Recovery Procedure
To recover the Fan Dipole antenna, perform the following steps:
1.
Disconnect the Coaxial Cable from the Radio Set.
2.
Lower the BALUN.
3.
Disconnect the Coaxial Cable from the BALUN.
4.
Carefully roll (do not twist) the Coaxial Cable.
5.
Disconnect the Antenna Wires from the BALUN.
6.
Untie the Paracord from the Tent Stakes.
7.
Pull the Tent Stakes from the ground and place them next to the Coaxial Cable.
8.
Wind the Antenna Wires onto the Line Winders.
9.
Remove dirt from antenna components and inspect them for signs of wear.
10.
Store components together; ready for next antenna deployment.
Troubleshooting
Most problems experienced when using the Fan Dipole Antenna are likely to be caused by failures in the Coaxial
Cable or Antenna Wire connections. Perform the following steps to troubleshoot problems with the Fan Dipole
Antenna.
1.
Connect a Standing Wave Ratio (SWR) Power Meter and check the SWR on the lowest and highest frequencies
of both 40 and 20m.
2.
If the SWR is greater than 8.0 on the four frequencies measured in the previous step, ensure the Coaxial Cable
UHF Plugs (PL-259) are securely tightened to the UHF Sockets of the Radio Set and BALUN. Recheck SWR.
SWR readings lower than 8.0 on some frequencies indicate a tuning issue - perform the Field Tuning
procedure.
3.
Check the Antenna Wire Spade Lug connections on the sides of the BALUN to make sure they are tightly
connected and free from corrosion. Recheck SWR.
4.
Check for an open in the coaxial cable by temporarily placing the alligator clip from one side of a jumper wire
on the outside of the UHF-Plug (PL-259) and the alligator clip on the other side of the jumper wire on the
center of the UHF Plug. At the other end of the coaxial cable place, one lead from a Multi-Meter on the
outside of the UHF Plug (PL-259) and the other lead on the center of the UHF Plug. If the meter reads greater
than 0 (zero) Ohms (within the accuracy limits of the instrument), replace the coaxial cable.
5.
Inspect the entire length of coaxial cable and look for damaged cable (exposed shield material or pinched/
flattened cable).
6.
Due to the construction of the BALUN, it cannot be tested using a Multi-Meter as it will read as a DC short.
This is normal and does not indicate a problem with the BALUN.
7.
If still not operating correctly, contact Chameleon Antenna for technical support:
Please explain the problem and the steps you have already taken to troubleshoot the problem.
