Digital camera Review: A Great Antenna for DTV and Over the Air HDTV
Summary: 5 Stars
I spent more time fretting over which antenna to buy than I should have. The fact is that digital TV (DTV) and HDTV are simply a UHF broadcast. ANY UHF antenna should provide some signal. The reason for purchasing a high gain antenna (such as the DB4) is that with digital, a good signal means a perfect picture. A poor signal means no picture. There is no fuzzy middle ground.
Here is a summary of the tips I gathered while researching antennas. The more closely you follow these steps, the better your results will be.
1) Go to www.antennaweb.org and click on "Choose and antenna" to determine the distance and direction of the channels you want to get.
2) If possible, mount the antenna on the roof. Attic mounting will result in 40 - 50% signal loss.
3) Orient the antenna as accurately as possible. If you have one, use a compass and the heading you got from antennaweb.org. UHF is directional, so the more accurate the direction, the better the signal.
4) Use RG-6 (Satellite) coax cable and keep the run as short as practical. The same length of RG-59 (CATV) cable will result in much more signal loss.
That said, here's what was working against me. 1) I am a fairly distant 40 miles from all of the transmitters. 2) I didn't feel like messing around on the roof, so I mounted the antenna in the attic. If interested, my antenna mount consisted of a scrap piece of conduit and a spare conduit strap. Total cost should be less than $4. On the plus side, I did aim the antenna as best as possible and I had a fairly short length (32 feet) of RG-6.
My unscientific analysis was to look at the signal strength meter function of the digital TV converter box. It is simply a scale from 0 to 100. To my surprise, the signal strength was in the 90's for all of the channels. That is better than expected.
Basically, this is a very good antenna. Just remember that the better the installation job, the better your reception will be.
Summary of Antennas Direct DB4 Multi-Directional HDTV Antenna
The DB4 from Antennas Direct has become one of the most popular models of HDTV digital antennas because it is simply one of the bests mid-range HDTV antennas on the market. With an approximate 13.7dB of gain, it is one of the strongest multidirectional antennas available and performs consistently across the entire UHF spectrum. It even works well in areas where HD transmitters are sending in signals from multiple directions. The bow tie design of the DB4 uses triangular elements instead of rods to greatly increase the bandwidth allowing it to cover the entire UHF band.Antennas
