Corned Fed Delta Loop
The Delta Loop antenna is one of the famous magical antennas, but in reality, the Delta Loop antenna is not as magical as it's reputation. Despite its reputation as a Multi

2 Elements 20m Delta Loop
For this project I started from a Nerio Neri Book antenne.The book describes the building of a HF three bands 10-15-20 aluminium delta loop, but I limited the design to 20m band only
2 element 40 mt parasitic switchable array
He used 3/8 electrical wavelength feedlines to each element. He would transmit with a single sloper the other ones acted as reflectors. Why? Because the 3/8 wavelength feedline going to the other slopers

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
