The main way in which my loop differs from your design (other than the
feedline asymmetry) is the fact that the shield is not cut away from the
center conductor opposite the feed input. Can you tell me what function
this feature serves?

Hi Dave,

It means there's a cognitive slip between you and Owen (and what is
generally constructed as a "shielded loop").

The cut-away is the feedpoint of the antenna. The two semicircular
sides extending away from it are the dipole arms (or the complete
loop, if you prefer), and the join with trailing feedline is just
that.

You would do well to more completely describe your differences as an
open must exist somewhere in the shield (yes, an irony for what is
called a "shielded loop") for it to work as an antenna.

Hey Richard,

Thanks for the quick reply.

When you say that the cutaway is the feedpont of the antenna, does that mean
it is where the received signal enters the antenna? And the feedline is
where it is carried to the receiver?

Many thanks,

Dave
