Overview Vehicle support solves the mechanical mounting problem, but the antenna must still use the correct base, radiator, counterpoise or vehicle return, and feed-line arrangement. Key Points Use a supported stationary configuration Verify bonding and coax routing Do not drive with a temporary portable assembly What to Do Next Identify the exact configuration and consult its current user guide before changing hardware or operating limits.

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.
