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
Embedded GSM antenna
Embedded GSM antennas Lambda/4 the red coloured part of the picture view is the part of antenna that will radiate at the lower band GSM 850/ 900MHz. A+B+C+D = 79 mm
Easy antenna dual band VHF-UHF
Questa antenna, concepita con l'aiuto di Yagi-Calculator, un piccolo programma molto pratico

Linear loaded short dipole 21Mhz For my amateur radio activities on the HF bands I only have a 3.6 m wide balcony available for antennas. After some study I decided to experiment with a shortened dipole for the 15 m band
Rx antennas 4Square Rx Vertical Array My frequency design of 1.825 MHz a 90 degrees line would be 33,70 metersinstead of the previously calculated 33,27 m
Atu balanced feeder antenna system An ATU has the advantage of bringing the feeder-antenna system to resonance, act as a band pass filter both on receive and transmit and a low SWR
