http://www.arivv.it/baluns.html WebEven at high SWR levels, the W2DU Baluns won’t generate harmonic radiation. The internal feed line passes through ferrite beads which prevent RF current from flowing on the coax shield. Two 50 ohm 1:1 models are available; HF (1.8-30 mHz) and VHF (30-300 mHz). At 10 mHz, the HF model handles over 10 KW PEP at VSWRs up to 2:1.
