any wire is an antenna. good for you for trying.. and the only shortcoming of POS wire is it tends to stretch with time and heat.
you can make a dipole by using any insulator in the center.
cut up old computer firbeglass cases, throw away printer covers etc.
plastic windows in printers.
buy a sheet of 1/4 inch plexy at ACE or home depot.
or 1/8 inch plexy and hot glue two or three pieces together.
a good trick is to use several 'black' zip ties to hold a short piece of
1/8 in rubber auto hose to the center insulator and tape to the lead as a strain relief...
other wise the lead will break on one side and antenna acts funny and a dipole cant be checked with an ohm meter like a closed loop beam can sometimes.
use pulleys on the ends so you can raise and lower two dozen times to get it right.
have fun.
