Some Information about Antenna Tower Mast You Should Know

In the US, 240 million 9-1-1 calls are made every year. What would become of the world without the brave first responders who respond to these calls?

A portable tower or telescopic mast is one of their most important tools in the field. It helps provide a clear line of communication and a real-time picture of what's happening in an emergency. The best masts don't require specialized training and are easy enough for one person to deploy in minutes.

Read on to learn how first responders can use a portable tower to make their jobs easier and safer.

Portable Antenna Tower

Antennas pick up radio waves, a form of light that travels at 186,000 miles per second. They appear as both electric and magnetic fields and create charged particles that move in a current.

The radio waves oscillate between positive and negative values, and the time it takes them to go from one complete set of values to the other is called a cycle. The number of cycles they complete per second is their frequency in hertz.

This number determines what kind of wave you're dealing with. The different types include:

• Medium frequency or MF waves with frequencies of 300 kHz-30MHz

• Shortwave or high-frequency waves of 3-30MHz

• VHF or very high-frequency waves of frequencies from 30-300MHz

• UHF or ultra-high frequency waves of frequencies from 300MHz-1GHz

• Microwaves with frequencies above 1GHZ

There are 2 types of antennas. Receivers transmit signals into telephone, radio, or TV signals. Transmitters turn the signals they receive into radio waves.

An antenna tower is a structure full of radio or RF antennas. It's used to transmit and receive voice and data signals for P25, DMR, LTE, wireless broadband & more. It can also have other devices such as cameras attached to it so they can be shot up into the sky to get a better field of view.

Types of Antenna Towers

A telescopic antenna tower works like a telescope by bringing far-away objects or sounds into clearer focus. This larger category can also be broken down into other types; lattice, mast, pole, and portable towers.

Lattice towers are vertical with a triangular or extended box shape. A criss-cross structure of horizontal ladders makes them one of the tallest types.

Mast towers are often referred to just as masts or towers. They're vertical with a square or circular structure. They increase the height of communication equipment to provide a clear line of sight between transmission sites. They also tend to be extremely tall structures.

Pole towers are made from metal or concrete and elevate components up to 100 feet. They're flexible and strong enough not to need supporting materials. They typically only reach up to medium height.

A portable tower is the smallest type. They're easy enough for one person to put up in minutes to use with cameras, two-way radio antennas, outdoor Wi-Fi, LTE signal boosters, and even wireless broadband networks. They may not always reach as high as the other types but still provide many of the same benefits in a rapidly deployable footprint under 100 lbs.
