4. 80m operation is obtained by complete removal of the WANDER LEAD. It will also be necessary to use the
SPIKE to adjust for lowest SWR on the desired operating frequency. Check SWR with and without the FLY LEAD
plugged into the socket marked "FL." You must adjust the SPIKE for the lowest SWR on 80m. With the SPIKE set
at the scribe point, the resonant frequency is approximately 3.850 MHz. To raise the resonant frequency, push the
SPIKE in.
TROUBLESHOOTING
EXTREMELY HIGH SWR- Check all connections for opens, or shorts. Make sure the WANDER LEAD extends from
the WL socket for your desired band of operation. Make sure the WANDER LEAD is evenly spaced as it wraps around
the antenna, counter clockwise, from the bottom up. Again, remember, do not wrap too tightly. Also, remember that a
quarter wave vertical needs a large span of metal/ground beneath it to act as a counterpoise.
MODERATELY HIGH SWR - Make sure the antenna is not unusually close (parallel) to any metal, such as the trunk,
or side of an RV (see INSTALLATION). Recheck the integrity of your grounding. Try retuning the SPIKE at the desired
operating frequency.
Remember there are more important aspects of mobile installations than having a 1:1 SWR. It is okay and fully
acceptable if your SWR should vary from 1:1 to 1:8. Pay special attention to grounding and antenna placement.
CARE AND MAINTENANCE
All OUTBACKER antenna are fitted with a rubber "O" ring inside the tip to prevent water entering the mainshaft,
however condensation will accumulate on the inside of the shaft, do not be alarmed. This condensation will not harm
the antenna, nor will it cause inferior performance. Just remove the KNURLED LOCKING NUT and shake out any
water. Check your antenna after heavy rain.
To clean your antenna, wash it with warm, soapy water and wipe dry with a soft cloth. Apply a thin coating of non-
abrasive car wax. Buff the antenna to a shine. Do not use cleaners with an acetone base as this will strip the shiny
coating.
