    Antenna Y4 UHF was designed specifically to operate as a part of communication systems in regions with tough climatic conditions: at far North, mountainous regions, and maritime climatic zone. All-welded construction makes it invulnerable to icing and strong wind. Polymeric coating protects it from hostile environment. This antenna will be optimal for subscriber radio stations, operating with frequency separation 10-12 MHz, due to wide operating band. There are not so many antennas able to provide such bandwidth!
