Be very careful - keep your FM transmitters under the Part 15 limits or you might get busted! Putting a big antenna on even a low power unit will exceed the allowed limits
Here's a link to some very stable, PLL synthesized FM transmitter kits. http://www.dckits.com/index.htm I recommend the mono version if still available for best range. This is true of all broadcast FM operations - the presence of the stereo signals will cause a loss of about 20 dB of signal-to-noise ratio on the demodulated audio as the radio kicks into stereo mode. This is particularly troublesome on a weak signal. If the mono transmitter (which was cheaper is not available) the stereo choices are good too. I cover my whole property with a short wire antenna stretched out of the transmitter chassis. Steve WD8DAS [EMAIL PROTECTED]
