Instead, integrate the sign into the blinds themselves. Like, cut the sign into strips, then adhere the strips to the individual blinds so when the blinds are closed, it forms the image of the sign in the window.
Alternatively, paint the message on the inside of your blinds.
Either way, you're no longer displaying a "sign." Instead you just have decorative blinds.
Else fails, threaten to erect a 40 foot HAM radio tower.
Stop displaying the sign.
