SABRE COMMUNICATIONS CORPORATION MODEL 800

GENERAL DESCRIPTION


BROADBAND DIPOLE ANTENNA - MODEL 800

picture Sabre Communications Corporation Model 800 THE SABRE COMMUNICATIONS MODEL 800 is designed to provide excellent performance for short, medium and long range circuits over a broad band of frequencies without the need for couplers or tuning devices. Design parameters were chosen to provide high take-off angles at the lower operating frequencies decreasing as the operating frequency increases.

At the lower operating frequencies where high take-off angles are present, the azimuthal pattern is essentially omni-directional. At the higher operating frequencies, the azimuthal pattern approaches that of a dipole.

Broadbanding has been achieved without the need of coupling devices or termination resistors, thereby retaining a high degree of radiation efficiency at all frequencies with simplified operation. No tuning or switching is required.

The two support towers are constructed of high strength steel angular legs and bracing. All steel members are hot-dip galvanized per ASTM A-123 specifications. When used with the optional hinged base and AEK erection kit, the total system can be assembled at ground level and raised to the vertical position without climbing the structures. No cranes or lifting gin poles are required. Once the structures are installed, the radiating curtain can be lowered to ground level independent of tower supports.

The radiating curtain and feedline are fabricated from alumoweld cable for high strength, resistance to corrosion, and high conductivity.
