Antenna CB 27 MHz Links →
Half-Wave Dipole for 11 Meters
One of the easiest antennas to build is a traditional half-wave dipole
Moxon cb antenna for 27.200mhz
Construction PLAN view using aluminium tubing on Horizontal main boom and heavy copper wire
The best Antennas 27Mhz to my hand made
In the 1980 I started CB-hobby, then the antennas were half-wave, half, 5/8
Antenna EH for 27 MHz
E' molto semplice da costruire con parti di facile reperibilita', come tubi da impianti elettrici da 2,5cm di diametro ed un manicottio in ottone cromato per lavandini da 1 pollice cavo elettrico da elettricista

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
