[Elecraft] Product Suggestion - 500W Dummy Load

[Wes (N7WS)]

I tested my amp (http://sadxa.org/n7ws.html#amp) with 150' of RG8 into a 
Cantenna (almost) submerged in a bucket of water.  Wasn't CCS but okay for my 
purposes.  Using the loss in coax for an attenuator isn't unheard of.

When I was still in the work force I once had to test some cables with 100 Watts 
applied at elevated temperature (+85C) and VSWR = 3:1 @10GHz.  For a load I used 
about four feet of 0.085" semi-rigid coax (3 dB loss) shorted at the end (6 dB 
return loss) coiled up in a can of water for a load.  An amazing tribute to the 
Hughes TWTA (and its circulator) that ran for over a hundred hours during this test.
