Aerial kinda not working

[GazWatson]

My car radio will work when im not driving but as soon as I start it comes on and off what ever channel I keep it on.
I notice my car hasnt got a aerial but it has the housing etc so maybe thats why?

What you guys think?

You`ve answered your own question lol.

either that or interference is getting in. is the small black capacitor still grounded on the coilpack?

If it's not the fact you don't have an aerial, there may be a loose connection somewhere that is only disconnecting when driving. That would be my next port of call, but it's probably the aerial.
