Dammit Ernie, once again you prove that I am not to old to learn sump'n new.

Other things to consider, last year we were bidding on a large natl. account that required HD antennas. So back to testing we went.
During this process we were surprised to find that VHF still exists and "most" flat antennas do not get VHF.
Also most of the newer flat units have a range of about 30 miles (good) and 50 (max).
If the stations are at near hard angles to each other plan for a multi-element ant. and if you decide to go flat you may need multiple units plus a combiner.

We started in business 35 years ago installing rooftop VHF/UHF antenna systems. Since that time I estimate that we have installed over 20,000 antenna systems. We still install 2 or 3 systems a week.

My favorite brand in Winegard and the most popular model is the HD-7694. It is not a large antenna but performs great. The secret to installing HD antennas is to know where the signal is the strongest. We use Sadelco digital meters and walk up on the roof and measure signal levels at different spots and heights for all channels. It is important to not install the antenna where it is a dead spot for a major channel.

When we measure the signal levels we can move the antenna 10' or less and receive 3 or 4 times more signal at the different locations. Tv antenna signals are like cellular phone signals. If you are in a spot where you have no service you pull out your phone and start walking looking at the meter. Walk 10' and suddenly you have 2 or 3 bars. Walk back to the old location and your call drops.

Lately, we have been installing and upgrading OTA HD antenna systems in apartment buildings. In our area we can normally provide for close to 60 channels from Washington and Baltimore. People love the fact that they can cut the cord from their cable or satellite provider.

Yup, I am one who never subbed to cable or pizza dish, I do have internet with the cable co. I use netflix and you tube player among others off the net, OTA here gives a bit over 20 channels and the big dish gives me about 1000 channels. So in all I pay my internet and my $8 to netflix and I'm in good hands :)
