24 Mhz 3 element Yagi Antenna
This is a high-gain, wideband LFA Loop Fed Array Yagi which covers 24.890 - 24.980MHz with an SWR of less than1.1:1

2 element yagi per 24 Mhz a carico lineare
misure sui 24 Mhz, la formula e' sempre la stessa, con l'unica nota che bisogna tenere presente l'accorciamento che bisogna dare all'elemento per il carico lineare

28 and 24 MHz Limited Space 3/4 Wave Delta Loop
Here is a simple and easy to build antenna in a Delta Loop configeration that should make 10 and 12 meters

4 element yagi for 24MHz
This is a high-gain wideband Loop Fed Array Yagi which covers 24.890 MHz

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

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
