Building 2 element Yagi from Ampro is ridiculous idea imo.
You need 4x Ampro, it means that for 20m beam you need to spend 480PLN just for antennas. You need 3/8 mounts, boom etc. so more money to waste.
Instead of that Yagi substitute you can have http://www.qsl.net/dk7zb/portabel/2-element-28ohm.htm which can be build for much less money, better performance and multiband operation. Portable as well.

You can't have too many antennas...
