Ariel Advice

[partybish]

Hi Guys,

I have a stubby aerial on my HDI which doesn't fit very well (the screw isn't really long enough) and I have no radio reception!  It looks a bit like this one - stubby aerial

I also have an aftermarket Pioneer headunit.  I've been reading a few threads that say aftermarket head units will cause poor radio reception but I can't tune to any channels whatsoever - all I get is static.

I bought this Whip Antennae Mast aerial which said it worked on a 306 but the screw was too narrow to fit.

I've since seen a few aerials on ebay:

This is supposedly a Genuine Aerial Mast  but it's quite long and I'd prefer something shorter as I might end up fitting roof bars.

I also messaged this seller about this advertised as a Genuine Sports Style Aerial and was told this is a standard fit on all 306 models after 1/12/1997.

Does anyone have any experience of which aerial will fit and provide decent reception or is there something more complex I need to do given the aftermarket HU?

Cheers!
