Improving Signal of FM Transmitter

I recently bought the C. Crane FM transmitter. I have not had much luck with it even after turning up the pot as described on the internet. However, I am not giving up yet. Below are some possible things that I have thought of to improve the sound quality of the radio at a distance from the transmitter. 1. run wire from the antenna of the FM transmitter to the ductwork in my house. I already tried this. I had better luck attaching the wire to the exterior of the ductwork in my basement rather than the interior of the ductwork. 2. create some sort of repeater(s) to get around walls. This device would have to be a receiver/transmitter. 3. create my own FM transmitter with the best parts that I can find. 4. Use a homeplug system. Your suggestions are much appreciated. I don't know a darn thing about electronics so if you have any recommendations for good books that would be nice.

Build a broadcast antenna exactly the width of the broadcasted bandwidth or an exact devisor thereof (1/2, 1/3. 1/4, etc.).
