How Can I extend my FM transmitter range?

[flood1]

Hi there,
Actually, this is my first post here " Hope it to be the first step to the millions" :-[
I've constructed one project similar to those under FM transmitters in the website's project section and what I want to do is trying to extend the range. Should I have more power or play a little with the antenna?
Thanx..

The best way is to use a FM Linear like this:

Linear FM 30Watt : http://www.electronics-lab.com/projects/rf/010/index.html

This circuit connects to the output of your transmiter and it is able to make a 4-5W transmitter to 25-30W one.

Alternative you can use a FM antenna booster (active antenna) like this: http://www.electronics-lab.com/projects/rf/022/index.html

About the anntenas you can read this article: http://www.scott-inc.com/html/fmant.htm

Transmitting 30 watts without a license is probably highly illegal. A directional antenna can boost the signal without getting you in hot water. The ARRL antenna book is a good source of info.
