Now there is a great idea and I have a 100' roll of RG-174 in the closet.
Sounds like a winner. It's a shame that we can't get parts like were available 30 years ago. I'd like to build some old design tube receivers and transmitters. I was born in 46 and just got a 1946 ARRL handbook off Ebay with a lot of things that look interesting. Thanks to everyone for their input on this matter.... and not one flame in all of the answers, that's rare on the user groups anymore! 73 to all, Ken, KC4IH "Dale Parfitt" wrote in message news:z4uAe.5729$Zy6.3230@trnddc04... "KC4IH" wrote in message ... I need to build a 3db pad, 50 ohm, 10 watt, to reduce the drive to my 6 meter amp. I need 2 X 300 ohms and 1 X 18 Ohm resistors and thought it would be an easy matter to find them with enough current rating to do the job but can't find anything larger than 1 watt carbon (not film, which are somewhat inductive ) resistors. I can find want is called non-inductive wire wound resistors. I can't understand how a wire wound resistor can be non-inductive. Could someone explain this? Wind up approx 40' of RG-174 into a small coil and tie wrap it. It will handle 100W + at 50 MHz and have a great return loss. Lots easier than fooling around with resistors of questionable characteristics and heating problems. Dale W4OP |
