While the 432-13WL produces over 23 dBd gain in a four Yagi array, its also an excellent stand alone antenna. And, for the serious amateur it would make a sensational 16 Yagi 432 array. The driven element is a modified and adjustable folded dipole. Its heart is a unique machined aluminum Driven Element Module. All three connectors on the module are threaded in and feature 'O' ring seals. Internal connections are encapsulated in a space age silicone gel with nearly 4 times the dielectric strength of air. Each parasitic element is a solid 3/16" rod, mounted through the boom on a UV stabilized, black polyethelene button insulator and locked in place with stainless steel shaft retainers.The 432-13WL has been designed for outstanding performance and long term electrical and mechanical integrity.
