Aloha Jewel,
The Pakua mirror would be to circumvent the tower if it was a poison arrow looming in front of your front door. You can muscle-test to see if that is the issue contributing to your situation. It is not just about being an 8-sided mirror, so the cutting of glass suggestion isn't going to helping that case.
I'd dowse the place, and check into the EMF technologies out there to help dissipate the energy coming from the tower. There are a lot of items out there for this. Marie is endorsing a MEMNON system(http://www.mariediamond.co.uk/memon/), but check out what's out there and muscle check or use your dowsing rod to see if it will neutralize the energy of the radio tower before ordering (they tend to be expensive).
Much Love,
Shawn
