As far as we know this is the longest 23 cm antenna manufactured in series production. The antenna has 22 λ in length and almost 20 dBD in gain, it's a high tech/high performance product. All mounting parts and nuts are made of stainless steel. Due to the 8x-reflector the antenna shows a very high front to back ratio (f/b). At 19.9 dBD gain the antenna has a gain of 22 dBi (over isotropic). The side lobe attenuation is 17 dB. The entire performance of the antenna follows the physical laws and is optimized by CAE-design. The E- and H-plane 3-dB beamwidth are practically equal and facilitates therefore the stacking and combination of several identical yagis to form a high gain antenna array. The antenna covers the entire 23 cm band and does not display any de-tuning effects caused by rain or wind. The support strut is designed so that the antenna does not mechanically deform in the horizontal plane.
