I received the antenna today! One week from ordering until delivery. I haven't hooked it up yet. I have read the paperwork and thought this item would be a nice pass-along. They direct me to
http://www.antennaweb.org/to find out broadcast locations and channels in my area (to help choose and orient the correct antenna type - mine covers them all by being multidirectional and signal boosted). Going to that site and plugging in my Zip Code revealed that there are 13 broadcasters transmitting 37 channels to my location! This site also contains some technical info to help choose antenna types, sources, links to network deals for the internet, etc. I guess it's the promotional ties that helps pay the site bills but still informative and a possible deal to a needy buyer.
I should add a point I overlooked because I have a relatively new TV. This stuff is about TVs that are digitally built and not the old analog TVs. I suppose if you have one of the A-to-D converter boxes, your all set too. The TV needs to be able to search /tune for viable signals so I don't think older TVs can do that, sorry.
Eddendum: That 37 channels is just for the antenna. The paperwork says the antenna is good for signal towers within about 35 miles (go a bit more because Florida is flat?) I didn't get any distance increase commitment with the amplifier paperwork. I'd hope that will increase the number of broadcasters and channels I'll get, especially at night time with an ionosphere bounce like ham radios. I'll have to remember to do a signal search routine in daylight and at night to see if there's a difference.
