TETRA BAND ANTENNA

Design Features: Antenna Experts Yagi antenna design reflects innovative modern antenna construction. The unique design of the yagi antenna feed which works as matching device to keep the VSWR low resulting in increased efficiency of the yagi antenna. The mounting hardware supplied with the antenna is made of type 316 marine grade stainless steel which facilitates mounting on either vertical or horizontal members. Powder coating of the complete TETRA band yagi antenna provides extra protection against corrosion in saline weather present in coastal areas. The yagi antenna comes in pre-assembled condition with permanently fixed elements in the support boom. The small surface area on the yagi antenna minimizes wind resistance and conserves tower loading capacity.

Constructions: Radiating elements, supporting booms and adjoining metal castings of AY-840 yagi antenna have been constructed in high quality 6063T6 ultra corrosion resistant architectural anodize aluminum alloys to prevent corrosion. The yagi antenna uses special feed which eliminates the use of folded dipole. The Yagi antenna is supplied with N termination fixed on the driven element. The feed point radiator is enclosed in a Nylon housing designed to protect against severe environmental conditions and minimize pattern distortion. This directional yagi antenna comes factory tuned and does not require any field adjustment.
