Coax Cable (Without Ends)

FAQs

Are short coaxial cables better for high frequency signal transmission and reduction in signal interference and signal leakage in cable television systems?

Yes, short coaxial cables are better for high frequency signal transmission and reduction in signal interference and signal leakage in cable television systems.

What are the electrical characteristics of triaxial cable?

Triaxial cable has electrical characteristics that include low capacitance, high shielding effectiveness, and reduced signal interference, making it ideal for applications requiring precise and high-quality signal transmission.

Waterproofing Coax Connections

Improper waterproofing on coax cable connections accounts for the majority of communication failures. In order to ensure a proper seal is made, it is important to use products that are intended for this type of application. Waterproofing kits include 3M vinyl electrical tape, referred to as Tem Flex, and butyl mastic adhesive, which is what actually provides the waterproofing and protection for the connection itself.

The 3 Steps to Waterproof Coax Connections:

Step 1: Take the 3M electrical tape and begin to apply the electrical tape at least one inch outside of the factory heat shrink cable. Wrap the electrical tape around the connection overlapping each time until you reach the other side of the connection. 

Step 2: Take the butyl mastic adhesive and begin to apply it one inch past the electrical tape. When applying the butyl mastic adhesive, make sure to pull it very tightly around the connection as you continue overlapping each time around until you reach the other side of the connection. Butyl basic adhesive is a clay like substance that must be worked until it becomes a solid unit.

Step 3: The last step in making this connection is to once again, use the vinyl electrical tape. The purpose of this step is to simply provide protection for the butyl mastic adhesive itself. Begin to apply the electrical tape one inch outside the butyl mastic. Wrap the electrical tape around the connection overlapping each time until you reach one inch past the butyl mastic on the other side. You now have a completely waterproof and UV resistant connection that will last for years to come.
