Default Transmitting SW antenna question - pls help

What frequency do you suggest testing my equipment at? The antenna I
believe goes from 131 to 512 mhz. The allocation chart shows nearly
every frequency in that range in use for something. Would 140 mhz be
ok?

Also, I'm not really sure how far the signal is going. Using the line
of sight formula with how small the antenna is, I can't really see the
signal going beyond the remote area where I live (which is not close to
any airport). To test it I'd pretty much have to broadcast on an FM
station, get in my car, and drive until the signal isn't picked up, but
this too can be a risky venture.

I hope you are not transmitting on 121 MHz area. That is part of the
108 to 136 MHz aircraft band if I am not mistaken. 121.5 for instance
is an emergency frequency and it is monitored.

This chart may be helpful to avoid causing interference on sensitive
frequencies.
