"This company owns and operates
its own radio system comprising radio telephone equipment
aboard nine tugs operating in and around the vicinity of
Los Angeles harbor, also the radio equipment aboard the
Steamers Catalina, Avalon and Carbillo, carrying passengers
between Wilmington and Avalon, Santa Catalina Island.
"The insulators used are the regular
6-in. PYREX Type, with the exception of steamers Catalina
and Avalon, where 12-in. type is in use. PYREX Stand-Off
Insulators are used also on our tug-boat and steamer radio
"PYREX Insulators have always
given 100 per cent service although as you know, short-wave
radio-telephony aboard small craft is somewhat difficult."

"We are using PYREX Antenna insulators
on our transmitting antenna and have found them in every way
"When our antenna was originally
constructed the top mast came down in a heavy gale, due to
temporary guying, and bent it almost beyond recognition.
The antenna came down with it, the total fall being 110

"We have been using PYREX Insulators
for about sixteen months and find them entirely satisfactory.
Our antenna system is insulated with two of your 30-in.

insulators, and in addition we use small PYREX insulators for
receiving antennas, two entering insulators and two stand-off
"Replacement of conventional
porcelain insulators with PYREX insulation increased our
antenna current in damp weather. PYREX insulators are
certainly the most satisfactory for their uses." -- Dramin

"We are using approximately thirty
8-in. PYREX Stand-Off Insulators, and approximately twenty
3-in. PYREX Stand-Off Insulators in our transmitting equipment.
They are for the most part used in the oscillating circuits,
subjected to a voltage of 10,000 volts. We are thoroughly
satisfied with the way they function both electrically and
mechanically." -- Leonard T. Carlson, Engineer.
