MITSUMI
Trackingless Type, For AM/FM 2-Band, AM Wide-Band
20 mm, PVC-2LHT-L5, -2LHT-LD5
FEATURES
It is a trackingless POLYVARICON for exclusive
MW use. It is wide-band use as the standard 20
mm product. It is suitable for use in practical
radios, since it is a model that has pursued high
cost-performance ratio.
