May I suggest my "Bucketenna" (tm)
One of those "15W" finned Radio Shack dummy loads will stand
100W continuously, or at least for quite a while (hours)
IF operated at the bottom of a bucket of water.
Use rubber tape to seal the connector...sold as
3M splicing tape at Lowes, etc.
Feel the water once in a while, stop if it gets warm.
If you don't want to wait for it to cool, dump it in the
garden, and refill with fresh cool water. I never did
discover how long it took to warm a 5 gallon
bucket with only 100W.
NOTE: if you move the rig, and don't notice that this
action pulled the dummy load out of the bucket, then it may
not survive. Gee, wonder how I know that? Anybody want to
buy a genuine SO-239 with integral finned, anodized aluminum
open circuit....plastic dielectric only slightly melted!
Oh well, at least it gave me a reason to fix the broken strap
on my "Cantenna"....trust me, water is much less hassle than oil.
Alternativly, a 75 or 100W light bulb offers fairly modest
SWR, though it radiates a little better than a "proper" dummy load.
YLBMV.
