Fix ariel on nokia 3310?

Hi
Recently had my phone stolen so am trying to use my old Nokia 3310 for now but the back is missing off it tho the ariel cover thingy is still intact but wont stay on, I have some success with blue tack but only for a minute or two before the signal goes.. I know I am fighting a losing battle and will be getting new phone in the next week but really need to use phone this weekend, is there anything I can do about the ariel as a tempory measure? Thanks much appreciated,
