Wideband VHF/UHF/SHF 22dB PREAMP by MAR-6

The best place to put a pre-amplifier is with out a doubt as closest to the antenna as possible. If possible, directly mounted at the feeder (dipole) and using phantom-type powering of the amplifier. The RF/DC splitter comes inside the shack just before your receiver. Keep the connections as short as possible @ RF IN and RF OUT and keep them in 50 Ohms impedance starting at the leads from the IC. Mount it in a shielded casing.
