DAB Sharkfin Vs Boot amplifier - Which provides better reception.

[Degudodger]

Undecided as to which DAB aerial i am going to use for, both are about the same price and effort, the boot mounted amplifier may take a little longer. I am happy to go with either option but in terms of signal strength which option is better - Shark Fin?

would be interested in the answer to this one as well.
I guess the boot lid DAB was for cars with no roof aerial?
general opinion seems to be a roof aerial should perform better as its higher and the metal roof helps "reflect" the signal.
If you just want FM & DAB, the polo roof aerial would be cheaper than shark fin, which has GPS and phone options?

I think this is the polo one, not sure.....
