160/80m Coaxial Loop Receiving Antennas
Over the past several years I've been asked one question. Are you still building the receive loop antennas it is hard to believe twenty years have gone by, but to answer the question. yes, I am still building 160/80m, 80m and 160m receive loops

160m End Fed Antenna
The antenna is sported by a 22ft 6.7m central support and a 12ft 3.66 end support
Loaded Dipole for 160 Meter
Total Length 26 m 85 ft. Total Weight: 380 g Mesh constructed with enamelled wire 0.5 mm diameter Mesh-size 4 m x 2 m 13 x 6.5 ft
Morgain 160mt
The total length of each of the radiator halves is about 60 m. They are folded three times, as shown schematically

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
