Model No: FG170-230-5
FEATURES:
The M2 170-230-5 Helix antenna offers medium performance characteristics for specialized fixed and rapid de-
ploy operations within the 170 to 230 MHz band. It is perfect for either terrestrial or satellite applications. The antenna is
supplied with a manually adjustable Azimuth / Elevation mount and a counter weight. The antenna is shipped with the
helix assembled less ground plane. Finishes are optional. The steel adjustable mounting fixture and counterweight are
zinc plated. Optional arrays of 2 or more are available. Other frequency ranges and gains are also available 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.
