What Users Say
Broadcasting Station KGFJ, Los Angeles, Cal.
"Previous to about six months ago,
we had been using porcelain and composition insulators in
our antenna system. During our recent overhaul we replaced
these insulators with 8-in. PYREX Insulators. We were
agreeably surprised to find that this change had decreased our
antenna radiation a full ampere, proving to us the efficiency
of this type of insulation.
"We have, since then, replaced a
composition lead-in insulator of a well known make with a
PYREX Insulator and judging from the results obtained
from our previous experience, we are satisfied that this
change also adds to the efficiency of this station.
"We would recommend stations who
do not use PYREX Insulation to try it and watch
results." -- H. D. Hancock, Mgr.
Radio Station KTT, Alaska Pacific
Salmon Corporation, Drier Bay, Alaska.
"This station is using a 250-watt
combination telephone and telegraph transmitter with wave
length range of 50-200 meters and 600 to 2000 meters.
"We are using ten 7-in. PYREX Antenna
Insulators also two large PYREX Lead-in Bowls in the radiating
system. Have used PYREX Insulation for several years and
have never experienced trouble with them either electrically
or mechanically. If there were a better insulator, would
certainly use them.
"The year 1926 saw he first
vacuum-tube equipment in the Alaska salmon canneries and
since the passage of the new radio law, practically all the
spark sets have been replaced with tube transmitters. I
believe you will find all new installations using PYREX
Insulators." -- J. D. Cole, Operator.
Tropical Radio Telegraph
Company, Boston, Mass.
"I have your letter relative to
our WBF Station and the use of PYREX Insulators. WBF is
one of our chain of commercial radio telegraph stations
in the United States and Central America. Our high-powered
terminal and marine stations are located at Miami, Fla.,
and New Orleans, La. We also maintain marine stations at
Mobile and Fort Morgan, Ala.
"We have used your PYREX Entering
Insulators and PYREX Stand-Off Insulators for various
purposes at practically all of our stations, and have found
them quite satisfactory wherever they have been supplied." --
William E. Beakes, Mgr.
