I have used a 15 watt dry load @ 100 watts for 5 seconds without incident. It
is the model that Radio Shack sold approx. 10 years ago. It was also sold
under the Welz (sp) brand. In the specs it was rated for 100 watts for 10
seconds.
Good Luck,
Randy

Subject: [Amps] Derating Dry Loads
I have Bird 8173 Coaxial load rated at 300 watts continuous.
I'm not that familiar with "dry RF loads" and I was wondering if these
loads can be derated for brief periods of higher power like oil filled loads
can?
I'm thinking of 1500 watts of CW dots for 5-10 seconds? Just curious if
I should even try this, or maybe go buy a few hundred feet of RG-58 to put
in front of it...
Thanks in advance.
Mike K9MK
