Antenna sloper per 80/160 lunghr solo m. 17,50
Ho fatto una trappola per gli 80mt con del filo di 2 mm avvolgendo 40 spire su un diam. di 50 mm e spaziate 3 mm interponendo
un condensatore da 100Pf 10 kv. Fatti gli accordi per gli 80, ho aggiunto circa 12 mt di filo e ho fatto Fatti gli accordi per gli 80, ho aggiunto circa 12 mt di filo e ho fatto risuonare il tutto sui 160 mt

Portable Vertical Antenna for 75m & 40
Designing the Antenna for 3.8 MHz With a regular vertical: 62 ft. mast is required Too long Radial length 60 ft. Too long Use a telescopic mast, 27 ft.and a 3 wire umbrella on top Radial length 27 ft. Same as vertical radiator height
Loop antenna for Rx on 80m
I have been experimenting with loops and found them to be very good Rx antennas. They have a useful null and provide a wonderfull drop in noise to bring the DX
Vertical 80m balloon antenna
The antenna could not be simpler - 1/4 or 1/2 wavelength of thin copper wire I used 35 SWG enamalled copper wire. This amounts to 20 or 40m of wire
The Double Bazooka Dipole
The Double Bazooka Dipole is a very efficient single band antenna

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
