TROUBLESHOOTING
Check out your installation again, looking for loose connections and checking all
dimensions. Then refer to the list of possible symptoms below:
Symptom: Few or no signals heard: bands seem dead , SWR is very high.
Look for: Open or shorted feedline, open or shorted matching line, broken
connection at base of antenna (feedpoint).
Symptom: High SWR on 20 meter; other bands OK.
Look for: Missing matching line. Antenna not properly tuned. 20 meter radials
not present or wrong length. Consult instructions for tuning and radial
information; install matching line RG-11 75 ohm coax, 11 ft 4 in (345.4
cm) if solid dielectric, 13 ft 6 in (411.5 cm) if foam type .
Symptom: High SWR on some bands, but signals heard on all bands (conditions
permitting).
Look for: Missing or defective radial system. Install as per instructions and
check connections to radials and ground system. Keep this connection
6 in or less.
Symptom: High SWR on one band when antenna is roof-mounted. Radials are in
place, but antenna will just not tune.
Look for: Radials of wrong length or running close to metal rain gutters or roof
flashing. Tune radials and/or reroute them away from metal.
Symptom: Tuning is sharp with narrow bandwidth on 80 meter (and 160 meter if
TBR-160-S is in place).
Look for: Normal condition. The total length of the antenna represents such a
small percent of a wavelength on these bands that sharp tuning is a
normal condition.
Symptom: Antenna was installed on the ground and tuned OK, but tuning changed
over a period of weeks or months.
Look for: Antenna installed over poor ground system. Ground conditions have
changed, causing shift in resonance. Install radial system as per
instructions. Check connection to radial system. When you see this
problem, you may assume that a ground rod without a radial system is
not enough.
Symptom: Resonant point changes during wet weather.
Look for: Normal condition.
Symptom: Insulation arcs over between 80 meter and 40 meter coils damaging
fiberglass.
