Description
This rugged antenna certainly represents the “State of the Art” in Ground Independent Antenna technology, providing a low angle of radiation. 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 fibreglass maritime vessels.
The ANT433MINI is a small a 15.5cm antenna, with a SMA termination at the base. It connects directly into the connector without any cables.
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 ANT433M comes with a gold SMA connection at the base.
The ANT433MSpring comes with a spring at the base, which makes it suitable to be used on moving, vibrating machines, cars etc.
