B. National Radio R175A stacked bobbin HV plate choke with mounting
brackets and standoff insulator. Separate windings act as parasitic traps
for HF and WARC bands. Will handle 800ma.  $22 shipped

The R-175A predates the WARC bands. I believe the 'A' model was redesigned to work properly on the 'new' 15 meter band, but I might be wrong about this. In any event, I would not use a R-175A on WARC bands without first checking it for series resonances.
