includes a clutch to prevent damage, you
should not force the knob past the stops.
4.
Ensure your transmitter is set for no
more than 5 Watts during tuning.
5.
Transmit a carrier and gradually turn the
Tuning Knob counterclockwise and then
clockwise, around the highest receive
signal point found in step 3, to obtain the
lowest SWR. An SWR of 3.0:1 or less is
satisfactory. Your hand may slightly
influence the resonance of the loop
while turning the Tuning Knob. This is
completely normal, and you may have to
“touch up”
the adjustment slightly. The
bandwidth of the loop at 60 meters is
only 8 KHz, so once you are close to
resonance, make only the slightest of
Tuning Knob adjustments.
6.
Increase transmitter power to no more
than 25 Watts, see specifications.
Disassembly
1.
Disconnect Coaxial Cable and neatly coil cable.
2.
If used, disconnect Flexible Radiator Loop, carefully coil loop, and secure with attached sticky strap.
3.
If used, disconnect Flexible Radiator Loop Extension, carefully coil loop, and secure with attached
sticky strap.
4.
If used, detach the Flexible Booster Loop and secure pieces with attached sticky straps.
5.
If used, un-attach the Rigid Radiator Loop. Re-install the hardware in the Rigid Radiator Loop
flanges, so they do not get lost.
6.
Fully collapse Telescoping Mast.
7.
Remove Coupling Loop from the Telescoping Mast.
8.
Remove the Telescoping Mast from the Tuning Unit.
9.
Clean and inspect antenna components and then place them into the Duffel Bag.
10.
The antenna is now ready for transport and storage.
Troubleshooting
1.
Ensure the loop is away from metal surfaces. Sometimes simply reorienting, relocating, or elevating
the loop around two to four feet higher will reduce the SWR.
2.
Ensure Radiator Loop Connections are securely tightened.
3.
Inspect Flexible Radiator Loop for damage. Replace if damaged.
4.
Ensure the Coaxial Cable Connection is securely tightened to the Loop Connection.
5.
Inspect the Coaxial Cable Feedline for cuts in insulation or exposed shielding. Replace if damaged.
6.
Ensure Band Switch is set for your frequency range.
7.
Turn Tuning Knob fully counterclockwise.
8.
Slowly adjust the Tuning Knob over entire range listening for a marked increase in received signal
strength and receiver background noise.
9.
If still not operational, replace the Coaxial Cable Feedline.
Most problems with antenna systems are
caused by the coaxial cables and connectors.
10.
If still not operational, contact us for technical support.
