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.
