Analysis

Analysis at the antenna when properly deployed on the tripod with Vertical, NVIS, & Grounded Counterpoise elements without a tuner. An external antenna tuner can be used if the antenna systems is deployed over a poor ground or not placed in a clear area.

Deployment

1) Install the match on the Tripod or Mast Mount, your mounting option with the 8’ ground wire between the match and either the tripod or jaw mount.

2) Clip the 8′ Grounded Counterpoise Wire under and the 25′ NVIS Element above the AutoMatch. This will require that the clamps be pressed onto appropriate bend out for a perfect fit.

3) Attach your coax to the SO239 on the AutoMatch and connect the other end of the coax to your equipment.

More Information

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

Signal Pattern: Using the NVIS, Vertical & Grounded Counterpoise elements, the balance of the system launches 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.

No Guying: The HD Tripod wraps around and protects the antenna system when stored. Talons and a built-in heel step are at the base of each tripod leg. This enables the tripod to be used in most environmental conditions without guy wires.

Touch free operations: The system enables you to switch bands or change frequencies without having to change switches, jumpers, or coils as it is an off-center fed dipole type vertical that is pre-tuned when deployed over real ground. Making this antenna especially useful if you have a disability such as being mobility or sight impaired.

Increased ERP (Effective Radiated Power): The electrically balanced OCF dipole circuit of the system has an increased ERP over the base fed vertical (end-fed) antennas that use lossy matches to force low SWRs.

Optimized DX and NVIS signal patterns: The combination of a Vertical element with the NVIS and Grounded Counterpoise elements provide for a directional portable HF antenna system that enhances lower take off angles for increased DX communications, while simultaneously enhancing NVIS (Near Vertical Incident Skywave) for stateside communications.

Stability: The AutoMatch is computer designed for proper balance. It contains a transformer that is enclosed in a rugged housing. The match and elements are what give the AutoMatch both the inductive and capacitive balance. Once the elements are installed, their capacitive characteristics also enables RF to radiate.

MilStick Whip: This antenna is our electrically conductive, industrial strength MilStick whip. The composite of the MilStick whip is a high strength alloy. The construction of each element has a scratch-resistant surface. The inserts are then electrically bonded, where full RF continuity is used to ensure that maximum efficiencies are achieved. This Seven section MilStick vertical element that is 9′ 4″ long is excellent for most deployments in environments that are not exposed daily to salt water or extreme physical abuse. An optional stainless-steel whip is available for saltwater environments.

Industrial Wiring: Sheathed memory free wiring is used, which is rated for temperatures from -40°C to +175°C. This makes it far superior to wiring that is so light duty that it can be wrapped around a kite string holder.

Field Bag: The various sized field bags for our portable HF antennas include our logo and high-quality zippers.

Options

SS Vertical Element

1) The 17’ 9” stainless steel ‘SS’ vertical element is better suited for extended outdoor use or saltwater environments. The length of this whip can also be adjusted to achieve lower SWRs. Be advised not to deploy the full length of the stainless-steel element to 17‘9“ when it is used during high winds, but only extend it to 13 feet will provide better wind-load capabilities.

NOTE – If you are going to experience wind’s greater than 45 mph, then the element should be retracted. Alternatively, you can fully extend the telescopic whip when winds are less than 45 mph when guyed.

4 (four) 35′ NVIS elements:

Deploy using 1 (one) Vertical Element, 1 (one) grounded counterpoise, and the optional 4 (four) NVIS Elements each at 90 degrees from the other in lieu of the single wire NVIS element.
HF Frequency Coverage – 1.6MHz to 30MHz when using a tuner if ground conditions are poor.
Power – 250W PEP SSB, 125W CW, or 25W for digital modes

Optional end-fed elements

Use the optional 34′ (60′ or 140′) end fed element and Nut/Bolt – Alpha Antenna in lieu of both the vertical and the single wire NVIS elements.
HF Frequency Coverage – 3.5MHz to 30MHz without a tuner with the 60 foot element. Use the 140′ to increase efficiencies on 80/160M or the 34′ element for reduced efficiencies on 6-80M.
Power remains – 250W PEP SSB, 125W CW, or 25W for digital modes for all variations.
