hi kevin,

Since you're interested in a 2 element yagi for reception only,
how about a Moxon antenna ?

You can use aluminum rod and pvc, takes up less space
then the Yagi but almost same performance.
Or try it with the tape measure for elements.
Direct fed with 50 ohm coax.

Here is a calculator to help build a Moxon for a given frequency.

Good luck!
