you can use old vacuum tube( valve) some thing named so, this can be found in an old TV or radio. nowadays we use the Transistor instead .
those valves are very useful for long-distance FM transmission .

Well you're not gonna make it happen with a modded iTrip. You'd need to get a serious transmitter and build it yourself like at freeradio.org. Not cheap, but not super expensive.

Not to mention that in a lot of places building a transmitter with that range without a licence would be illegal.

Because companies pay a lot of money to government(s) for the right to broadcast on FM frequencies. There are laws that govern the strength of a transmitter you're allowed to use as well as frequencies allocated for hobby use (AM frequencies).

Look at Ramsey Electronics.  They have some nice FM kits and prebuilt stuff that works.

I don't know about 5 miles cause that's gonna get you busted real quick, and sometime a pretty big fine even for first offenders.
