Do you need Comcast HD box to watch HD channels?

I don't have cable and this TV was able to pull HD-quality channels "right off the air." Some of them aren't always in HD, the signal deteriorating from time to time. Others are more consistent.

Yes, if you only want to use this for watching Netflix/Amazon Prime, Pamdora etc you will not need another cable box. If you want to watch live TV, you will need to either get a cable/Sat box or get a digital OTA antenna .

I have Comcast and I just plugged to cable itself into the EyeTV Hybrid and it pulls in ALL the unencrypted digital channels without needing the cable set-top box at all.

it has only VGA, DVI and HDMI inputs, so if your cable box uses hdmi as its output, then you can watch TV on it but in most cases no it cant

Eddy, Most HD TVs will pick up the digital signals (older HD "ready" models require a converter box). So, you shouldn't need a converter box to receive the digital signals, just an antenna. This box will not pick up any digital channels without using an antenna as well. However, if you do need a converter box, I would not recommend this one. I had one and it went out after a few months.

I get Comcast basic service so I did not use an antenna. So my answer will be hypothetical based on what I read and know. If you do not receive cable or your cable company encrypts all channels then you will need an antenna. A quick way to check if you cable is encrypted is to just run the cable from the wall to your tv, bypassing any cable boxes, and run setup on the tv. Any channels you can receive this way you will also receive with this product. The antenna you need will vary where you live. The farther away from a city the more likely you need a bigger antenna. See this website for addition help, http://www.fcc.gov/guides/antennas-and-digital-television This device Accepts coax connection from an antenna which is pretty standard. For the box you can connect it to your tv with coax, hdmi, Component or composite. Hope this helps.

You will see the best the LNA40550 has to offer if you upgrade your cable box to HD.It's the difference between looking thru frosted glass

It will give you the ability to watch over the air channels such as ABC, NBC, CBS, FOX and PBS in high definition. You cannot watch cable channels using an antenna.

at best you'd get the local channels by plugging in a split coaxial cable without the cable-box to decode... if they are not encrypted.alternatively you can run a coaxial cable to a standard antenna (preferably external, but some internal rabbit-ears will do) to get local stations in HD over-the-air. fyi.. if you can receive them, over-the-air channels are actually of HIGHER quality than signals "passed through" by cable companies (who compress their signals)

No. It just has a cable tv type F connector. If you connect an antenna to it and can receive local hd broadcasts, then you can see HD. Also, some cable systems have a "raw" digital HD feed that does not require a cable set top box, but will play HD thru the F connector.

You can connect the cable antenna directly to this tuner and it will receive the QAM channels that your cable company puts on the cable. Some do and some don't. Ours does. So do not need to rent a box from the cable company. Only is any good if your cable company has open QAM

If you have analog cable, you will still receive analog signals after the conversion to digital broadcasting; the cable company will do the conversion. The Tivo box will work just fine. You will not be able to view HD programs without a HD cable box and a HD monitor.

Phone and internet, yes. TV, you will still need to rent the Comcast HD box...

You need and HD source. OTA antenna if you can pick up locals, sat., or cable box with HDMI or component outputs.

Yes. It also has a digital tuner for over-the-air broadcasts and QAM cable signals, so no need for a box if you have basic cable our an antenna.

Comcast here encrypts most of their HD content, so you'll need to pay extra rent for their box. QAM tuners like the ones in some TVs won't do the trick. Comcast also compress content. Comcast sux.
