Hi Bill,

No cats here, so that's not a concern. Have thought of hemming a metal bar against the bottom of the Veilshield so that it lies flat against the window frame.

We're getting readings outside between 1.5 m/W2 to 4 m/W2; inside the house, the bottom floor ranges from 0.5 m/W2 to 12 m/W2, and the top floor ranges from 2 m/W2 to 21 m/W2. There seem to be hot spots.

In the adjacent studio where we work, a larger building and in front of thebedroom in relation to the antenna, we're getting on avg 8-14 mW2 downstairs and 20-60 m/W2 upstairs.

The antenna is above us in elevation, 650 meters away. Since the readings are so much higher upstairs, I'm guessing Yshield on the ceilings will help a lot.

I don't think our outer wall is conductive at all (We're painting on the inside). We're shielding just the bedroom first and will see how that goes with YShield/Veilshield. We're taking readings with a 3-axis RF meter.

Best,

Edo
