DC Ground Type Antennas


DSHIDS

Question

DC ground type antennas show continuity between center pin and shield as a J-Pole does. My question is what type of polyphaser is used on DC ground type antennas? DC Pass or DC Block? Also what type is a Comet CA-712EFC collinear? Are collinear antennas DC ground type? Confused on DC pass Vs DC block polyphasers. Forgive my ignorance, and thanks for your help

Based on this white paper I believe you would want DC Block:
