best fm antenna for prton 300 radio

Hi im new here and Im looking for a great indoor fm antenna recommendation. Right now on my "vintage" proton radio setup I have a piece of speaker wire hooked up to my 300 ohm and get hardly anything.I live in chester ct and we are in a valley so reception sucks. I love my proton radio and dont want to go digital just yet because my favorite station are all in the low 90's.....so I want an antenna that works good,easy setup,and doesn't interfere with me using my laptop in the room(static). Any suggestion?something on ebay with a link would be great-
