Hi,

I friend of mine, ham, is handicapped and cannot move without his wheelchair
He experiments QRM on low bands 160/80/75m induced by the fence installed by
his neighbor
I don't know what kind of fence it is, and if it is really close to his
house or miles away...

He would like to know if a rotaty loop antenna could remove this QRM ?

Yes, if it's from a single source, and it will also tell him which
direction it's in. Well, it's bidirectional, but common sense will
tell which way it probably is, if you already know about the
fence...But yes, most likely a small loop would take most of it out.
Maybe even all of it. The nulls on a good balanced loop are sharp and
deep. I know my loops can take a single noise source right out of the
picture. Or an undesired station for that matter if it's ground
wave... MK
