I have looked around on Google without much success. I am interested in
making my own indoor antenna for my scanner. It must be general coverage
and
omni directional. I have wire and coax. Just looking for something that
is
going to be better than the telescoping antenna built into the scanner
without going outdoors. If anyone has any ideas or links for websites
with
some info on building your own indoor antenna please share 
Thank You and Best Regards
