Some customers may want to install the antenna in their attic to avoid exposure to bad weather outdoors.
Yes, you can install the antenna in the attic, but your roofing material may weaken the signal strength. We advise for best results to mount the antenna outside. Check if the signal level is good enough for most of the channels before you install it in your attic.
You may expect the signal to be approximately 10-15% weaker than if installed outside.
