Use a SWR meter

Its not hard to tune an antenna, provided that you have a SWR meter (and not an old CB one - has to be the right frequency for the transmitter which i presure is 88-108MHz) and also provided that the antenna IS tunable. Some people make antennas and whilst in the construction they purposley construct the antenna for a specific frequency ie. I constructed an antenna the other day, but it is only intended for about 106MHz and slightly tunable to +- 1MHz or so. Ie it will only go from 105-107MHz to get a good SWR reading.If you have some old antenna there are ways of re-tuning the antenna to your specific frequency by making the element longer or shorter, but this totally depends on the antenna type and construction.
Read up on antenna construction - try google.
Also I have plans for an antenna that kicks ass (well a bit anyway) if ya want em giz a shout.
Oh, and another thing, if you are tuning your antenna in, drop the power on your TX to about a quarter as this will help you NOT to blow your output transistor when tuning if things go badly wrong - as I did not so long ago when a wire came unsolderd in me antenna - KABOOOOOMMMMM
