The loss will be considerable. Yagis are quite narrow band. For a few
bucks/pounds/euros you can buy some aluminium tubing from a hardware store
and build your own.

Or look for "broomstick and wire hanger" designs on the web. If you
have a long enough piece of wood for the boom and a few wire hangers
it'll cost you nothing and still work as well. Or you might look into
building a quad - more gain with less antenna.
