I built a duct tape/copper tape 2m band j-pole antenna today that seems to work great. I managed a 1.2-1.4 SWR across the whole band. Attached photo shows it hanging in the corner of my office above my desk. I used my NanoVNA to find the feed points. Attachment of coax is via neodymium magnets with bolts through them. Ideas all from various YouTube channels. Fun! #HamRadio #AmateurRadio

A strip of duct tape hangs in the corner of an office. The tape is actually an antenna.

The book titles visible in your first photo seem very appropriate for this project!

Construction is two pieces of duct tape attached with sticky sides together. Copper slug tape is the antenna and attached to the duct tape with its own adhesive. You can actually roll up the whole antenna because the feed points are detachable.
