The round one only takes a set of 3 rollers to bend the re-rod into a
nice circle. Then weld ends together.  Build concentric circles, wire in
vertical members then weld, add circle sections, weld in cross pieces
and it's done.   Not as easy to do down in the hole and if it's round
and deep that sucker can get heavy to assemble and then lower into the hole.

It is in Michigan as well, but one *local* ham beat a ticket for having
one as he claimed to be monitoring harmonics from his UHF transmitter.
A bunch of members from the local ham club turned up at the trial as
witnesses to verify that.  We are now exempt for scanners too.

I understand some states give tickets if your mobile rig can listen on
police frequencies.
