Coax Cable (Without Ends)

Coaxial cable is a form of signal transmission cable that is used to transmit electrical signals between components, devices or systems. It is used to send radio frequency (RF) signals in the form of electromagnetic waves, unlike standard electrical cable which consists of wires through which an electrical current is passed. The design of coaxial cable consists of an inner conductor, usually copper, which is then insulated with a dielectric maternal, then wrapped in some form of shielding such as woven copper, and then wrapped in a plastic jacket. Coaxial cable can transmit high-frequency signals with low degradation and signal loss.
Some applications require coaxial cables to be exposed to extreme temperatures, abrasions, chemicals and extensive flexing. The variables have a direct impact on the materials used for cable insulation and jacketing as well as the construction of the cable. LMR type coaxial cable can meet such demands.
LMR cables are high performance broadband, flexible, low loss 50 Ohm coaxial communication cables. The polyethylene jacket, closed cell foam poly dielectric and bonded tape conductor results in better weather resistance. LMR-195 is ideal as a drop-in replacement for RG-58 and RG-142. It is commonly used in antenna jumpers, cabinet interconnects and RFID. LMR-240 can be used for in-building cabinet intra-connects, SCADA antenna systems and RFID. LMR-400 is the industry standard for short RF feeder requirements. It is used as a drop-in replacement for RG-8/9913 air-dielectric type cable, public safety antenna installations, antenna feeder runs and WiFi. LMR-600 is ideal for high power applications, long antenna runs, private land mobile radio networks and WiFi.

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.
