Model No: FG2227-21X4CP

FEATURES:

The FG2227-21 is a high gain, Wave Guide Fed Yagi. Computer optimized for use in the 2210-2245 MHz band. Me-

chanically optimized computer calculations are held by CNC cut rod elements. The low-loss Radome strengthens the an-

tenna as well as providing protection against inclement weather and snow build up on the element structure. The stand-

ard assembly configuration is RHCP, Changing to LHCP is easily achieved by altering the connector position. Contact M2

for complete instructions.

FG2227-21X4CP ASSEMBLY INSTRUCTIONS

STEP 1:

Install MOUNTING BASE PLATE to

CROSS BOOM. Tighten all hardware.

STEP 2:

Install the ANTENNA to the MOUNTING

BASE PLATE . Make sure to mount the AN-

TENNA at its balance point listed in graphic

to reduce stress on elevation positioner mo-

tor. Leave hardware loose to orient for circu-

lar polarity.

STEP 3:

Install ANTENNAS 3 onto MOUNTING

BASE PLATE. For proper circular polarity of

the system, ANTENNA 3 needs to be oriented

the same direction as ANTENNA 1. Use the

FEED CONNECTORS as reference for ELE-

MENT orientation. See graphic. Leave hard-

ware loose.

STEP 4:

Install the two remaining ANTENNAS (2

and 4). They need to be oriented in the same

direction as each other, but perpendicular to

the first two ANTENNAS (1 and 3) installed.

Continue leaving hardware loose.

STEP 9:

Connect PHASING CABLES to the POWER DIVIDER. Connect the PHASING CABLES such that

the ANTENNAS oriented in the same direction are on the same end of the POWER DIVIDER. PHAS-

ING CABLES for ANTENNA 1 and 3 should be directly across from each other. PHASING CABLES for

ANTENNAS 2 and 4 should be directly across from each other.
