Antenna for UHF VHF Links

163



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

A 14 elements Yagi for 430 MHz
Gli elementi parassiti sono realizzati con tondo di alluminio da 5mm di diametro

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
