The Atlantic Ice Parol of the U. S.
Coast Guard Service sends its warnings of icebergs to the
transatlantic liners from PYREX insulated antennae. The
same service also depends on PYREX insulators for all coastal
patrol operations.
The U. S. Navy, Lighthouse Service and
the Air Mail System, all vitally interested in dependable
transmission, specify PYREX Insulators.
Over fifty of the broadcasting stations,
including several "super-powers," have found it advantageous
to originally equip, or to refit, their antennae with them.
In 1924, the first constant schedule
amateur transmission from the United States to Europe was
carried over PYREX equipped antennae.
The new :Directional Beam: system
also uses PYREX Radio Insulators. The stations in Long Island
and California, now under construction for commercial
transcontinental service, will employ many thousand PYREX
insulators for the insulation of the individual wires which,
arranged in parabola form, make up the antennae.
The general adoption of PYREX radio
insulators whenever results are of extreme importance, is an
indication of the reliance which experienced radio engineers
place upon them.
As a means of obtaining satisfactory
service, quality in transmission, and improvement in reception,
PYREX insulators have proven their worth.
