If your Butternut antenna is experiencing intermittent operation with sudden SWR fluctuations and reception issues, the cause may be loose connections in the feedline or matching line. Check and secure all connections to resolve this issue.
Why is SWR high on some bands with Butternut antenna?
If you are experiencing high SWR on some bands with your Butternut antenna, ensure it is installed according to the instructions. Also, check the connections to the radials and ground system, keeping this connection within 6 inches or less.
What to do if Butternut BUT-HF9V Antenna doesn't tune 80 meter or 160 meter?
If your Butternut antenna doesn't tune to 80 or 160 meters, despite having properly installed radials, it may be significantly out of tune, possibly due to not following the systematic tuning procedure. Begin with the suggested settings in the instructions and create an SWR chart to pinpoint the point of resonance.
What to do if Butternut antenna was installed on the ground and tuning changed?
If your Butternut antenna's tuning has changed over time after being installed on the ground, install the radial system as per instructions and check the connection to the radial system.
What to do if Butternut BUT-HF9V displays degraded performance?
If your Butternut antenna shows degraded performance after a long period, perform routine maintenance at intervals, according to local conditions.
How to fix high SWR on 20 meter with Butternut BUT-HF9V?
To address high SWR on the 20-meter band with your Butternut antenna while other bands are functioning correctly, consult the instructions for tuning and radial information. Install a matching line using RG-11 75 ohm coax, ensuring it is 11 feet 4 inches if solid dielectric or 13 feet 6 inches if foam.
What to do if Butternut BUT-HF9V insulation arcs over?
If the insulation on your Butternut antenna arcs over between the 80-meter and 40-meter coils, potentially damaging the fiberglass, this could be due to operation at high power levels in areas where salt or pollution deposits have accumulated on the insulators. Keep insulators clean through routine maintenance.
What to do if high SWR occurs when high power is applied to Butternut BUT-HF9V?
If the SWR on your Butternut antenna increases gradually when high power is applied, accompanied by heating of the 200 pF capacitor, the suggested solution is to replace the bad ceramic capacitor.
Why is SWR high on Butternut antenna when roof-mounted?
If you're experiencing high SWR on one band with your roof-mounted Butternut antenna, even with radials in place, try tuning the radials and/or rerouting them away from metal.
How to fix few or no signals heard with Butternut BUT-HF9V Antenna?
If you are experiencing few or no signals and the bands seem dead with a very high SWR on your Butternut antenna, look for an open or shorted feedline, an open or shorted matching line, or a broken connection at the base of the antenna (feedpoint).
