Tuning and matching an antenna to a receiver or transmitter is not simply a matter of adding inductance.
You need to have measurements of the antenna's characteristics and to know the value of impedance to which it must be matched.
A working knowledge of the Smith chart would be useful too.
Pancakes is confused. A resonant antenna, correctly matched to the input of a receiver, will give better results than an untuned and/or unmatched antenna.

I assume you're trying to filter out ham interference or something like that. You can buy an fm tap from Radio Shack. I don't know what's inside them, but I have used them. They look like a typical television splitter, one coax in, two coax's out. On this one, one of the outs is television and one is FM. Like I say, I haven't taken one apart and don't know how they are constructed, but they're not too expensive. May be worth a try.

88-108 is commercial broadcast. Why would you need a coil on your antenna? Unless you're broadcasting on it, (hope you have a license) a tuner will make no difference in reception.

Check on Ebay. You might find a better buy than at any regular store.
As far as making one cheaper. If you have all the right components and directions for putting it together, it might be cheaper in the long run.

Any radio shack. If they are out, they can have one in the next day.
