terminating resistors?

Hi Henry,
I homebrewed one a year ago, on the way to building a Rhombic (first half of my rhombic). It didn't do much for me in the way of excitement so I completed the Rhombic project and then only needed one terminating resistor. I was looking for a 500 watt 600 ohm resistor, and you are right, they aren't common items. I checked with a company called Carborundum I think it was, who make Globar resistors but they wanted something well over $100 for it. Had to get them to "quote" my request, couldn't get a price from their web site. So I looked for alternatives and an interesting alternative was to get a 50 ohm dummy load and use a balun (an un-un in the case of a vee beam since you are connecting to ground) like a 9:1 type to match the 50 ohms up to 450 ohms.


As to performance... that's another subject, that's not what you asked, is it?
