You can take a peek at my profile -- for about the past four years I've been working at Winegard Company, a manufacturer of off-air TV antennas and satellite dishes for home and RV. During this time I've learned a lot about off-air reception, the tricks and trials, the pros and cons, and most of all, getting HDTV with an antenna. There is a lot of confusion out there, like where it is transmitting, why am I getting zero signal when I am so close to the transmitter, which antenna is right for me, like the SquareShooter, SharpShooter, Silver Sensor, ChannelMaster 4228, or can my current antenna get HD (WHICH IT CAN!!!)?
OK I selfishly dropped these names since these are popular antennas that people may do a Google search on, possibly leading you to this stop on the information superhighway -- I am a bit of a sneak and a wise guy, consider yourself warned!!
Since this is my welcome post I am expecting no comments at this time, next time I will open things up with comments and a bit of myth-busting. But I do invite those of you painfully browsing for a simple answer to visit a site to see your capablility of getting local HDTV. It is http://www.checkhd.com/ and all you need is your zip code to get you going. After getting going you will see what HD shows AND special multicast programs are available off-air in your area! Then click on the "Antenna Guide" link, sponsored by Winegard Company, to check your coverage. The strength is listed based on strongest to weakest on a color map (from strong to weak it is --- yellow, green, light green, red, blue, and violet). The popular HDTV antennas that have been topics of discussion on other blogs I mentioned may be able to receive DTV signals up to red, possibly blue with a preamp or signal booster with a low noise figure (NF of 4.5 dB or lower). Violet ones may need a larger antenna, and if there are only a couple stations listed (or none at all), you are probably in a very weak coverage area, possibly in a low valley surrounded by hills that can block off-air signal reception (cable and satellite may fare better for you unless you are willing to try a monster antenna on a tower).
The CheckHD antenna guide will also tell you the directions the off-air signals are coming in from. You also need to pay attention to the "Frequency Assignment" column on the far right of the results page, because that is the ACTUAL channel the DTV programming is transmitting on (for instance WLS in Chicago is ABC 7, and you can watch it in HD by tuning in 7-1 on a working DTV tuner, but the signal is ACTUALLY transmitting on channel 52). So, if all the frequency assignments are 14 and higher, then a UHF antenna is all you need. BUT, there is a catch -- when analog eventually shuts down (Congress is presently debating a December 2008 hard shutdown date), some channels in VHF (7-13 for the most part) in the US are intending to return to that analog frequency assignment for exclusive digital broadcasting. So in most areas an antenna tuned to channels 7 and higher may do the job now and in the long run.
There is a map on the antenna selector -- entering your complete address will give more accurate results as some neighborhoods in a single zip code have better coverage than others. If you are concerned about giving your address over a Web site, just try the zip code and click on the map until your reach your neighborhood -- the covergae prediction WILL UPDATE automatically, and your home address will not be visible on the Web page.
So hopefully this will get you rolling, and once you see my next post feel free to share the issues, I will also hook you up for more information on getting answers, too. I think I am going to appreciate having a Wi-Fi enabled laptop and PDA!!! To find the answers you are seeking, begin by clicking the "Archives" links on the left end of this Web page.
