80m Band: Deploy all 3 ground grid sections fully. Retract the whip antenna completely, then pull back 1 section + 13cm (any section works). Position the sliding contact on the red coil within the gray-marked area (ensure the contact spring does not touch adjacent coils).
Frequency: 3.550 MHz ^^
SWR:
1.5: 1 2.
40m Band: Ground
grid length: 8.25 m (excess wire coiled on the terminal end using a winding board). Retract the whip antenna completely, then pull back 36cm. Position the sliding contact on the red coil within the gold-marked area.
Frequency: 7.070 MHz ^^
SWR:
1.5: 1 3.
20m Band: Ground
grid length: 4.2 m. Retract the whip antenna completely, then pull back 3 bottom sections + 27cm. Position the sliding contact on the red coil within the white-marked area.
Frequency: 14.200 MHz ^^
SWR:
1.5: 1 4.
17m Band: Ground
grid length: 3.2 m. Retract the whip antenna from the bottom: 6 sections + 18cm. Position the sliding contact on the red coil within the white-marked area.
Frequency: 18.120 MHz ^^
SWR:
1.5: 1 5.
15m Band: Ground
grid length: 2.6 m. Retract the whip antenna from the bottom: 7 sections + 25cm. Position the sliding contact on the red coil within the white-marked area.
