A:Answer I can’t help with dB signal strength, but for me, this antenna was not worth the expense.
1. It did not work indoors at all
2. When I placed it outside, it lost signal every time a vehicle passed in front of my house. I was only able to place the antenna about 6 Ft above ground because after seeing how it performed, I didn’t want to waste any more time mounting it higher.
It may work well for others, but I wouldn’t recommend it.
