This isn t the ideal situation for installation of an outside antenna but sometimes it is necessary based on a number of factors.
Do you need to ground an antenna in the attic.
If you have no access it s hard for me to tell you to go to extremes to find a way.
However the connection of your antenna coax to various ac operated equipment in this case your converter box or tv introduces the potential of electric shock.
If you would like more information or need help installing your booster check out our support center.
In the case of an attic installation your tv antenna will be sheltered from the environment so there s no need to ground it for that reason.
But if you have access to a ground connection that can serve the attic splitter it makes sense to use it.
