Because resistance =! Impedance, at the resonant frequency of the aerial.

So what are you actually *supposed* to do with the earthing braid at
the aerial end of things? (My old Reader's Digest DIY book doesn't
mention the 'top' end of the aerial installation.)

You are supposed to clamp it under the saddle provided. The type of aerial
you describe is just a "contractor" type with no balun. I heartily
disapprove of those, due to the mismatch. You can get away with a great deal
when you have analogue TV, but you will find that once it is shut down, your
whole installation will need doing properly.

what would you recommend instead? Im about to put a new aerial system
in, and am in a poor reception area.
