Stubby aerial

Hi,has anyone got a link to a good stubby aerial for a Renault Clio RS 200 /2011,just brought one (65mm) off of eBay ,looks crap,rubbish fit and bad reception,looks like a pimple on a rock as it doesn't fit flush at the bottom.
 
That my stubby aerial just off ebay picks up radio fine but like you said it didn't thread all the way down so I just cut the thread down slightly imagejpg2_zps899e1d8c.jpg
 
Yeah ,I cut the thread down to about half and still doesn't sit good.Might cut a bit more.
