Collinear antenna A4-165 grows out careful computer calculation and practical adaptations of a light design to such incompatible parameters, as gain and the broadband coordination.
Despite of the low price, the antenna is characterized by rather wide working strip in 12 MHz and the increased gain nearby 5 dBi. Owing to application qualitative fiberglass radome, the antenna has the rigid not folding design, capable to provide communication links in any climatic conditions.
