Do shark fin aerials provide you with a decent reception or not? Thinking about replacing my aerial with one but wondered if anyone has already done this and would know if they have decent reception or not??

Worse than what your current aerial will get. Might be fine if you are in an area with good reception but might be very much a problem you have a weak signal locally

Thanks for reply. What's your opinion on the look of shark fin aerials? Good or bad?
