Q - The most inexpensive way to shield my house, is there some kind a Program with waves that can shield a whole area
A - Hello
There is not cheap or easy way to protect your home.
First you need to get an EMF meter and use it.
Find the RF sources in side your house and remove them .
Find safety distances from ELF sources.
Find penetration points from outside the house and use the right RF protection to block it.
