Re: Height above ground
- You might want to check on the Wellbrook site (www.wellbrook.uk.com).
They sell some very well regarded broadband loops and I believe that
they recommend that the loop not be placed to far above the ground.
They say that you get better performance out of the antenna if it is
no more than 6-12 feet high. It's more important to get it at least
15-20 feet away from the house and any other sources of RF
interference to keep things as quiet as possible.

- Yes, that sounds about right to me. I am going to grab the pictures
this afternoon and sketch the schematic this evening.
I realize this may be simple but loaded question, but is there a
consensus on whether or not I should replace the driven loop with small
diameter copper tubing. I have a quantity of it available.
