    433 MHz Coil loaded antenna

    Yes I completely agree. I have been testing the 433MHz TX/RX arrangement and have concluded that the RX that comes with those very cheap TX/RX pair is completely useless for anything above a few metres.For use with anything realistic, for example a sensor outside and the receiver inside via a few walls then either an Aurel receiver or as you mention the RXB8 gives good results with just a quarter wave antenna (168-170mm). However there is indeed a marked improvement with the antenna you describe.
