For $29?  Maybe a home brew antenna with better patterns and maybe
even nulls aimed at nearby transmitters.  It is surprisingly easy to
build a helix antenna.

A notch filter can also be constructed to notch out the jammer if it
is out of band.  A "twin T" design might be  effective and low cost

Microwave is line of site so maybe just a meter plate that blocks view
of the transmitter.

The solution for a fixed timing receiver will be much easier than for
a mobile GPS receiver.
