I made one for 137mHz to decode the NOAA WX says. Easier than it looks. Cost was about $25. I found an online applet that calculates the dimensions and prints a drilling template
 If your intersted,let me know and I'll dig up the url. (Bookmarked on another computer)

out how to get those M2 yagis up in the air, really.
