MODEL-1942-1This 1942 NVIS compact, antenna is available in three separate models.

The 1942-RT (Roof Top) is designed for a semi-permanent roof top installation. Its small footprint (less than 50 ft. square) allows straightforward mounting on flat roof commercial buildings. Since it is designed to be mounted on existing roofs it does not require roof penetrations for installation.

The 1942-TA (Transportable Antenna) comes with ground anchors, and nylon bags which are easily carried to any cleared area for assembly. The TA antenna may be set up using non penetrating mounts when the ground condition does not allow for penetration. (Part Number: NPAM1942)

The 1942-GM (Ground Mount) antenna is essentially identical to the transportable version except it is meant for a semi-permanent to permanent installation. The anchors are more substantial and there is no carry bag.

All versions have stainless steel elements and ground radials. All have snap together aluminum mast sections that can be assembled on the ground and easily pivoted up to the erect position. The RT and GM systems utilize guy wires manufactured by Phillystran, Inc. using coated Kevlar® for maximum strength.

These broadband terminated center-fed antennas require no tuning across the entire bandwidth, eliminating the need for antenna adjustment or an antenna tuner.  A near vertical radiation pattern at frequencies below 10 MHz is ideal for reliable communications at 500 miles (800 Km). Lower radiation angles above 10MHz allow for reliable communications over much greater distances.
