146MHz 5/8 Ground plane antenna
The reason for selecting the 5/8 wave ground plane is that for a simple single element antenna

Antenna for UHF VHF Links →
Two Versions of stacked
The picture left shows shows the 4x5-Element-25-Ohm-Yagis with 2-m-boom and a stacking distance of 2,30 m. Two Yagis are connected together with Aircell-5 transformations lines
Yagi homemade for 2m
Here I would like to show how you can build a good Yagiantenne yourself relatively easily and cheaply
Yagi 6 elementi 144MHz portatile
L'antenna dovra' ovviamente essere leggera, facilmente montabile e smontabile
Yagi 6 elementi per i 144 - 145 MHz
La costruzione mi ha portato via alcune sere, lavorando un'ora o due per sera
Yagi vhf 9 element
All element are connect to the directly NOT isolated from the boom
149

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
