Double Twin Quad Antenna Project for 70cm
The Double Twin Quad Antenna for the two-meter band we were very surprised, if not deeply impressed, by its apparent performance

Dual band colinial 144-430
97 cm RG8U stretch VHF, 32 cm RG8U stretch UHF, 16 cm stretch RG8U UHF

Gamma match
The layot of the gamma-match,mnusthe capacitor, is one-half of a T

Gsm antenna 937.8 MHz
The Driven Element is a dipole which consists of two 1/4 wavelength elements. The Reflector is slightly bigger then the driven element and reflects the signal back towards the driven element

Easy antenna dual band VHF-UHF
Questa antenna, concepita con l'aiuto di Yagi-Calculator, un piccolo programma molto pratico
