Product Description

Product Introduction

Factory directly 1/2" Feeder Cable Telecommunications LDF4-50A Electric Common rf Coaxial 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.

What is the difference between the 1/2 feeder 75ohm 50 ohm RF Coaxial Cable and 7 8 Feeder Cable ?

In the field of RF transmission, a feeder cable is used as a transmission feed line for radio frequency signals that connect radio transmitters and receivers with their antennas.  Specifically, a feeder cable is a type of RF coaxial cable that is used to transfer radio frequency energy from one point to another. A feeder cable also provides protection for the signal.

And the 1/2 super flexible coaxial cable, which is named half inch coaxial cable, refers to a specific size of coaxial cable that is made of the following parts:

* 16mm PE Shield (or PE jacket)
* Corrugated copper tube
* 12mm foam dielectric
* Copper conductor (hollow or solid)

In the broadcasting equipment industry, 7 8 Feeder Cable has many aliases, such as:

* 7 8 coaxial cable
* 7 8 coax
* 7/8'' feeder pipe
* 7 8 feeder
* 7/8 feed tube
* 7 8 coax feeder
* etc.

7/8" Cable Super Flexible is a type of RF coaxial cable which is used to transfer RF signals from one point to another which allows for precise bending and handling when needed in tight spaces. 

Typically, 7/8" Cable Super Flexible is used as as Main feeder for mobile communication base stations, In-building distribution system and antenna feed lines of various wireless communication system, jumper cables to connect to an antenna of transmission equipment. 

It incorporates high foaming polyethylene insulation technology to minimize signal loss and have excellent electric features such as low damping and reflection coefficient.
