Connector Protection
It is recommended that each feeder-line connector be properly protected against
corrosion. This is accomplished by any sealing material such as heat-shrink,
cold-shrink, or a suitable sealing tape.
For taps, each F-port for drop connection is shipped with a protective plastic cap.
For taps, each F-port for drop connection is shipped with a protective plastic cap.
Remove these plastic caps after the tap is installed. All drop connections should be
protected against corrosion. This is accomplished by the use of appropriate sealing
material such as heat-shrink or connector boots. It is also recommended that silicon
grease be lightly applied to the threading of the drop connection.
Connection Beam
Our family of taps also consists of the Surge-Gap Stretch Tap. These taps include a
connection beam AC/RF bypass switch that enables uninterrupted downstream
signal flow when the tap faceplate is removed. These units are identifiable by a blue
dot on the back of the housing. The end-of-line Surge-Gap Taps should be installed
with power-blocking, 75 Ω terminators on the downstream output port.
