Purpose: When fully deployed with the NVIS element, the 6-80 meter directional antenna system can be 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. You may also use an external antenna tuner if your antenna is installed over a poor ground or not placed in a clear area.

Advancements over other manufacturers:
No changing of switches, jumpers or coils are required for touch free operations is something no competitor can claim.

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; The protective housing of the Alpha Match is made of 316 Stainless Steel, which outperforms the Black poly Delrin that is still popular with all other manufacturers. The inductor is now encased in a metal housing where it is isolated by a dielectric. This housing then enables the Alpha Match to capacitively balance the inductor once the elements are installed.

The MilStick Whip; The composite of the .433 inch diameter MilStick whip is a high strength, high quality, aerospace 7075-T9 alloy and at 13 feet is longer, has a larger diameter, & is stronger than any competitors whip. 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.

* Note - Add the HD-FMJ Tripod & get an upgrade to the Expedition Bag, both of which replace the lightweight aluminum tripod and medium field bag.
