M2 Antenna Systems 2MCP22 Assembly Manual - 2McP22 Assembly Manual
14. To add the support, install a 2" U-bolt into the 1-1/2” x 4” TURNBUCKLE PLATE and attach the
turnbuckles. Temporarily install the turnbuckle U-bolt studs into the top set of U-bolt holes in the boom
to mast plate and loosely secure with a couple of 5/16” nuts. This "locks" the alignment of the
turnbuckle plate to the boom to mast position. Install the two U-clips into the boom and secure with
retainers. Rotate boom so clips are vertical.
15. Now attach one end of the BLACK DACRON SUPPORT CORD to the front U-clip. Two turns of
cord and a square knot is adequate. Heat-seal the left over end and tape back to the main line. Route
the cord back to the rear clip and knot the same. Even-up excess cord at the turnbuckle plate and cut.
The turnbuckles should be extended until just a thread or two shows inside the body of the turnbuckle.
Attach cord ends to the turnbuckles as on the U- clips. When completed, the two lines should be tight,
the turnbuckles laying flat out just over the boom. After the antenna is installed to a mast, the
turnbuckle plate is attached and slid up about one foot until the boom is straight. Use the turnbuckles
to balance and fine tune the support. After final adjustments, safety-wire the turnbuckles to maintain
settings.
16. The 2M22CP is a circular polarized antenna and creates a field in all planes or polarities.
PERFORMANCE DETERIORATES SIGNIFICANTLY if it is mounted on a metal (conductive) mast /
crossboom or if the feedline exits the boom anywhere but at the rear. A 2” mast or crossboom of any
NON-CONDUCTIVE material can be used. Fiberglass is the prime choice for its strength and weather
resistance (1/4” wall x 2” O.D. Fiberglass tube is available from M
2
). Mount the 2M14CP so that
element tips are at least 12” from any conductive material (mast, tower, feedline, etc.).
THIS COMPLETES THE ANTENNA ASSEMBLY.
