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

Antenna for UHF VHF Links →
Hb9cv Antennen fur 2m,6m,10mt
When compared to two-element antennas of conventional design, it can be assumed that the HB9CV gain of approximately 4.2 dBd 1 is about the same as that of classic beam / reflector and radiator / director combinations
Hen antenna per i 144 mhz
La Hentenna rientra tra le antenne Loop, come classificazione, ma come funzionamento e un mondo ase' stante
HF-NVIS and VHF Antenna System
This describes a portable antenna system that can provide both fifty mile range on 2 meters and 300 mile NVIS HF coverage on the 40M and 75M bands
Lightweight 4 Element Yagi for 144.3MHz
Antenna up at 1.4mm stainless steel rods and 11mm PE installation tubing as used by electricians

23cm Yagi Antenna building Finished antenna at 1275 MHz SWR under 1:1.5 at resonant frequency
50 MHz preamp Gain 26dB with the BFG135 Preamps for 144 and 430 MHz, for 50 MHz, the BFG135a is a cheap transistor and in my view rather strong. It is not easily damaged by static discharge or RF power. FG connection
Interface-for-digital-broadcasts-with-integrated-audio 4-port HUB, with a TUSB2046. With port 1 of the HUB we drive the FT232RL; with port 2 the PCM2904, furthermore, we decided to leave ports 3 and 4 free
