Stacking The M2 23CM22EZA Antennas
Here is some
information on stacking the M2 23CM22EZA beam antennas. The frequency range for these antennas is 1250 - 1300 MHz.
antenna has 22 elements and has a gain of 18.2 dBi. A power divider is
to connect the two antennas to the single coax feed from the radio.
Stacking these antanneas together will increase the gain by 3 dB for a
total gain of about 21 dBi.
driven elements can be adjusted to keep both antennas in phase as shown
below. This allows the antennas to be mounted so the coax feeds to the
center for a clean install. I use LMR 400 coax for the phasing lines and LMR 600 for the coax from the radio to the power divider.

Note: The M2 23CM22EZA antennas have equal capture area of 23 in high and 23 in. wide not 22" & 23" as shown.
