“Today on Hamradiocomms I review the excellent MFJ-911H Current Balon. Handles 160-10 meters 300W and has switchable 1:1 or 4:1 baluns. Makes possible tuning random wire, ladder line antennas, other end fed antennas and dipoles.
Excellent all around, for portable or indoor use only, not weatherized for keeping outside.
