Product Details
FS-II No-Ground Plane 4' White CB Antenna Kit (FG4648W) by FireStik®. "No ground plane" CB antenna kit were specifically designed to solve the problems associated with the lack of ground plane (counterpoise). This normally occurs on vehicles constructed of plastic, fiberglass, wood or aluminum. This includes, but is not limited to, motorhomes, boats, automobiles and 18-wheeler trucks. Ground plane problems typically show up in the form of high standing wave ratio and poor performance. The isolated ground plane that is built into the FGX-648 series kits can also eliminate problems on metal base vehicles that lack the sufficient ground plane for proper operation. This could be due to the size of available ground plane (ATV, bicycle, motorcycle, wheelchair, etc.), or because the operator chooses to mount the antenna in a location that is unable too properly take advantage of available ground plane.
Notes
- ALL antennas, regardless of style or manufacturer, must be tuned after installation on the vehicle. Transmitting antennas are not "plug-n-play" devices.

The versatility of these kits goes way beyond the normal expected uses of a typical mobile antenna kit. Aside from vehicular installations, these kits can be mounted on a pack frame for hunting or Search and Rescue operations. Apartment dwellers can mount them on a balcony railing, or a temporary base station can set up in the forest using a tree for a tower.
ANTENNA: The antennas used in these kits utilize the same 5/8 wave design as the patented Firestik II tunable tip antennas. The antenna's frequency is altered in order to maintain a desirable center band position when used with the tuned coaxial feedline. Accordingly, these antennas may only be used with the Firestik NGP cable. The core material is a 3/8-inch (0.375" or 10 mm) diameter reinforced plastic (fiberglass). Custom blended formula offers a preferred balance of flexibility and strength. The chrome plated machine brass mounting base has standard 3/8"-24 threads. A high efficiency, voltage increasing helical wind is utilized. Heavy insulated copper wire is used to guard against shorted coils and corrosion induced resistance commonly found on non-Firestik brand antennas. The antenna used in these kits have patented "no tools required" tunable tip for fast and easy SWR adjustments. The rated wattage for these kits is 100 watts. Each antenna is covered with a static reducing, heavy PVC shrink tubing with both pigment and UV stabilizers mixed in.
COAXIAL FEEDLINE: The seventeen' (5.2 m) coaxial cable used in these kits is of the highest quality. As a matter of fact. NGP cable assembly utilizes a custom manufactured coaxial cable that can only be found at Firestik. Unable to find the performance characteristics in any of the commercially available coaxial cable. designed own. First use a multi-wire stranded center conductor to the prevent breakage that can occur with solid center conductor cable. A condition known as "cold working" occurs where vibration is present and this action can cause solid conductors to become brittle and eventually break. Surrounding the center conductor is a long life, flexible, polyethelene insulation. Since shielding is extremely critical on NGP systems, used a double shield around the center conductor. First, a 100% aluminum tape covers the center conductor insulator and then a copper wire braid (averages 95% coverage versus the industry standard of 70%) is applied over the aluminum tape. The coaxial feedline, besides being the conduit for the signal to reach the antenna, serves as a tuned circuit that creates the necessary counterpoise. If a longer cable length is required, the user may add standard RG-58 A/U cable between the radio and system cable, preferably in lengths that are multiples of nine feet. Because it is a tuned circuit, the length cannot be reduced without causing non-repairable damage. Should the cable become damaged, order replacement cable model K-8NGP.
MOUNT, SPRING AND HARDWARE: To compliment the quality of the antenna and feedline, the mount used in these kits is stainless steel, 3-way 90° angle mount. Mounting options are, 1) any vertical bar, rail or post, or 2) any horizontal bar, rail or post, and 3) any flat vertical surface such as the side of the vehicle.
FireStik® is located in Phoenix, Arizona, USA. Since its formation in 1962, the company has remained focused on the personal communications market. At various times during its existence, FireStik has manufactured CB radios, test meters, amplifiers, RF filters, and more. In 1975, the company directed all energy into designing a line of high-performance antennas. Now FireStik offers an extensive selection of antennas and accessories for the mobile CB market. The company is especially recognized for its high-performance wire-wound CB antennas that have gained worldwide fame. Aside from specializing in CB antennas and accessories, FireStik's years of antenna know-how can be also found in antennas made for scanners, two and ten meter amateur equipment, and specialty antennas such as those used for geoseismic exploration.
