Considering the saturation level of most commercial FM stations, using a simple whip antenna will prove more than adequate. While a wide-range log-periodic antenna might prove useful as you get farther into your research, especially for broadband signals requiring a directional antenna, using simpler tools while learning is usually beneficial.

I'm afraid you did not make a mistake -- the LP0410 [1] is specified for usage between 400 and 1200 MHz. Whilst it will still pick up some signal at frequencies below 400MHz, operating it at a quarter of the lower cutoff freq. will lead to very suboptimal results.

If you know your frequency range as well as you do, I recommend trying Ralph's proposed 1/2 wavelength monopole antenna.

We're sorry. We made a mistake with the frequency range that the antenna could receive. It is actually 40MHz - 1.2GHz.
