ANT433S, ANT433S-SMA, ANT433M, ANT433MSpring
433MHz 50 Ohms Antennas
Features
• 4 versions - ANT433S (35cm), ANT433S-SMA (35cm), ANT433M (94cm), ANT433MSpring (69cm).
• This half wave coaxial dipole is completely ground independent.
• The term ground independent relates to its ability to be completely independent of the need for negative grounding. (Earth)
• This feature allows the antenna to work efficiently in a wide variety of applications, from its probable use on motor vehicles to one of more difficult installations such as on fiberglass maritime vessels.
• All brass and PVC construction provides complete environmental and weather protection in the field. Optional Stainless Steel bracket included.
• All Stainless Steel & Brass
• Full 6dBi gain
• Low SWR ( no tuning required )
Application
For use with Elsema UHF transmitter and receivers

Description
This rugged antenna certainly represents the “State of the Art” in Ground Independent Antenna technology, providing a low angle of radiation with a minimum of 6dBi gain.
The ANT433S-SMA comes with a gold SMA connection at the base.
The ANT433M whip section is a sturdy antenna that will remain vertical at high speeds and is ideal for applications that have little or no ground plane area or applications that require a rugged durable antenna, i.e.: Industrial, Mining, Heavy Transport etc.
The ANT433MSpring comes with a spring at the base, which makes it sutiable to be used on moving, vibrating machines, cars etc.
NOTE: If mounting the antenna on a Bull Bar the antenna is recommended to be fitted with the optional “SAURF” spring to give extra gain and strength. Spring mount available upon request.
