Default Is there a proper way to use a telescopic aerial on a portable FM radio?

This may seem like a dumb question but I was wondering if there is a proper scientific way to achieve the best reception on a given fm radio station by adjusting the length and angle of the telescopic aerial? Usually I would extend it to its maximum length then move it around to get the best reception by trial and error. I have read that T shaped ribbon aerials can be tuned to get better reception on certain stations by shortening them. If I remember correctly the higher up the FM frequency the shorter the aerial should be. Does this principle apply to telescopic aerials or is it simply a case of the longer the better and adjusting the angle and position using trial and error?
