Coaxial 1/2″ Feeder Cable

1/2″ Feeder Cable is a type of RF coaxial cable which is used in many applications where it is necessary to transfer radio frequency energy from one point to another such as In-building distribution system and various wireless communication system. It incorporates high foaming polyethylene insulation technology to minimize signal loss and have excellent electric features such as low damping and reflection coefficient.

This cable carries current in both the inner and the outer conductors. These current are equal and opposite and as a result all the fields are confined within the cable and it neither radiates nor picks up signals. This means that the cable operates by propagating an electromagnetic wave inside the cable. As there are no fields outside the coax cable it is not affected by nearby objects. Accordingly it is ideal for applications where the RF cable has to be routed through or around buildings or close to many other objects
