Explanation
Overview An Inverted-V antenna is a variation of the dipole in which the center is elevated while the two ends slope downward toward the ground, forming an inverted "V." This configuration requires only a single center support, making it extremely popular for portable and field operations. Advantages Single support structure. Simple installation. Broad azimuth coverage. Excellent portable performance. Performance Compared with a perfectly horizontal dipole, an Inverted-V generally exhibits a slightly more omnidirectional radiation pattern while maintaining excellent overall efficiency. Installation Considerations Maintain adequate clearance above ground. Avoid sharp bends at the feed point. Keep wire ends safely away from people. Applied to Chameleon Products Several Chameleon wire antennas can be deployed as Inverted-V antennas using a single mast, tree, or portable support structure. Related Articles What Is a Dipole?

The exact result depends on the complete station: frequency, geometry, feed line, matching network, return-current path, environment, operating power, and the reference plane of any measurement. A low SWR establishes an impedance relationship at that point; it does not by itself prove efficiency, radiation pattern, compatibility, or safety.
What to Verify
- Use the newest official product guide or primary service documentation.
- Confirm the exact model, revision, components, configuration, and operating conditions.
- Begin tests at low power and change one variable at a time.
- Do not infer compatibility from connector or thread fit.
