Question by mlee404: Ham/CB/FM radio broadcast antenna question?
Could you cut or lenghten a 2 meter ham (144 to 148 Mhz) broadcast antenna to make it broadcast FM (88 to 108 Mhz)?
If so is there an equation for this?

If it is a whip antenna then you can increase its length so that its resonant frequency falls within the f.m. broadcast band.

(Amateur bands are not referred to as “broadcast.”)

You can find antenna design information on the net.

However, if your antenna has a loading coil the extra length will have to be determined by trial and error.
