Heliax Cable Wire, Heliax Cable is part of Allied Wire and Cable’s extensive stock of Coaxial Cable in fact.

This selection of Coaxial Cables is designed for signal transfers in am/FM radio, UHF/VHS TV, and other communication systems in fact.

In fact, heliax is a trademarked name for Hard-Line cable. Hardline is used in broadcasting as well as many other forms of radio communication.

It is a coaxial cable constructed using round copper, silver or gold tubing or a combination of such metals as a shield in fact.

Some lower-quality hard line may use aluminum shielding, aluminum, however, is easily oxidized and unlike silver or gold oxide, aluminum oxide drastically loses effective conductivity.

Therefore all connections must be air and watertight. The center conductor may consist of solid copper or copper-plated aluminum in fact.

Since skin effect is an issue with RF, copper plating provides sufficient surface for an effective conductor.

Most varieties of hardline used for external chassis or when exposed to the elements have a PVC jacket; however, some internal applications may omit the insulation jacket.

Hardline can be very thick, typically at least a half-inch or 13 mm and up to several times that, and has low loss even at high power.

Then these large-scale hard lines are almost always used in the connection between a transmitter on the ground and the antenna or aerial on a tower.

Coaxial cables are essentially just cables made of wire which carry radio or television signals in fact.

Also, they are used for carrying television networks from a distributor to individual houses, which is why the service is known as Cable TV.

Their distinct thick, the round shape is due to a heavy layer of interior insulation which is designed, in part, to reduce the effect of magnetic fields on the signal the cable carries.

As well as reduce the amount of signal loss which occurs as signals pass through great lengths of coaxial cable.
