Hi,
I'm playing around with some 433MHz transmitter and receiver pairs.
Ideally I would like the transmitter to transmit in a narrow
directional beam, but I'm new to the art of radio waves and antenna
design, so I was wondering if you guys would be able to help me with
my project. I've read about a Yagi design for the antenna, I know it
receives from one direction only, but does it transmit in just one
direction too?


As a general rule, the recieve and transmit patters of an antenna will be
the same. You may see some difference in propagation patterns due to
frequency differences between TX and RX pairs, but those should be very
minimal. The amount of difference will depend on the selectivity of the
antenna.

Simon.
