High Gain 433MHz antenna with coaxial cable and SMA connector


To be used with 433MHz Gigalink Receivers

The ANT433M is a ground independent colinear antenna with 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. Its low VSWR and high gain makes this antenna suitable for applications that require extended range.
