Begingroup cb ground plane antennas come in various designs e g.
Cb antenna attic ground plane radials.
Thus my questions in the comment above.
In mobile applications the vehicle body acts as the ground plane reflective unit.
The metal surface enables the signal generated when transmitting to reflect off the surface and travel into the atmosphere.
A ground plane for a cb radio antenna is the metal surface needed below the antenna.
Tall when you finally install it which is high enough to capture more reliable signals.
That consists of a single vertical 108 radiator section and 3 or 4 108 radials drooped at a 45 degree angle to provide the proper 50 ohm feedpoint impedance.
Any ground plane should have 1 4 wave 108 radials for the most effective ground plane.
Sirio doesn t cut corners when it comes to the quality of their products.

Vertical antenna with ground plane radials.
The most common ground plane antenna to build is a simple 1 4 wave.
This calculator can be used to design a quarter wave ground plane antenna with radials.
Pro trucker white wilson firestik francis astatic cb radio antenna ground plane 3 8 x 24 mirror trucker by wilson.
Possibly the radials have been removed or the antenna has been otherwise modified.
Nagoya gpk 01 21 radials nmo mount ground plane kit for base or.
Cb wilson firestik francis astatic cb radio antenna ground plane 3 8 x 24 black tip mirror trucker.
It is not always necessary to have a minimum of four radials often even two will suffice.
Ahh the good old quarter wave ground plane.
A ground plane for a cb radio antenna is the metal surface required below the antenna.
A common misconception is elevated radials as counterpoise perform the role of ground plane in an antenna system including dominating the far field effects from real ground over which the antenna resides.
λ 4 and 5 8λ and questions like this often don t tell what s needed to answer the question.
The cb base station antenna stands about 10ft.
The metal surface enables the signal generated when transmitting to reflect off the surface and travel into the atmosphere.
It also features 3 radials with plastic arms bracket reinforcement that further improve the transmission range.
