Answer 1

hi, sorry for my english.

for your 1 w fm transmitter to cover 3 to 4 km range.

1. choose a free and no noise frequency on your area Try (88.0 to 88.9mhz) exp.

2. make a dipole antenna correct measure for your frequency.

3. install your transmitter in water proof box and put it & the antenna on roof outside

and your coaxial cable 1 foot max between the box and the antenna, you need from your room to the transmitter music signal and power cables.

4. ( optinal and not recommended ) if your transmitter take 6vdc to give you 1w connect it to 9vdc to give you 1.3w ( you have to protect your transistor output power & biger heat sink) .
