I agree it is prob 'overload' but thought perhaps notching might
work, i already have some really good multistage tvi filters but
wanted to be ready with a notch for when the building lets me into
the closet in case that is not enough.

My thought was to try and make stubs cause they are 'cheep' but
those links to the commercial site were pretty cool


Stubs work very well. You should try the single wire stub first.

You'll want good low loss coax. The better, the deeper the notch.

1/4 wave for the middle of the 2 meter band, and open at the end should
take out the 2 meter overload.

Anecdotally, I used a single stub during a contest to knock out overload
from 40 meters @ over a kilowatt. The antennas were around 50 feet away
from each other.
