Antenna for UHF VHF Links →
70cm-Longyagis in 28Ohm
The elements have 10 mm, 8 mm or 6 mm diameter, because this is very uncritical and you get the expected datas! For the tuning let the radiator 2mm longer and cut for best SWR at 432 MHz
900 MHZ Quagi beam
The quad elements were made from #11 AWG copper rewind wire and the directors were made from .063 diameter brass welding rod
Yagi for 432 MHz
Frequency of 432 mhz,9 director elements, for a total of 11 elements
A 2-Meter Phased-Array Antenna
a small vertical phased array that can easily be built and cost is minimal is taken from an article in QST
Antena Doble Bazooka para 2 metros
Antenna built with coaxial cable, measures from the formula 158.9 / F, total length, 99.6 / F length of the coaxial cable
