Stainless Steel Auto Match

This is the replacement match for the HD FMJ Antenna. 

NOTE – Never Remove or Loosen any of the Bolts, Washers, Nuts, or Caps on the AutoMatch.

Construction:

• Stainless-Steel

Use:

• Uses an inductance matching network to match the capacitance of the new Alpha antenna elements.

Hardware Specifications:

• SO239 connector
• 3/8 24 bolt

Max Power (Watts):

• 250 PEP SSB
• 125 CW
• 25 Digital

Additional Information: For assembly we use a stainless-steel housing, which has non-magnetic characteristics to eliminate eddy currents. A transformer is then wrapped in a dielectric made from flame retardant tar paper, which is then placed inside the housing. This is what gives the AutoMatch both the capacitive and inductive balance once the elements are installed.

We recommend the UHF Elbow “L” Adapter with PL259 & SO239 for installation on pre-2022 mounts.

For additional use, please refer to the FMJ Antenna manuals that can be found on this page: User Manuals – Alpha Antenna
