Hand held dipole a bit over engineered

This is an idea coming out from a video on youtube displayng an HAM got the dipole antenna from an old TV then build up something like this.

What is neeeded:

a couple of metal rods or better two telescopic stylus, cut the rod at right lenght dependig which freq. that you are interest for.
a plastic tube for the handle
some coaxial cable and a connector
a printer and a filament spool

The two halves of main body have inside a right space for hold what is needed and well cable and rods.

Put me a like o better tell me how it work your.
Ciao.

ps tnx to Sirio Sechi for the idea
