Antenna for UHF VHF Links →
2 x 5 Element Yagi array for 144MHz
A 2 x 5 antenna may have similar basic gain to say a well made 10 element long yagi but with slightly different distribution of azimuth and altitude
A Halo 4 Stack for 70cm on the Cheap
Start by cutting a piece of copper tubing per the dimensions in the diagram above
A Yagi-Uda antenna for MURS and 2-meters
The yagi that I built was designed for the lower 3 MURS channels but was also to be usable on 2-meters
hentenna for 2 meters
hentenna for vhf 2 meters

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
