Firestik Antenna Company 2M-CKB 5/8 Wave 2M Base Vertical Antennas feature a 5/8 wavelength radiating element and boasts 6 dBi gain. The core is made of 3/8 in. (9.5 mm) solid fiberglass, wound with 19-gauge heavy insulated copper wire. The radiating element is approximately 45 inches (114 cm) long and is covered with white, UV-stabilized PVC shrink tubing. The antenna base threads are 3/8-24 in.

Central to the assembly of this base antenna is a combination angle bracket, U-bolt, hub plate, and antenna stud. This assembly can be mounted on any mast up to 1.5 inches (38 mm) in diameter (not included). The kit includes four structural aluminum (6061) radials, each measuring 1/8 x 1/2 x 20 inches (3 mm x 13 mm x 51 cm), pre-drilled for easy mounting to the hub plate. The antenna stud uses a standard SO-239 base for easy connection with any PL-259 terminated coaxial cable.

The hub plate is a unique design that brings this base antenna together as a commercial kit, offering numerous creative opportunities for hobbyists. The total height of the assembly is 49 inches (124 cm), and the diameter of the radial circle is 44 inches (112 cm). All necessary mounting and assembly hardware is included.
