11 Meter long wire27 mhz antenna
Radiator 215 cm frequency 27.205 MHZ
Dipolo rigido per 10 ed 11 mt
To be used for some outings in the mountains and therefore not bulky and easily transportable, the choice fell on a rigid dipole easy to make
Antena plano de tierra
The measurements of the antenna of the drawing are practical, the whip measures 2.75 mts the complete tube, with everything what goes into the insulation. And the four radials of 2.61m each
Introduction to SWR Testing of CB Antennas
SWR (measured with an SWR meter) shows you how well your coax, antenna mount, ground plane and antenna match the output capability of your CB radio

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
