Sirio doesn t cut corners when it comes to the quality of their products.
Cb antenna attic ground plane radials.
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.
A ground plane for a cb radio antenna is the metal surface needed below the antenna.
4 3 out of 5 stars 14.
Any ground plane should have 1 4 wave 108 radials for the most effective ground plane.
Cb wilson firestik francis astatic cb radio antenna ground plane 3 8 x 24 black tip mirror trucker.
λ 4 and 5 8λ and questions like this often don t tell what s needed to answer the question.
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.
Nagoya gpk 01 21 radials nmo mount ground plane kit for base or.
Thus my questions in the comment above.
The cb base station antenna stands about 10ft.
In mobile applications the vehicle body frame 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.

Pro trucker white wilson firestik francis astatic cb radio antenna ground plane 3 8 x 24 mirror trucker by wilson.
The radiating element is a quarter wave λ 4 and the radials are 12 longer.
Tall when you finally install it which is high enough to capture more reliable signals.
Possibly the radials have been removed or the antenna has been otherwise modified.
In mobile applications the vehicle body acts as the ground plane reflective unit.
This calculator can be used to design a quarter wave ground plane antenna with radials.
Vertical antenna with ground plane radials.
Ahh the good old quarter wave ground plane.
Begingroup cb ground plane antennas come in various designs e g.
There are usually four radials three being a minimum but you could use up to six.
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 required below the antenna.
It is also possible to shorten them with marginal impact on the performance especially if they are loaded to keep their electrical length.
