flood Posted August 12, 2003 Report Share Posted August 12, 2003 Hi there, :o 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.. Quote Link to comment Share on other sites More sharing options...
mixos Posted August 19, 2003 Report Share Posted August 19, 2003 The best way is to use a FM Linear like this:Linear FM 30Watt : http://www.electronics-lab.com/projects/rf/010/index.htmlThis 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.htmlAbout the anntenas you can read this article: http://www.scott-inc.com/html/fmant.htm Quote Link to comment Share on other sites More sharing options...
russlk Posted February 13, 2004 Report Share Posted February 13, 2004 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. Quote Link to comment Share on other sites More sharing options...
