Easy antenna dual band VHF-UHF

My disign is a dual-band j-pole, if you own a 2 meter/70-cm H-T thisantenna will improve your signal on both bands

Antenna for UHF VHF Links

150



Cheap Yagis 144 MHz.antenna
The simplified feed uses the structure of the antenna itself for impedance matching. So the design started with the feed and the elements were built around it

Coaxial Colinear For 432 MHz
the collinear antenna has been around a long popularity, make a collinear antenna from coaxial cable simple

Coaxial Dipole
The Folded Dipole exhibits the self-balancing behavior. The feed impedance is several times higher than the cylindrical dipole's

Cubical quad 8 elements 144MHz
The 2.5m boom is a 20x35mm rectangular tube that is easily found in DIY store the distance between the reflector and the last director is 2.47m

Delta Loop for 144mhz
