The two tried-and-true methods are 1) a LOT of gain, meaning BIG antennas, or 2) switchable circular polarity.  In the latter case, even small antennas with a preamp work quite well.

Most people using Arrow Antennas (or equal) manage pretty good reception using the twist-and-turn method.  I use a little 3-element Yagi and can typically copy 90% or better of the pass.
