I have no idea what a "FCP" is, but it doesn't matter.
1. An inverted L is an _unbalanced_ antenna. Therefore you don't
need a balun.
2. This means you can feed it with unbalanced line, i.e. coax.
3. You can use an unbalanced matching network such as an L network,
preferably at the feedpoint.
4. Make the total length of the driven element around 140 feet and
put down enough radials, 60 to 100 is good, and you have no problems
with common mode RF on the feedline. The returning current to the
feedpoint is distributed over enough conductors so that what's on the
feedline is minuscule. If you have to fool around with ferrite cores
and such then you don't have enough radials down.
