COAX INFORMATION | CB Antennas
Coax Cable only needs to do two things:
First we want it, to take the received signal from the antenna towards the receiver. (in the best way it can without loss)
And secondly:
To bring the transmitte...

Single Loops | CB Antennas
The single “QUAD” element loop antenna.
The length of the wire is a full-wave.
Different shapes and ipedances with a single loop are possible :
We are going to make the 50 ohm variant, ” B”
Sizes are...

Radiations Patterns | CB Antennas
The radiation pattern of an isotropic in free space.
Free space is the world without “earth or other things” there is nothing for an antenna to radiate or “bounce” against. You can really look at it a...

3,60 DXbeam | CB Antennas
Front to rear versus frequency
The impedance is around 20 Ohms -j32.
A gamma-match is needed in order to achieve a good SWR.
