172 MK2 Aerial question

[hkka]

I want to change to a shorter one. Some said Honda one can apply on Clio. But my experience is that Honda car's radio efficiency is not very good. For example, in the indoor parking lot. Clio can listen to the radio clearly, but Honda one are sucks!

Any other recommendation??? Any Ebay one are good?? I prefer black. Does the quality of the aerial really effect the radio efficiency???
