Antenna System

Designed to meet demands

for :compact sizetough constructionstrictly defined radiation patternaestethic appearance

Minimized visual impact

with :Cross-polarized and dual bandantennaDuplexers

New MHAprovide higher gain than the oldoneimproves RX sensitivity and filtersout interferencereduces call drop-outs

Ultimately increasesrevenues for operators
