Hi guys!

I live on the 23rd floor of a building so I can't use the earth directly for
the ground.
The options in my "radio room" are the ground from the electrical sockets
and that's about it.

I've heard I can roll out 10ft of tin foil on the floor as a ground {that's
out}, or, use the window frames as a good ground. As far as I can tell, the
window frame looks to be aluminum or some sort of alloy.

Have any of you heard of using a window frame as a ground? I think I read it
in this NG that someone recommended it and was using it for his ground. I've
been using the ground from an electrical outlet.

But being that so many people live in the building that use appliances and
other plugged in items all day and night, I sometimes get what seems like
bad feedback affecting the receiver.

So what do you think of the window frame for the ground then? I welcome any
other options I can use in a room very far from a direct earth ground. The
bathroom pipes are all the way across the room separated by a wall. Not easy
to get to.

Thanks for any help
Lucky
