Bringing Distant Stations Closer
Nearby stations thunder in because the antenna gathers in an ample supply of energy.
Distant stations lose energy on their way to your set. Conserving these faint signals through perfect insulation of your antenna is just like moving your set toward a station.
PYREX all-weather insulators improve reception by cutting down antenna leakage.
PYREX is the trademark of a special composition possessing distinctive electrical characteristics. It is not an ordinary glass.
PYREX Broadcast Insulators retail for 45 cents.
