dish installation, which would be a mini-dish installed in a south-facing wall with a cable up to 15m meters would cost less than an aerial installation that would need to be installed on the roof and may take twice as long. But the important factor here is that with the combined cost of a satellite receiver which will be required to decode the satellite signals this would usually make the satellite TV service more expensive to install.

Large “Non-Standard Properties”

If you live in a large property then installing a TV aerial may just be out of the question owing to gaining access as high as you need to be. In situations like this, a satellite dish would usually be the most economical option. This is because satellite dishes receive their TV signals from satellites up in space they can actually work on the ground providing that the satellite dish has a clear view of the satellites and there are no obstructions blocking the signal. Because TV aerials receive their transmissions from land-based transmitters more often than not they need to be installed high up on the building to clear nearby obstructions and to get a good signal. In which case installing a satellite dish would be far cheaper than hiring a cherry picker to install a TV aerial.

Multiple TV’s
If you intend to have TVs in more rooms than just your lounge, not uncommon to have TVs in kitchens, bedrooms, conservatories, and even bathrooms these days. This could affect the choice of whether you choose a TV aerial or satellite dish. A TV aerial has a distinct advantage over satellite dishes when running to multiple TVs as the signal can be split to feed extra TVs. So if you had 4 TV points around your home you could bring all the cables back to a central point, fit a splitter and your aerial signal cable and that will feed all of your TV points. You may need to add an amplifier to the system to overcome the cable losses associated with splitting the signals to extra TV points.
Coverage – Reception Levels
The area you’re in could be the deciding factor on whether you should install a satellite dish or TV aerial at your property. Averaging the two of these scenarios out satellite does in fact have a wider coverage area than TV services through a TV aerial. This is because the service is not as affected by the geographic landscape. A land-based broadcast from a TV transmitter, although usually installed in high positions can be blocked by the landscape, tall buildings, and trees. This results in poor signal areas and no signal areas. Satellite TV on the other hand because the satellites are beamed down from the sky at an angle are naturally much less affected by this.
Poor Weather – Heavy Rain/ Snow & Electrical Storms
Adverse weather conditions can affect your TV picture. As satellite dishes receive their signals from satellites in space. The signal has to pass through a wide variety of weather conditions. The weather most likely to cause the TV picture to fail is heavy rain, light rain shouldn’t be a problem. If you’re having problems in light rain, it’s likely your satellite dish is quite aligned correctly or the coaxial cables are not weatherproofed properly. TV Aerials although not completely immune to poor weather are much less likely to fail as they have much less rain etc to pass through before they reach the TV transmitter. TV Aerials also use a far lower frequency than satellite dishes which are also far less susceptible to adverse weather conditions.
