Antenna CB 27 MHz Links →
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
Double wire 27mhz Doublet
The values indicated are calculated for 27 MHz, the popular and authorized frequency

Take off angle of horizontal antenna For horizontal polarization, the electric field will move sideways on a horizontal plane, while for vertical polarization it will oscillate up and down on a vertical plane
Rx antennas 4Square Rx Vertical Array My frequency design of 1.825 MHz a 90 degrees line would be 33,70 metersinstead of the previously calculated 33,27 m
Atu balanced feeder antenna system An ATU has the advantage of bringing the feeder-antenna system to resonance, act as a band pass filter both on receive and transmit and a low SWR
