Poor FM Reception

PS - I am not an expert but I think it's the INVERTER in a solar power set up that causes the RFI, not the panels themselves. 

@erik_squires Thanks picking up my poor wording.  Appreciated.  A solar system generates RFI at the inverter, not the panel.   Instead of system I typed panels in error.  That’s why I stated to install the outdoor antenna as far away from the inverter as possible.  A solar system wiring carries current.  Any wire carrying current generates RF.   Installing ferrites on the wiring, which absorb high frequency radiation including RFI) and dissipates it as heat, is a simple way to reduce RF substantially.  Thanks again and apologies to all on my unclear wording.  

Solar does not carry RF it is 240 volts AC.

Received FM Twin Lead antenna. Went from 2 FM stations using the Terk antenna to 8 FM stations. Some have minor but annoying background noise. Should receive 15dB amp tomorrow and hopefully resolves the noise.

Received Tru-SpedcTMA-15 and Radio Shack 15-1122 RF preamps. Found out both amps are same build. Neither made much difference in reception. The True-Spec was slighter better. The amp did remove the slight noise on some stations but not all. I will keep the amp. Figure if the signal is weaker on the antenna the RF amp does not have much to amplify.
