FEATURES:

The 23CM22EZB is a revised version of our popular and proven 23CM22EZ. The 23CM22EZB now supports rear and
center* mounting (*with some restrictions). While rear mounting is the preferred mounting method, center mounting pro-
vides mounting flexibility for more compact installations or rovers. The element sets are laser cut, holding spacing and
element lengths to .003" tolerance. Each antenna performs as perfectly as the next and the gain tops any other antenna
of comparable boom length. With excellent directivity and a very clean pattern, it is perfect for high gain stacked arrays.
Vertical stacks provide the gain of a much larger antenna with a smaller turning radius and without reducing the azimuth
beam width. Applications are long haul tropo, EME, ATV, Repeater, Rover and satellite operations. The 'EZ' is handy for
'hill-topping' and portable uses because of its modest size, weight, simple construction and rear mounting.
Structurally, the 23CM22EZB elements are fabricated in just TWO sets, eliminating ALL measurement and assembly
errors. The Broad band folded dipole driven element design is unique, with a balun and matching inside the folded dipole
itself. External connections are limited to a single O-ring sealed "N" feed.
and aluminum brazed housing. When other designs are deteriorating from environmental factors, the '23CM22EZB will
still be as good as new and performing to 'spec'!

  • Page 4 23CM22EZB TUNNING DETAIL COMMENT: The dipole is fabricated with the dipole straight up so the mounting screw can be inserted and tightened and for best match. If you have good VSWR measurement equipment, using this tipping method to optimize the match at the frequency of choice. A good match (well under 1.5:1) will occur from 1250 to 1300 mHz.
  • Page 5 23CM22EZB ASSEMBLY MANUAL Access cap COMPLEX PHASING TECHNIQUES EXPLAINED When phasing antenna arrays, there are some standard rules, such as: “all antennas need to mount identically not mirror image” and “phasing lines need to be ALL EVEN or ALL ODD halfwave multiples”. These are good basic rules.
