2. Underneath that rubber cover you will find a screw, secured against the
antenna with a nut. By turning the screw counterclockwise, you can
lengthen the antenna for about 15mm. Using a 3mm hex Allen key (not
supplied), you can turn the screw.
3. Start with the the nut being as close as possible to the screws head and
the screw being all way in to the antenna.
4. Measure the SWR and write down that SWR value.
5. Now carefully turn the screw counterclockwise for a complete turn and
measure/write down again. By doing so, you will be able to fine tune the
antennas SWR.
As soon as you found the best position for the screw, secure the screw with the nut
against the antenna and put back the rubber sleeve.
