Topband: Source of terminator resistors for EWE's?

[Eric Rosenberg]

I'm confused as to what I should or should not use at to terminate my 
three soon-to-be-going up EWE's (840 ohms, according to the QST 
article).

Any help on type and source is appreciated. Something simple. please... 
no need for a fancy box, I suspect.

Thanks and 73,
