"PYREX" is a trade-mark and indicates
manufacture by Corning Glass Works, Corning, N. Y.
A new practical
for amateur use
HERE is a new insulator designed specifically for
hams. Two four-inch bowls and a solid brass rod make it
easy to handle and install. The high volume and surface
resistance and low power loss of PYREX electrical glass
result in clearer signals and better distance,
particularly under adverse conditions.
Inexpensive, sturdy -- the new PYREX insulator comes to
you ready for work. It is equipped with jam nuts,
gaskets, and washers. The brass rod, solid for easy
drilling, is threaded except for 3" in the center.
In two sizes, No. 67104 with 15" rod -- $2.20. No. 67105
with 20" rod -- $2.30. A folder describing this new
insulator in greater detail will be sent to you on
request. Dept F68 Corning Glass Works, Corning N. Y.
