Cb Antenna Attic Ground Plane Radials

Any ground plane should have 1 4 wave 108 radials for the most effective ground plane.

Cb antenna attic ground plane radials.

A ground plane for a cb radio antenna is the metal surface needed below the antenna. Cb wilson firestik francis astatic cb radio antenna ground plane 3 8 x 24 black tip mirror trucker. 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. The metal surface enables the signal generated when transmitting to reflect off the surface and travel into the atmosphere.

The radiating element is a quarter wave λ 4 and the radials are 12 longer. Ahh the good old quarter wave ground plane. The metal surface enables the signal generated when transmitting to reflect off the surface and travel into the atmosphere. This calculator can be used to design a quarter wave ground plane antenna with radials.

Nagoya gpk 01 21 radials nmo mount ground plane kit for base or. Begingroup cb ground plane antennas come in various designs e g. Thus my questions in the comment above. It is not always necessary to have a minimum of four radials often even two will suffice.

Endgroup mike waters jul 9 17 at 1 04. Tall when you finally install it which is high enough to capture more reliable signals. 4 3 out of 5 stars 14. The cb base station antenna stands about 10ft.

In mobile applications the vehicle body acts as the ground plane reflective unit. It is also possible to shorten them with marginal impact on the performance especially if they are loaded to keep their electrical length. The most common ground plane antenna to build is a simple 1 4 wave. λ 4 and 5 8λ and questions like this often don t tell what s needed to answer the question.

It also features 3 radials with plastic arms bracket reinforcement that further improve the transmission range. 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. 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.

A ground plane for a cb radio antenna is the metal surface required below the antenna. There are usually four radials three being a minimum but you could use up to six.
