Aero Band Antenna
[SXO-1503 117.9 - 136 MHz. 3dBd. Gain]
GENERAL:
 The
SXO-1503 Aero Band Antenna is a robust antenna with low VSWR and high gain covering the
entire band from 117.9-136 MHz. It can be mounted on top of an antenna-tower for a Omni
directional pattern or side mounted for an offset horizontal radiation pattern.
DESIGN & CONSTRUCTION:
The SXO-1503 Aero Band Antenna consists of two folded dipoles stacked vertically. The
antenna maintains constant gain and VSWR over its bandwidth of 10 MHz., making it highly
suitable for single or multi-frequency systems. The feed ends and cable connections to the
dipoles are sealed in epoxy at the end of the boom for protection against weather and
imparting rigidity and strength to the dipole structure.
This Aero Band Antenna operates at D.C. ground for protection against lightning and
immunity to noise. The dipoles are mounted on a tubular boom made of high strength
aluminum alloy, which offers a low resistance discharge path. Molded phasing harness cable
joints and N-Female antenna termination connector ensures complete waterproofing and many
years of maintenance free operation.
RADIATION PATTERN:
When the two dipoles are arranged 180 degrees apart around the central mast, 3dBd. Omni
directional radiation pattern results. Aligning the two dipoles collinearly a 5dBd. offset
radiation pattern is obtained. The radiation pattern can be changed in the field by use of
common hand tools.
PHASING HARNESS:
Specially designed center fed phasing harness ensures equal and in phase signal
distribution to both dipoles. All power splitter joints are molded to avoid use of
connectors/adapters for waterproofing and to minimize loss.
SHIPPING:
For ease of handling, the 12 feet long central mast for mounting the dipoles is shipped in
two sections of 6 feet each. It can be assembled with simple hand tools in the field with
specially designed center coupling supplied with the antenna.
