Despite a natural instinct to
be suspicious about new products claiming to to be a panacea to all problems
pertaining a particular subject, it seems magazines of all eras have been filled
with advertisements pitching such products. Not all are total scams, but the
usefulness is often more narrow in scope than implied or explicitly stated in
the ad. An example is high gain vacuum tube replacements for televisions which
promised to improve picture quality in noisy or low signal strength
environments. They could potentially result in a better picture, but often all
that happened was both signal and noise levels increased to result in a brighter
image, which then required turning down the brightness control; i.e., no overall
real improvement. Antennas are another example of "miracle" cures for reception
woes. The truth is that unless you lived in a high quality signal area, nothing
short of a high gain directional antenna on the roof would do a really good job
of pulling in a great picture (and sound). Set-top rabbit ears or wires running
up the wall and across the ceiling were shot-in-the-dark efforts. Excluding
weather and traffic related multipath signal variations, unless all the
broadcast stations you wanted to receive were located within a few degrees of
each other relative to your position, adjusting of the antenna configuration was
required when changing channels. This Magic Carpet Antenna no doubt solved
reception problems for some situations, but it doubtful that such a
configuration resulted in universal improvement. Magic Carpet Antenna Ad
The Lid's Off!
Jerrold announces the all printed circuit antenna ... the first new concept in
TV-FM reception in 10 years!
Indoor Antenna-Outdoor Design! Jerrold's new Magic Carpet* is a flat, flexible
all printed circuit antenna based on a broad-banded dipole design. Installed indoors
in attic, crawl space, closet or any upper level location in the home, it offers
performance comparable to a conical type outdoor antenna (mounted in the same location)**
at a fraction of the cost.
A report on the Magic Carpet in the May issue of Electronics World states "Gain
characteristics across all frequencies are very close to those of standard outdoor
conicals." No more need for unsightly rooftop or indoor antenna (up to 30 miles
from the TV transmitter). The Magic Carpet opens up a whole new antenna market for
the TV and FM Serviceman.
