4 element 14 mhz yagi for 7 MHz
This article is about how to turn a CueDee 4-element monobander for 14 MHz into an efficient duo band for 7 and 14 MHz with some ingenious handles.
2 elementi Yagi per la banda 40
Mi son deciso di scrivere delle note tecniche e costruttive della 2 elementi Yagi per la banda 40 metri home made OB2-40
Linear Loaded 40m Dipole
Here is my dipole for 40m band. It is a simple linear loaded dipole feeded with 450-Ohm openwire feedline
40 meter Phased Array
Coaxial delay lines in his two-element phased array, and some users still use delay lines with good results

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
