M2 Antenna Systems, Inc.
Model No: 500-1000-10
FEATURES:
The M2 500-1000-10 Helix antenna model is designed to meet environmental condition specified by MIL-STD-
810 and offers performance characteristics for specialized fixed and rapid deploy operations within the 500 to 1000 MHz
band. It is perfect for either terrestrial or satellite applications. The antenna is supplied with a manually adjustable Azi-
muth / Elevation mount and a counter weight. The antenna is shipped with the helix assembled less ground plane. The
Finish is gold anodyne plating. The steel adjustable mounting fixture and counterweight are zinc plated. Optional tactical
carrying cases are available. Optional arrays of 2 or more are available. Other frequency ranges and gains are also avail-
able down to 100 MHz. Complete motorized, computer controlled AZ-EL systems are also manufactured by M2.
Where circular polarity is not required but high bandwidth is, M2 offers a line of various log periodic antennas from 5 to
1300 MHz. If it is antenna related, we probably have made it. Call us with your requirements.

TOOLS REQUIRED: #2 Phillips head screwdriver, 11/32 nut driver and 7/16” socket open end wrench.
1. Unpack the factory assembled HELICAL antenna, the CENTER REFLECTOR PLATE, and the two (2) REFLECTOR
HALVES. Attach the Reflector halves to the Center Reflector Plate using 8-32 x 3/4” screws and locknuts.
2. Add the g-plane clamp #1 to the center reflector plate near the center hole using 1/4-20 x 3/4 bolts and lock wash-
ers. Then slide the assembly up the rear end of the helix boom. Align the hole in the rear boom section of the helix
assembly with that of the g-plane clamp #1 and use a 1/4-20 x 3/4” bolt to set the position of the ground plane by
threading the bolt through the g-plane clamp #1 and into the boom. This sets the position of the ground plane. Then
add the g-plane clamp #2 and secure using 1/4-20 x 2 1/2 bolts and locknuts.
3. Slide the feed support block on to the helix, note that the hole in the support block is off set, install the block so there
is the greatest distance between the helix and the ground plane. Align the holes on the ground plain and leave loose
at this point. Then slide the ‘N’-connector block assembly on the helix and rotate the connector down through the
large hole in the plate. Secure the block to the plate with four (4) 8-32 x 1-1/2” screws and locknuts. Add the 1/4-20
bolt through the feed block support and ground plane and secure. Now install the 1/4-20 x 1/4” set screw in the
round end of the feed block assembly and tighten, using the supplied 1/8” Allen wrench. Note set screw markings
from original test assembly. Helix should protrude no more than 1/8” past the feed post. This completes the assem-
bly.

4. Assemble the Elevation Bracket hardware as shown on the assembly picture. For the time being
set the elevation angle to 0 deg. (mast bracket perpendicular to the antenna). Attach the 1.5” saddle
adapter plate to the elevation bracket. Next, using four 1/4-20 x 2 3/4” bolts and locknuts, attach the
four saddles loosely to the saddle adapter plate. Now slide the entire assembly onto the back of the
boom, position right up against the mounting plate collar, and set the feed connector to the desired
rotational orientation. Tighten the four saddle bolts.
5. With an associate, slide the antenna onto the top of a 2” support pole. Point the antenna to the
proper azimuth and elevation angles, and tighten all of 1/4-20 hardware on the mast clamp bracket.
Add the optional counter balance weight to the end of the heical, slide the weight to a position that
will provide balance to the antenna system, add 1/4-20 set screws to hold the position of counter bal-
ance. Drill through the counter balance locking pin hole and secure with a 1/4-20 x 4 1/2 bolt and lock
nut.
This completes the assembly.
