Model AY-250 220-290 MHz 13 dBi. Gain 
 

YAGI ANTENNA

Design Features: Antenna Experts Yagi antenna design reflects innovative modern antenna construction. The unique design of the AY-250 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 facilitates mounting on either vertical or horizontal members. The yagi antenna when packed comes with elements removed from the antenna boom for ease of packing and transportation. The small surface area of the yagi antenna minimizes wind resistance and conserves tower loading capacity.

Constructions: Radiating elements, supporting booms and adjoining metal castings of AY-250 yagi antenna have been constructed in high quality 6063T6 ultra corrossion resistant 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. This directional yagi antenna, comes factory tuned and does not require any field adjustment. This yagi antenna can be assembled at site with simple hand-tools.
