7 Watt FM Transmitter Range Test

I got this 7 Watt transmitter and connected a dipole antenna to it. Put it up in my office inside the house. Got INSANE distance out of it. Way too much for my own personal use. Its actually sort of funny since my intention was to get a FM transmitter for around my house so I could listen to my tunes at home on any FM radio. Now the whole town can hear it.I have sold this transmitter and no longer have it.
