WIMO SHF 2367 23cm-Yagi 67-Element 19,9 dBD

As far as we know this is one of 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.

The antennas have an very high f/b ratio because of the use of 8 reflectors. This is in particular important for high-gain yagis: even the highest gain gets useless if unwanted signals or interferences are being received from the back side of the antenna. EME or SAT freaks enjoy our antennas due to the low backward noise scatter (from the surface of the earth). All nuts, bolts and washers are manufactured of stainless steel. For those antennas with support strut also the mast clamp itself is made of stainless steel (where else do you find this?).
The antennas are delivered pre-mounted with all elements already in place. They can be assembled in about 10 minutes; you don't have to read the manual (which is provided of course...) and it does not take an engineering approach to install the antenna and get into the air...
