Commercial Antennas Have Improved Their Appearance

By Essie Osborn


The thick forest of television antennas that used to grow from the rooftops of suburbia has disappeared, a welcome result of evolving technology. Although the digital age has arrived, modern communications still rely heavily upon over-the-air, antenna-based reception and transmission, requiring the construction of many additional antenna structures. While excellent coverage is essential, those new units should not create a negative impact on daily life.

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.

Business operators are increasingly faced with a variety of issues that must be addressed before any new equipment can be placed. Consumers buying electronic communications devices naturally want them to work dependably and with reliable reception, but do not want to actually see the necessary towers or broadcast installations that make good electronic service possible. Most cities have been forced to create new regulations on location, size and visibility.

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.

One of the most successful methods of reaching that goal is termed co-location. This process places the necessary new hardware on the face of an already existing base, doing away with the need for new construction. Because other companies are already using that tower, the design must fit into their operations, must not impact them negatively, and cannot be aesthetically inappropriate.

When co-location is not an option, and a new tower must be built, local regulations are the key to success. Although the laws vary, many cities have approved strict new rules regarding the appearance of these towers. For example, many residential neighborhoods forbid placing a new antenna in a side or front yard simply because it looks bad. New installations cannot interfere with vehicle flow, or eliminate 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.

For many residents, the results look like nature. In California they may look like palm trees, while those in New York sport deciduous branches. Other towers have been disguised to blend into unique natural desert backgrounds. Although designing antennas to fit the natural world may initially cost a little more, it proven to be a popular practice that benefits both business and consumer.
