The Hy Power BL 10-160-5KW is a high power, 1:1 current / choke balun for 160 through 10 meters. It has an SO239 connector to accept your coax. This is a very efficient balun that has a low permeability, less lossy ferrite than most other baluns on the market today. Less losses means less heat on the ferrite material, less chance for balun failure and more power delivered to the antenna.
The power handling capability of this balun is phenomenal. It is conservatively rated at 10 KW on 160 meters and 5 KW from 80 to 10 meters. These ratings are good for up to 2 to 1 SWR.
The MIL-SPEC transmission line used to make the balun uses: silver clad copper center conductor, silver covered shield, solid Teflon dielectric with a voltage rating of 1900 rms volts and temperature range of -55 to +200 degrees centigrade.
The balun is enclosed in UV rated material. The hardware is stainless steel so NO rust! There are also two drain holes in the bottom of the enclosure should any water migrate its way inside the enclosure.
Keep that RF off of the outside of the transmission line and delivered to the antenna where it belongs!
