Digital TV Antenna

indoor digital tv antennaDo you really need a “digital tv antenna”?
Digital TV Antenna is used to receive digital TV signals and is no different from a conventional off-air TV antenna. This is just an ordinary TV antenna that constitutes the front-end of digital TV transmisison system. TV antennas may seem like relics from the last century, but a growing number of viewers are finding them to be indispensable in getting the best picture from their HDTVs.
The switch to digital TV broadcasting has eliminated the most annoying picture distortions that made analog off-air reception so hit-or-miss. With digital TV signals, you’ll either see a crisp, ghost-free picture or no picture at all. At the present time, Cable TV is the primary source of television programming for the majority of U.S. TV viewers; additionally, multiple-millions of viewers are DBS TV subscribers.

Choosing a digital antenna

A TV Antenna that can receive traditional analog tv signals, is NOT different than an antenna that receives Digital-HDTV Signals. A TV-Antenna does not discriminate between Analog TV and Digital / HDTV Signals.

So, don’t be fooled by manufacturers and retailers which are taking advantage of the current, heightened consumer interest in all things related to Digital-HDTV. There is no thing such as digital HDTV antenna.
A digital tv antenna is the same as an analog antenna!

So choose any tv antenna you like! Like analog signals, digital TV signals can be broadcast over two different frequency ranges: VHF and UHF. The VHF channel range is 2-13 — low-band VHF is channels 2-6; high-band VHF is channels 7-13. The UHF channel range is 14-69.

Indoor vs. outdoor tv antennas

panel digital antennaIndoor antennas are small, designed to be placed on or near your TV but are affected by the walls of a house and even by movement of people in the room, household interference include fluorescent lights, computers and cordless phones.

outdoor digital tv antennaOutdoor antennas are larger and intended for roof. In general, the larger an antenna’s surface area is, the stronger the signal it will provide. Nearly all outdoor antennas perform better than even the best indoor antennas.

Installing a digital tv antenna

For digital antenna cabling always use 75-ohm coax cable. Coax cable is superior to twin-lead in every way and should be used if possible or for the best performance and reliability, use RG-6 cable.
Large outdoor antennas can be installed on a roof or a free-standing pole and for the best results, your antenna should have the clearest possible view of the transmitter tower.

  • locate and avoid power lines and other wires in the work area
  • do not climb onto a roof when there is no one else around
  • if possible, avoid chimney-mounting an antenna as smoke and gases from the chimney can impair the antenna’s performance and shorten its life

When you’re aiming the antenna it’s best to have a helper who can check picture quality and relay the information to you. Most HDTVs and HDTV tuners include an onscreen signal strength meter but be sure to check the picture on all channels you want to receive before securing the antenna in place.

    DTV just plain sucks,,,PERIOD!! I had an old magnavox I bought used at a pawn shop for $25, it lasted 8 years before I either had to fix it and shortly buy a coverter for the change over or buy a HDTV. I bought the HDTV. Then the big day came and now instead of the 3 broascaster’s and the butload of hispanics stations I use too get, I now get 1-ONE station, ABC or if I climb the roof I can get either abc, nbc, or cbs by turning the antena too recieve it. And whats worse, it only cost me $900 for something that now I hate to even turn on. OLD saying was” if it aint broke leave it the **** alone and they should have

    My Philco D-A Converter Box TB100HH9 keeps crashing, every few minutes. It may load and/or play channels, to just crash at any point. I say “crash” as then you have to turn it off and on again.

    Is it junk? I thought maybe because I was using rabbit ears as antenna, but I’m in Houston where there should be 15+ channels down the street. Analog was GREAT here, now we’re screwed.

    twin-lead or open wire is great for putting in your rubbish bin. I replace the old cable almost 6 days a week. It was good for vhf and was great in it’s day but there is a number of reasons why it is not used anymore. If it was better then RG6 then Foxtel would be using it!

    I’m in a fringe signal area with all channels on UHF and my Digital TV is Perfect 🙂

  • charles

    hey about mobile video?..after changing to digital in my car….i think i get less signal from digital..i think i got a better longer lasting pic from analog when driving ..than with digital..any sugesstions?..thanx

    You would think that coax is better, hence the surprise mentioned from Dave.

    From the antenna engineering handbook. With 100 ft of wire a twin lead will loose only 3.3 db’s compared to coax at 7.1 db’s.

    @ radiofanatic – you may need to rethink your strategy.

  • radiofanatic

    Yes, I know that RG6 coaxial cable is better than twin lead wire antenna cable.

  • Dave

    twin-lead or open wire antenna cable is very low loss when compared to Coax. Coax cable does have the advantage of it is self shielding. However with the advent of digital transmission antenna ghosting should be a thing of the past. Twin-lead cable requires special techniques for correct installation which if not followed can cause difficulties.
    I would submit that you should check for yourself the loss per 100 m. of both RG-6 and the lowly twin-lead. I think you will be surprised.
