This 1:1 ratio current Balun is the best for feedline isolation and choking.
This Balun is perfect for feeding your 450 ohm ladder line from a ZS6BKW or G5RV antenna on the 50 ohm point.
Designed for those who want the maximum isolation and choking across the full HF spectrum. This Balun has two 2 cores in a stacked configuration to maximize choking impedance on HF bands from 1- 30MHz.
Transformation and power handling are excellent while providing a choking impedance that exceeds 8000 ohms.
Even on 160 m the choking impedance is 2000 ohms, and 3300 ohms on 10 meter.
Enclosure : Polycarbonate IP67, 100% UV resistant.
SO239 Connector : Silverplated.
All hardware Stainless steel.
