I went back and reread the PDF specifications sheet for the 'triple-boom' ANI-700 antenna and it says it is designed to receive channels 14-69. However, the same page also says 470-862 mHz, which covers channels 14-83. ANI-AV
Then I found the specifications sheet for the similar 'triple-boom' Televes DAT-75, and it's listed frequency coverage is 471.25-847.25 mHz, Channels 14-76. Televes DAT 75 TV Aerial (Televes 159702)
The 'triple-boom' design of these two antennas is quite unique and that makes me wonder about them. If this is a superior design, why haven't I ever seen even one remotely similar antenna used anywhere else for any other service?
There are 6 TV Towers within 5 miles of my home and they have dozens of secondary-service antennas all over them, primarily dishes and "true" Yagis. The old microwave telephone towers and new cell phone towers have secondary antenna services on them, but nothing like the two antennas mentioned above.
Seattle is a seaport and none of the Merchant Marine, Fishing Fleet, Coast Guard or Naval ships use anything similar. I have seen dozens of Ham radio towers and never seen a similar antenna used.
I conclude both of these antennas may work in Europe but they are a poor choice for TV reception in the Americas, considering all TV channels from 52-83 have been eliminated. I also suspect they are fancy-looking gimmics.
