Hello! Are you interested in a beam that takes little space and the weight is just over 1 kilo? Check out my bamboo beam for 21 MHz which I constructed and tested during this very nice summer. You can find it at:

Click on "Buttler" at lower left side of my site and you will get a zip-file in english! Have fun! / SM0DTK / Martin
