Has anyone tried submerging MFJ Cantenna's into a water tank. I was thinking of building up some power dividers and running 4 of those cans in parallel to make a cheap high power load. One can will t

Could Nichrome flat wire be used as a dummy load if submersed in coolant? I know the resistance changes with wire temperature. Just a thought. Larry N5BIP ____________________________________________

Hey guys. The FCC has authorized the perfect dummy load. Since BPL has been shown to the satisfaction of the FCC not to cause interference, all you need to do is plug in your 20 kw rig into the BPL c

No, not directly, but VSWR didn't appear to change appreciably when I ran 1 minute key down test last week. This suggests that the resistor value remains reasonably stable. The oil gets damn hot, how

Dear Will, Some months ago Rich Measures was talking about ordering some special resistors from Ohmite or the-like to fill a need for a project he was doing. In that time I was bench testing the Emtr

Hal, I delved into this once using the large ceramic tubular resistors. They make there in almost any size. I have a air cooled load here that came out of a Harris piece of equipment. It has six 300
