A Stealthy HF Coat Hanger Antenna
No this is not about some cute antenna that's about the size of an oatmeal box and runs at 100% efficiency from 160 all the way up to 10

Antenna EH per 160 metri,diametro tubo 400mm materiale del tubo PVC
Getting on 160 Meters
It's true, a full sized, half wave dipole for 160 meters is rather big around 250 feet long
Inverted-L for 80m & 160m
On 160m good performances, I could only test this in SSB, despite the fact that topband is a CW band! Noise level S7 about BW 2,2 kHz. Worked several stations in USA and S. America Brazil, Nicaragua with 800w PEP. Bandwidth for SWR 1.5:1 is 20 kHz, for 2:1 30 kHz, for 3:1 is 50 kHz
Lifted antennas kite for amateur Radio 160 Meters
The foul weather vertical is working against about a kilometre of wire under the ground. Radials, about 60 of them, vary in length from 45 to 120 feet

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
