You're planning to run it through a standard 120V house circuit when it's designed to run off a 12V car circuit?

If you want some easy +50metres of coverage put a better antenna to it, like a long piece of electrical wire smoething like 2meters or something. And if that is not enough, make a proper half-wave dipole and feed it with some proper coax.
Google will thell what those things are.

If you open the transmitter up, there should be a short piece of usually white wire that is connect only at one end.
Scrape some of the insulation off to expose the copper at the un connected end. Attach your antenna wire.
And PooF! you got more coverage.
A better antenna is not called "the poormans amplifer" for no reason :p

I can't find the antenna wire on my transmitter. I found a wire labeled ANT but it is bunched together with the wires L and R (guessing left and right sound) and a GND wire which I have no idea what it means. All for wires go into the insulation which leads to the jack. So I'm confused about how I should go about it.

Build this http://web.telia.com/~u85920178/tx/bug5.htm

Then this http://web.telia.com/~u85920178/power/400mw01.htm

Finally this http://web.telia.com/~u85920178/antennas/vpole0.htm

Make sure you know at least basic electronics before you attempt this

Never build this http://web.telia.com/~u85920178/tx/bug5.htm

Then don't ever try this http://web.telia.com/~u85920178/power/400mw01.htm

Finally never this http://web.telia.com/~u85920178/antennas/vpole0.htm

Make sure you don't know the least of basic electronics before you attempt this

Thank you for your tips? :-)

GND = ground.

Then you fail at electronics AND common sense...

Honestly, I wanted to see how easy this was, so I went to wal-mart bought a FM transmitter for 10 bucks, took it apart found the wires labeled ANT (for antenna,jackass), proceeded to snip the wires, found old wire laying around, soldered it, and re assembled it. Keep in mind I have no background in electronics, have never taken an electronics class in my life. It's common sense. Total time it took?
10-15 minutes.

That is a neat transmitter. Will it do any frequency between 87.5 and 108, or just presets?

Anyways, what you need is a beefy linear amp and an antenna. A 100 watt amp should cover a large radius if you have the antenna high enough. A minimum of 10 miles. Maybe up to 100 miles if the conditions are right.
