Commercial Antennas Have Become Less Intrusive

The aluminum antenna forest that once sprouted from nearly every suburban rooftop has nearly disappeared, a casualty of the digital revolution. While this is a welcome development, modern communications and media still often require over-the-air transmission and reception. Strong signals and reliable coverage are always important, but so is the impact these units can have on everyday living.

At its most basic level, an antenna consists of poles, wires, dishes and other metal devices designed to both receive or send electromagnetic signals. Commercial antennas are integral to generating money, and are used by television, radio, cell phone and other communications enterprises. Amateur home radio transmitters, satellite dishes, and other related devices are not considered commercial.

Before a business can place a new installation, however, a number of local issues must be seriously considered. Although consumers purchasing new electronic communications expect that they will have strong, reliable connections, most simply do not want to actually see the necessary installations and towers that make the entire experience possible. Because of this understandable attitude, cities have created new regulations regarding antenna visibility, size, and location.

A high-tech antenna array sporting gleaming metal spikes might appeal to some, but generally not to those people living in its shadow. This understandable attitude has driven technicians to new levels of creativity when designing and placing new installations, with the goal of making them less obtrusive. Many of these solutions are based on the concept that new equipment should be almost invisible to casual observers.

The most basic way of accomplishing that is called co-location, a common solution to placement issues. Co-location puts new equipment on an existing tower, eliminating the need for additional construction. This process often involves working together with other companies using that tower, must not interfere with current operations, and must conform to existing standards of aesthetic appearance.

For many new services, however, co-location is not feasible. In those cases, there are often stringent regulations for new construction. Although cities vary, most have rules that attempt to accommodate the needs of both service provider and customer. In many areas, new towers may not be constructed in a side or front yard, and cannot disrupt current traffic flow or eliminate current parking capacity.

In addition, the color scheme has to blend properly with existing designs. A new antenna must not block the view from adjacent homes. Some regions stipulate that all connective wiring be run beneath ground, and covered by vegetation or landscaping when above ground. Ordinances regarding height must be followed. Although these requirements may seem restrictive, the positive outcome is a new generation of towers that most people happily never notice.

Where ugly metal once sprouted, people now see greenery. In New York state, towers are disguised as deciduous trees, while in Los Angeles they may resemble palms. Some newer antennas are specially created to match and blend into other unique natural environments, and many are doing that job very well. The result, although initially somewhat costlier, is proving very popular with service providers and consumers alike.
