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.

Coaxial connectors are used to connect coaxial cables to devices, to external power supplies or to other cables, while still maintaining the outer interference shielding. Some common coaxial connectors are: N-type, 7/16 DIN, BNC, TNC, SMA and QMA.

The N-type connector is a threaded, weatherproof, medium-size RF connector for durable applications and can operate up to 11 GHz.

The 7/16 DIN connector is a threaded, waterproof connector with a 7 mm center conductor and a 16 mm internal diameter of the outer conductor. It can operate up to 7.5 GHz and is suitable for operation in extreme weather conditions.

The BNC connector features a twist and snap bayonet connection design that requires a quarter-turn to form a connection. It is generally used for low frequency applications up to 2 GHz.

The TNC connector is a miniature threaded version of the BNC connector with a more rugged and waterproof design.

The SMA connector is a 50 Ohm connector with a wide variety of forms.

The QMA connector is similar to a SMA connector, however its snap-lock design allows for faster and easier connections and disconnection, with rotational capabilities for better installation flexibility.

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.

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.
