Depending on your definition of reasonable, try your local branch of
Richardson Electronics - www.rell.com or - BFI Ibexa for Anaren or RF Power
products. These are V/UHF resistors with stripline tabs for connection.
At similar prices but possibly easier to buy there's a variety of thick film
power resistors made by Tyco (used to be CGS) and Vishay. I've not tested the
high power ones, but I imagine they are effectively non-inductive at hf. You
can find data at www.farnell.co.uk and then search.
