Indoor 450mhz antenna

[SCPD]

Looking for idea/plans for an indoor 450mhz antenna. I have a mag mount with a big metal ground but that is unsightly. I have a j pole or two already but wonder what other people have done

Thanks

Build a Slim-Jim out of 300 ohm ladder line. About a foot long or so. I built one... works great.

A quarter-wave ground plane can be made out of a panel-mount SO-239 connector. They are cheap and not hard to make. The one linked below uses a panel-mount N connector, but the idea is the same. I'm in the process of making some for my scanners.
