No Side Lobes
Carrier Class Symmetrical Horns have no side lobes - they only focus energy into one main signal beam. Such radiation characteristic saves the most important resource in wireless - the spectrum.
The unique radiation properties secure, that radio will collect and propagate significantly less noise in comparison with mainstream sector antennas. Majority of noise problem is directly connected with antenna side lobes, especially when operating in free bands. Side radiation lobes allow radios propagate to- and receive the signal (noise, interference) from unwanted directions with surprisingly high gain.
Carrier Class Symmetrical Horns are basically "deaf" off their main beam, so they deliver significantly better performance in crowded, noisy environment.
Carrier Class Symmetrical Horn Antennas are very compact, with only 20-25% footprint of traditional (patch array) sector antennas. This compact size saves tower rental fees, and makes it possible to install Carrier Class Symmetrical Horns in places where regular sectors would not be allowed due to their shape and size.
