The M2 120-150-9 Helix antenna offers high performance characteristics for specialized fixed operations within the 120-150 MHz band. It is perfect for either terrestrial or satellite applications. The antenna is supplied with several sections with the ground plane not installed. Finishes are optional. 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.
