BASE EMCOMM (EMERGENCY COMMUNICATIONS) ANTENNA FOR DIGITAL NVIS OPERATIONS

If you want a 100% American sourced 10 through 80-meter antenna from a U.S. company that is owned by an American, then this HF system is it.

SMALL WITH NO ADDITIONAL GROUND PLANE REQUIRED! This is the perfect antenna for boat or base installations without a lot of real estate or a ground plane that has a 1,000-mile coverage radius.

OPERATIONAL SPECIFICATIONS

The MIL-STD-188 M110a digital communications mode is rated at 25 watts continuous and bursts of 100 watts digital for up to 1 minute using the MIL-STD Data Modem Terminal (MS-DMT) and Automated Message Terminal (AMT) software applications.

EMCOMM DESIGN CONSIDERATIONS

A) Computer designed to maximize Q (efficiency)
B) Capacity Hat configuration to enhance your signals launch EMCOMM antenna patterns

PHYSICAL COMPOSITION OF THE SYSTEM

• 7075-T9 aircraft aluminum,
• Poly sheathed woven copper clad steel wire, and
• 316 stainless-steel.

INCLUDED EMCOMM COMPONENTS

• 1 Tuning match with Built-in SO-239 connector
• 1 Vertical Element made of 7075-T9 aluminum
• 3 Horizontal Elements made of 7075-T9 aluminum
• 1 NVIS 15 feet 4 inch element made of poly-sheathed woven copper clad steel wire and insulator

Base EmComm Antenna Analysis

Site Selection

Deploy the antenna at a site that is above and away from surrounding objects.

​Assembly

A) Locate the match and mount and screw the match onto the mount.

B) Locate the black MilStick elements and screw each element onto the match.

C) Install the mount on a 1.25-inch mast pipe.

D) Locate the wire element and secure it under the base of the vertical element above the match.

D.1) Deploy the wire element horizontally at approximately 180 degrees in the opposite direction of your coax.

E) Run a dedicated RF ground wire to your equipment (not to a shared AC ground).

F) Connect your coax to your equipment and to the SO239 on the match, ensuring that the coax does not coil up on itself.

GUYING: At your discretion, you may use your own guy ropes to secure the mast.

Learn More About EmComm Antennas

EmComm antennas are used by Amateur Radio operators (hams) for Amateur Radio Emergency Communications. Hams assist with maintaining communications before, during, and after declared emergencies, disasters, or planned Special Security Events.The field of Emergency Communications (EmComm) also includes the routine, daily communications of public safety agencies at all levels of government. This includes law enforcement, fire services, and emergency medical services.

Learn More about Amateur Radio EmComm operations

Amateur Radio operators have many informal and formal groups to coordinate communication during emergencies. These Include:

• Local and State Emergency Assistance and Traffic Nets

At the local level, hams may participate in emergency organizations, or organize “traffic nets” using VHF (very high frequencies) and UHF (ultra high frequencies). At the state level, hams are often involved with emergency management operations.

• National Emergency Management Services

In addition, hams operate at the national level through the Radio Amateur Civil Emergency Service (RACES) – which is coordinated through the Federal Emergency Management Agency (FEMA) – and through the Amateur Radio Emergency Service (ARES) – which is coordinated through the American Radio Relay League (ARRL) and its field volunteers.

• Emergency Weather Information

Many hams are also involved in SkyWarn, under the National Weather Service, and provide emergency weather information to the NWS for analysis and dissemination to the public using EMCOMM antenna, radio, and power that is off the grid.
