OMNI FULL-WAVE
SATELLITE ANTENNA
5000-0021
|
Ideal for Buoy
Applications
Maximum Gain at Low Elevation Angles
Optimum Performance at Higher Latitudes for Geostationary Operational
Environmental Satellite (GOES) |
APPLICATIONS
• Mobile Satellite Platforms
• Radiosonde Receivers
• Ideal for Transit Navigation Receiver Sites needing illumination
of multiple satellites
• High Latitude Geostationary Satellite Coverage |
| FEATURES |
| • Maximum gain at low elevation
angles - optimally shaped pattern for
maximum gain just above the horizon
(where path losses are minimal) |
| • Rust resistant w/sealed
G-10 fiberglass radome & a white
two part polyurethane paint finish
for long life under hostile atmospheric
conditions |
| • Improved performance
over the half-wave for all low-orbiting
satellite applications |
| • Optimum performance for
DCPs at higher latitudes & with
look angles above 45° elevation |
| • Hemispherically omni-directional,
full-wave quadrafilar helix antenna
with right-hand circular polarization |
| • Multiple satellite coverage
regardless of the position of the antenna |
| • Antenna pointing not
required since antenna is mounted vertically;
no additional alignment necessary |
| • Light weight, resonant |
| • Superior axial ratio,
SWR, & bandwidth |

| HELPFUL HINTS |
| • When
mounting an Omni antennas on a side
arm of a tower, do not mount the antenna
close to the metal structure. Place
the antenna at least three to four
feet from the side of the tower, more
if possible. This minimizes the distortion
of the antenna pattern allowing maximum
gain. |
| • To maximize the service
life of the installation, always apply
waterproof or antenna sealant tape
to the RF connector once the coaxial
cable has been connected to the base. |
