CKD ANTENNAS
THE ULTIMATE KNOCK DOWN ANTENNA



The CKD antennas from KTI are packed with features not available on any other Complete Knock Down antenna.

The KTI CKD antennas, with their intermediate ring design, optimize the parabolic curve of the mesh between the ribs.  The intermediate ring serves three major functions:  first and foremost, it increases the gain compared to antennas without an intermediate ring, while at the same time adding increased structural integrity to the antenna.  Of equal importance, the intermediate ring with the stainless steel retaining clips reduces the possibility of mesh blow-out in high wind areas.

KTI's high performance features are also included in the ProFORM mount.  The mount ring for the CKD antennas has an attachment point to each of the antenna ribs, plus six bolts securing the center plate to the mount.  This design locks the reflector to the mount, eliminating that wobble in the wind, common with other knockdown antennas.  KTI's polar mount features a one-piece 3/4" machined pivot axis that rotates within two oil-impregnated shoulder bushings ensuring years of trouble-free satellite tracking.
