Building a 440mhz quagi antenna
The Quagi requires neither fine tuning nor careful handling

Regarding the polarization of this antenna, what is said for the Turnstile is valid, since the circular polarization is obtained in the same way,the impedance adaptation is also similar

Lowcost yagi antenna for PMR446, easy to build
PMR446 stands for Personal Mobile Radio and is a license free radio in the 446 MHz UHF band. That is about 6 Mhz above the 70cm amateur radio band
