LOW PASS FILTER
L1 Coil 1.5mm wire, 8.6mm diameter
L2 Coil 1.5mm wire, 8.6mm diameter
L3 Coil 1.5mm wire, 8.6mm diameter
C1 27pF (Capacitor is part of divider)
C2 54pF (Capacitor is part of divider)
C3 54pF (Capacitor is part of divider)
C4 27pF (Capacitor is part of divider)
Caution: Do not change the pressure on the
dividers by tightening the divider screws.
Doing so will result in detuning the low pass
filter with resulting damage to the RF
amplifier due to mismatch.
