I got these calculations for yagi while SEARCHING.ĭriven length = 30.27 cm at 12.77 cm from reflector (at 12.77 cm)ġst director length = 28.76 at 12.77 cm from driven el. Im all for soldering and everything just need to know the length of the square elements. If you can get me that great, otherwise im going for a yagi for FIRST antenna. I found calculators for yagis, but not calculators to give me the square driven element or reflector. Well the only reason i said the quagi was to complicated is because i found no calculator while further searching.
