Well as snoranger pointed out... that antenna you showed us is a uhf antenna in 477mhz so it wont work for your needs.... at all...
I have no idea what the radio is for (in north america fm in that range is for music/news stations.) So here, fm antennas just aren't very big because they dont need to be. They recieve only and the broadcast stations are the ones that need the masive power. Where you are I assume 98-107mhz is used for something different?
There's a ton of good radio experts here but unfortunately not many from your part of the word. Give us some specs and details on the radio and what its used for and we can probably help you find the appropriate antenna.
