The Alpha FMJ
(Full Metal Jacket) system is a basic FEA (Field Expedient Antenna) that will handle 500W PEP SSB, and which is pre-tuned and requires no moving clips on coils or readjusting of whips for tuning. You may also use an external antenna tuner if your antenna is installed over a poor ground or not placed in a clear area.
When fully deployed with the NVIS element, the antenna system is directional and can be is configured to launch your signal at your target in the opposite direction the NVIS element is run. For an omnidirectional signal pattern, you may remove the NVIS element.
Installation Note: Never Remove or Loosen any of the Bolts, Washers, Nuts, or Caps on the Alpha Match.
Years of perfecting the manufacturing process has enabled Alpha Antenna to offer the worlds most refined & resilient antenna, which is now in use by NASA and military forces around the globe. (Ref.
For targeted rapid deployment of ALE/Digital/CW/SSB/AM modes. The Alpha FMJ
(Full Metal Jacket) system enhances high band DX with the Vertical MilStick element while low band Near Vertical Incident Skywave is simultaneously enhanced with the NVIS element, per the antenna model at the bottom of this page.

No changing of switches, jumpers or coils are required for touch free operations.
Directional; Unique also to only to the Alpha Multiband Antenna line of systems is a directional antenna system for international DX communications that also enhances NVIS (Near Vertical Incident Skywave) for stateside communications.
The Alpha Match: Before assembly, the inner wall of the stainless steel housing is lined with a dielectric, then the transformer is placed inside the housing. This is what gives the Alpha Match both the capacitive and inductive balance once the elements are installed. The main difference between legacy designs, which are black and made of either a plastic Delrin or PVC, is that those older designs do not have capacitive characteristics. This is what enables the Alpha Match to balance the entire antenna system once the elements are installed. It is important to note that the Alpha Match housing is made of 316 stainless steel, which has non-magnetic characteristics.
The MilStick Whip; The composite of the .433 inch diameter MilStick whip is a high strength, high quality, aerospace 7075-T9 alloy 13 feet long. The construction of each element has a scratch-resistant hard-anodized surface. This surface is fully removed from each insert and also removed 2.5 inches inside each element. The inserts are then electrically bonded, where full contact RF continuity and connectivity is used to ensure maximum efficiencies are achieved. At the base of the whip an embedded 8740 Steel (chrome moly) cadmium plated stud supports the MilStick on the Alpha Match.
The Wiring Used; Sheathed 13 AWG memory free wiring is used, which has a tensile break strength of 500 pounds that is rated for temperatures from -40°C to +75°C. VS. Wiring that is so light duty that it can be wrapped around a kite string holder.
The Padded Field Bag; Made from 600D nylon with embroidered logo and with high quality zippers. This highly customized bag has a padded front pocket and a padded larger inner compartment, plus a shoulder strap with padded shoulder pad.
Unique Jaw Mount with an included Riser means NO Loose Parts when deploying or disassembling the antenna.
