3 Stacked Yagi Antennas
The use of three antennas often represents a good compromise between increased antenna gain, mechanical feasibility, and satisfactory handleability
432Mhz Quagi,
This Quagi is optimized for 432.2Mhz operation, however it works well in a quite wide range of frequency
5 Element-Yagi fur 145 MHz
Boom Length 1705 mm, Elements diameter 8-10 mm, hollow material they are obstructed by the boom, adjustment stub range length from the central arm to the collection clamp 175-200 mm diameter of aluminum tube from 6 mm distance between stub and radiator 15 mm
10 Element for 432 MHz Winkler Antennen
The elements have direct connection to the supporting boom by a metal ring where on either side one half of the element is screwed
70cm 10-element uhf yagi
Adjust lenght of the dipole if needed important,you can also use a folded dipole with a 1:4 balun

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
