Antenna CB 27 MHz Links →
11 Meter long wire27 mhz antenna, NL3ASD
Length may also not be correlated to the desired wavelength but adapted for convenience
11 meter Moxon Antenna suitable for 27MHz CB
The Moxon antenna has proven popular because of the ease of construction and low cost, but still yields exceptional HF DX results at low
11 meter j pole end fed antenna
Half wave end fed antenna for 11 meters. Can be hung vertically or horizontal. Horizontal is good
27 MHZ 1/2 Wave Dipole
After you have it installed and if you find that the s.w.r. is a little high you can lower it and trim off some wire from the ends of the dipole
4 element yagi for 27 MHz
To model it, I used the excellent YagiMax 3.0 version, which can be downloaded from the download section.

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
