For a 10W load, it is hard to beat the OHR kit. It is just two resistors on the back of a connector, but you probably couldn’t buy the three components for $11.50. The Craddock resistors are almost $10 each in small lots.
"The CQC RFL-10 Dummy Load Kit consists of two 5 Watt 100 Ohm metal oxide resistors connected in parallel, giving you a nice non-inductive 50 Ohm DC resistance. We've field tested these babies and they produce a remarkably flat 1:1 SWR from 1.8 - 30 MHz. The main body of the RFL-10 is an S0-239 coaxial socket which allows you to create a nice in-line package. Two sturdy adapters are included, one that allows you to connect directly to an SO-239 coax connector, and another that allows you to connect to a BNC socket. There are two solder connections, and that's it. When completed the RFL-10 will dissipate 10W continuously, and up to 25W for brief periods." http://www.ohr.com/rfl10.htm <http://www.ohr.com/rfl10.htm> wunder K6WRU Walter Underwood CM87wj http://observer.wunderwood.org/ (my blog) > On Dec 27, 2016, at 12:21 PM, John Parker <johnj...@verizon.net> wrote: > > The good non-inductive resistors are made by Caddock Electronics.
