A few months ago I posted a
write-up on the vintage
Alliance Model U-100 Tenna-Rotor that I installed in the garage attic with a
Channel Master CM5020 VHF / UHF / FM antenna atop it. There are not many television
antenna manufacturers around anymore; their numbers have been decreasing continually
due first to the advent of cable-delivered TV and now with Internet-delivered TV. The
movement is helping to give over-the-air television broadcasting a rebirth due to the
outrageous cost of subscription programming. Anyone contemplating installing a
television antenna today has the same concerns as those back in 1959 when this
Channel Master advertisement appeared in Electronics World magazine - gain,
directivity, bandwidth, ruggedness, how high to mount it, how to mount it (tower or
pole), whether to use an antenna rotator, and transmission cable type. One new issue
not normally present then is whether your community association (if one exists) allows
or controls size and mounting height of your outdoor antenna.
Channel Master Ad
Channel Master is telling the T-W story to almost
every family in the United States with the Most Spectacular Antenna Promotion of all
The Best of Antennas Delivers this Best of Promotions!
To help you sell more antenna replacements, Channel Master commercials will be broadcast
from coast to coast by 4 of America's most popular TV shows over the entire NBC and ABC
networks - 210 TV stations.
In addition to this full network coverage, 2 powerful national magazine campaigns
will put the T-W story into 17 million homes... many of them right in your community.
These ads are aimed at telling consumers that their antenna installations are becoming
old, worn out, obsolete, and that for the best possible TV reception they should replace
their antennas with the T-W. This campaign has been designed to create new business for
you by making the TV family T-W conscious.
Only Channel Master Gives the Dealer this Kind
Now meet the real star of the show...
Three years ago. Channel Master developed the Traveling Wave antenna. This breakthrough
in antenna design was so revolutionary... so far ahead of its time... that modern science
has not yet been able to produce a comparable antenna.
Here's why other antennas simply cannot equal the powerful performance of the Traveling
The T-W antenna, featuring the Traveling Wave principle, looks and operates differently
from other antennas. All but one of its elements are driven. No conventional dipoles
are used - only "hairpin" or "fat" dipoles, and a revolutionary new Controlled Impedance
Dipole. The 2-stage phasing harness... the critical lengths and angles of the elements...
the folded reflector... all combine to deliver these unique Traveling Wave advantages:
• Ideal phase relationships on all channels
• Optimum impedance on all channels
• Equal flow of current in all dipoles on all channels
• Fullest use of transmitted energy on all channels
As a result, the T-W brings your set miles closer to the TV transmitter, providing
the highest gains and highest front-to-back ratios ever achieved in a broad-band antenna.
The T-W is the stand-up-and-take-it antenna!
The T-W is as rugged as it looks. When you install the T-W, you know this hefty performer
is up to stay. It is, without a doubt, the strongest antenna ever built. Here's why:
"Twin Truss" Construction
All elements and crossarm are made with "twin truss" design. The truss is a basic
construction form used in bridges, airplane wings, and wherever high strength and light
weight are required. This "twin truss" design makes each T-W element more than 5 times
stronger than an ordinary dipole in its ability to withstand the heaviest wind and ice
Ruggedized Mast Bracket
Heavy-duty U-bolt grips the antenna to the mast. Twist-proof construction. 4 rivets
secure the bracket to the mast.
Seamless 1/2" dia. sleeves, seamless 1/2" dia. U-bend... 20% heavier wall thickness
than regular antenna construction.
"Line-Lok" Absorbs all transmission line tension. Can't tear at terminals.
Extra-thick 1/4" virgin polyethylene insulation protects impedance and electrical
efficiency against salt air, rain, and ice.
Massive, Heavy Duty Insulator Moldings
The T-W has consumer recognition and acceptance!
Millions of consumers, including those in your own area, recognize and ask for the
Channel Master brand name. Continuous full-scale advertising campaigns, local advertising,
newspaper mats, window displays, streamers, and other advertising aids have made the
American consumer T-W conscious. The Channel Master T-W out-sells, out-performs, out-lasts
every other all-channel antenna. That's why this premium quality product is still the
star of rooftop America... and a most profitable experience on the part of the dealer
and the consumer alike.
