Question

Can cable and/or satellite TV interfere with over the air digital TV transmissions?

Answer 1

In North America at least, the frequencies of over-the-air (OTA) channels and those of satellite downlinks are so vastly different that there is no way that the satellite signal is going to interfere with the OTA signal. For starters, note that the satellite transmitter is about 18,000 miles away from you while the OTA transmitter is probably closer than 60 miles, with vastly more power.



If you are having difficulty receiving OTA channels, the solution is always a better antenna installation, one way or another. Go to the web site below, enter your local info, and you'll get a personalized report on what OTA channels you should be able to receive and what type of antenna is recommended. (The web site is for viewers in the U.S. or Canada.)

Answer 2

I love watching television, The pet is enjoyed by me shows, the medical shows and the Judges and court docket shows

Answer 3

There are plenty of many experiences out there that don't have movies. Books can explore principles and ideas without having to be anxious in regards to a special effects budget.

Answer 4

Satellite Tv Interference

Answer 5

Well, it really depends more on how you watch TV. If you're big into "on demand" programming then cable may be better for you as DTV doesn't have really have any other than PPV movies. Other than that, I prefer DTV and have been a subscriber for 10 years. The main reason for me is DTV's exclusive rights to NFL Ticket. If you want that you have no choice but to go with DTV. On another note, a lot of people talk about losing the signa, when it rains, snows, etc. In the 10 years I have had DTV I can probably count on 2 hands the number of times I lost service completely. It has to be raining pretty darn hard for this to happen and I live in the Deep South which sees quite a bit of rain & storms in the spring & summer.

Answer 6

they will not. satellite dishes and FTAs have different frequencies. it's like radio frequency that when you switch frequencies you'll get different stations.

Answer 7

It can if there's signal leakage, but typically cable lines use fiber-optic which shouldn't interfere, and the coax that goes to your house is either RG-6 of RG-11, which should prevent any cable signals from getting out and any TV signals from getting in as long as the cable isn't damaged.



With satellite, the only issue is between satellite dish and receiver/television. But again, the coax cable is shielded to prevent any signal leakage.

Answer 8

No it can't.



You can't get OTA channels because you are using the wrong antenna or you are in the middle of nowhere.

Answer 9

DVB Digital Terrestrial broadcasts are in the UHF range of frequencies and usually unaffected by broadcasts from satellite - which are broadcast at much higher frequencies.

Only a faulty Receiver can affect reception really and peak sunspot activity/environmental factors.

One of the main reasons a digital terrestrial signal is not available in a region is that Analogue transmissions are still active there.



Because these are on the exact same frequencies,it's not viable to broadcast until the frequency is clear.

Reception problems on DVB are usually because the aerial is not aligned correctly to the transmitter,or the incorrect type of aerial (see bands).

Every model of Digital terrestrial Receiver has a different sensitivity, if you are close to a transmitter you may need an attenuator in line,if far you should get the most sensitive model.

Cable cannot interfere with anything - it's shielded within the cable it's delivered by.



Yes there's a way to test if RF is coming out of another appliance attached to a neighbours roof,however this is very very unlikely - you'll need a frequency counter,and a qualified Technician to operate it and provide a report.

*If you have a local CB or Ham radio enthusiast nearby that's far more likely to interfere.
