The SHF2367 is one of the longest 23 cm antenna manufactured in series production and is 22 λ in length and has almost 20 dBd in gain.
The side lobe attenuation is 17 dB.
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 is useless if unwanted signals or interference is being received from the back side of the antenna. EME or SAT users 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…
