Structure, Function, and Applications of Mast Cable Assemblies

When transmitting data or signals from remote locations or across vast distances, mast cable assemblies are often utilized for their ability to send high fidelity packets of data. This technology is one of the most popular methods for broadcasting and receiving radio and communications signals from faraway distances. No matter if you are establishing a military outpost, oil field communications, or just a hobby radio kit, a mast assembly can help you. Here is a little information about how mast assemblies are used and built.

What is a Mast Cable Assembly?

When you are trying to get a cell phone signal in remote areas, you often instinctually walk into areas clear of trees or overhead obstacles. A mast assembly takes advantage of this same basic principle, because it puts your transmitting and receiving equipment high up in the air where it can have unimpeded access to the overhead radio, microwave or even VHF waves. Usually this is accomplished by a motorized telescoping mast. When collapsed, it can easily fit on top of a van, yet can clear the tree line when extended.

Additionally, this device is constructed using rugged materials to protect it from elements like sun, wind, and rain. This typically means that you can trust the equipment to operate outdoors and still be safe from electrical failures that result from wear and tear due to weather. Usually, the device will have a weather proof sleeve, or may even have the cables housed within the mast itself, providing maximum protection from environmental factors.

Uses for a Mast Equipped Assembly

Electricians recommend mast assemblies for a variety of different applications. Most people know the term ‘mast’ from the mast aboard a sailing ship, and in fact, this was one of the first applications for this technology that also gave it its name. Sailors would attach small antennae to the mast of theier vessel to provide them with radio communications capabilities. Today, this deviced is used not only for radio but also satellite Internet and cellular capabilities.

Although these devices were originally used on boats, they are often seen in television broadcasting applications, on the top of network vans in the field reporting on news stories. Additionally, mast assemblies are regularly used in military operations and remote outposts. Finally, it is also not uncommon to see mast assemblies in mining and oilfield operations.


As opposed to other options, mast assemblies provide a huge benefit in that they completely prevent your cables from ever tangling. While it may not seem like a big deal, tangled wires can lead to damage to your equipment. Additionally, force from compression and abrasion are common to cables used in these types of applications. The mast itself acts as a way to keep cables organized and intact, even through repeated uses of the telescoping mast.
