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.

BTW my 2m-8877 is capable of 2000w* RF output so pretty hard to find a dummy
load to take that.
