Ham Radio Antenna Tower -

A Ham radio antenna tower is usually a metal tower that hams use to support their antennas. In order to understand what a Antenna Tower is, you must understand what it is used for, and to understand that one should know what do 'hams' (as the amateur radio operators call themselves) actually do.

< Mecca's previous Tower >

First of all, to become a 'ham' you need to have an Amateur Radio Operator. Now there are over 3 million amateur radio operators with a license.

The purpose of an antenna tower is to sustain the antenna that 'hams' need to communicate with. With towers 'hams' use larger antennas that are required by the longer wavelengths of lower frequencies, but in general all kinds of antennas are used. The average 146-MHz (2-meter) antenna is a 19 inch long quarter wave whip, but hams are known to use a variety of other antennas and even cheaper solutions (such as aluminum ladders, flagpoles with buried coaxial cable, etc). In any case it's important to know what kind of antenna you are going to use for it will significantly influence the tower you will use.

There are many factors that one must take account when talking about an antenna tower, such as the type and size of the antenna, the weather in the region the tower is going to be installed, the wind-load rating of the area (for United States towers rated to sustain a wind-load of at least 87 mph should be fine) and so on. The terrain on which the tower will be installed is also very important, as are the installation processes and the constant maintenance of the tower. Other additional features are also important, for example MECCA equip their towers with systems that put up and bring down the antenna automatically so you don't need to climb the tower yourself and go out to press the button because MECCA's tower has a indoor controller. Antenna towers can be installed directly on the ground or on top of houses or other buildings.

Mecca has tried to recreate the previous Mecca's Ham tower which is available on the top of building, and of which length is 16m.

We are pleased to introduce WorldWind that is a new brand of our crank-up tower to Hams in the world. There are five models, WorldWind 16HAN, 16, 21, 26, and 32. The number of name means the maximum length of it. HAN of 'WorldWind16HAN' represents the family name of our CEO who is a creator and engineer of WorldWind.
