Phased vertical stacks of two
or more antennas were fairly common in the television realm - especially once color
broadcasts became more dominant in the 1950s. Up to 3 dB per additional antenna
is possible, but due to various non-ideal physical parameters (summed phase angle
across the band,
imperfect antenna geometry, etc.), realized gain is typically in the 2.5 to 2.8 dB
range. Higher signal to noise ratios were needed to guarantee good color separation
with the National Television System Committee (NTSC) and stereo channel audio separation
with the advent of Multichannel Television Sound (MTS). As
you might expect, companies appeared claiming to have invented physics-defying antennas
that "outperform all present antennas." This particular "Super 60" model from
All Channel Antenna Corporation further claims to outperform antennas that use a
mechanical rotator (see my
Alliance U-100 Tenna-Rotor) by virtue of its 9−position electronic phase switching
device that remotely configures the cross-shaped elements in a manner that provides
selective directivity gain. It is not hard to legally make a claim of being "up
to" 10x more powerful than conventional antennas since that wording allows even being
no more powerful, provided it can be shown that in certain configurations is actually
is 10x more powerful, such as when compared to a fixed direction antenna of poor
design and/or poor installation. Lawyers love crafting statements like that.

Money Back Guaranteed to Receive All Channels 2-83 from All Directions and Positively
Outperform All Other Antennas With or Without a Rotomotor 1
Up to 10 Times More Powerful than All Present Conventional Antennas!
New, revolutionary antenna, while being up to 10 times more powerful than conventional
antennas, is still able to receive all television and FM stations from all directions
without a rotor motor of any kind. The electronic orientation switch used with a
new type transmission line developed specifically for this extra powerful antenna
now makes it possible to clearly receive stations heretofore considered out of range.
It is now possible to put up just one antenna, use just one transmission line, pay
for just one installation and receive the finest possible reception from the stations
in and coming to your area regardless of their direction.
