In this oustanding antenna we have redesigned the array of radiating elements in such way that antenna is highly immune for signals come from distant stations, outside of the mainbeam direction. This is because all noises and interfering signals are not collected by highly suppresed sidelobes of this unique antenna.

TetraAnt 2 19 20 RSLL delivers a very strong and clean (high S/N) microwave power even in the most interfering environement. Is is especially sufficent in the dense urban area with a lot of microwave networks. Because the pattern of antenna is the same for transmit and receive mode it also do not interfers with other networks.
