Antenna for UHF VHF Links →
Triband Yagi for 6 m, 4 m and 2 m
Developed with the software EZNEC +5 and has only one feeding point of 50 Ω and a boomlength of 1,25 m
2M 144MHz yagis
Follow the instructions carefully to avoid making mistakes
VHF antenna construction
In making a folded dipole element I used a tube bender, apparently the bending jobs must be done once without failure
Vhf magnetic loop
A magnetic loop has very small bandwidth butunsensitive to man made noise
VHF/UHF Wideband Portable Dipole for the FT-817
A dipole has about 3dB gain over a quartre wave antenna, is why my preference went to a simple dipole
