Doppelquad antenna for 23CM
The Doppelquad is a well-tried antenna. New here is only the metallically grounded construction and the calculation for the 23cm band

Homebrew 23cm 12 element Yagi Antenna
I am using 18 mm square Western Red Cedar as the antenna boom. I am using Yagi Calculator, written by VK5DJ to generate the element lengths and spacings. At 1.2 GHz
Double quad antenna for 1296 MHz
This antenna is a medium gain directional antenna for mobile-portable and base station use
