This could be a whole 'nuther thread. For a reference, I don't have
any difficulty making a 50 ohm load with 40dB return loss out to a GHz
or so for less than $10, and most of that is the connector. Does
someone need to document how to do that? But I submit that if you
want accurate SWR measurements on a particular line, you should
calibrate your SWR meter to that line, and that doesn't take any
reference except the line itself.

Cheers,

But can you make a 50 Ohm dummy load with those specs that can
handle
300 Watts? The stays at 50 Ohms out to at least 200 Megs or so?

And i'm still not sure what you mean by "calibrate your SWR meter
to the line". All the SWR meters i have seen are all for 50 Ohms.

Could you tell us the exact procedure?
