Omni-Directional vs. Directional Antennas: What are the Differences?

One of the disadvantages of technology is that it sometimes makes certain choices more difficult even while hardware like our Cintenna portable DMX wireless system is itself relatively easy to use. For example, once you have installed one of our wireless, Omni-directional DMX units into the DMX input of your lighting device, you may still have to decide which kind of antenna is best for you – directional or Omni-directional. Here are some differences between the two kinds of antenna.

Omni-Directional vs. Directional Antennas

Omni-directional antennas, as the name suggests, radiate and receive energy equally well in all directions. Think of this kind of antenna as working like a lamp. The light from a lamp radiates outward in all directions. However, this 360 degree transmission is not always either required or desirable for light engineers. Sometimes a technician may desire that the available energy radiated by an antenna be pinpointed in a particular direction. In this case, a directional antenna would be more suitable. Directional antennas allow RF energy to be focused in a particular direction. This would be desirable, for example, if a technician needed the transmission to be focused in areas such as hallways, long corridors, isle structures with spaces in between, etc.

The Pros and Cons of Each

No technology solution is ever perfect nor is technology always one size fits all. Both kinds of antennas have their advantages and disadvantages and it is up to the light technician to figure which is more appropriate for his or her needs. Since directional antenna need to face particular areas in which coverage is needed it can sometimes lead to mounting challenges. Moreover, directional antennas have less angular coverage by their very nature than Omni-directional antennas. The advantage they have over Omni-directional antennas is that they are usually more powerful. On the other hand, there are Omni-directional antennas. The advantages to them are that they are generally easier to install and they do not face the mounting challenges that directional antennas do plus they cover a broader area. One disadvantage is that they generally have less range than directional antennas do. In either case, it takes a careful assessment of exactly what is needed for your production to determine which is the most suitable. We can help you fulfill those needs with our Strand dimmers and our Strand dimmer repair service as well as our DMX devices. We can also help you lower production cost with our equipment rentals.  cintenna
