For many years amateur radio operators have raved about Firestik 2-meter mobile antennas (Model 2M-4) because of its outstanding performance. One user was so elated with the performance of the mobile whip that they pieced together a base antenna that used the mobile whip as its radiating element. The end result of their "experiment" was discovering that the base antenna performed even better than the mobile antenna. Their enthusiasm was so great that they asked us to consider making a commercial version for them to sell. And so, opportunity knocked, and we answered the door.
The radiating element is a 6dBi 5/8 wave design. The core material is 3/8" (9.5mm) solid fiberglass that is wound with 19 gauge heavy insulated copper wire. The radiating element is approximately 45" long (114cm). All of this is covered with white, UV stabilized PVC shrink tubing. The antenna base threads are 3/8"-24.
A combination angle bracket, u-bolt, hub plate and antenna stud is central to the assembly of the base antenna. This assembly will mount to the top of any mast up to 1.5" (38mm) in diameter. The kit comes with four (4) structural aluminum (6061) radials that measure 1/8"x1/2"x20" (3mm x 13mm x 51cm). Each is pre-drilled to mount to the hub plate. The antenna stud utilizes a standard SO-239 base for easy hook-up with any UHF (PL-259) terminated coaxial cable.
The top to bottom height of the entire assembly is a mere 49" (124cm) and the diameter of the radial circle is 44" (112cm). All mounting and assembly hardware is included.

Firestik 2MCKB Review By: Budhi P.
- No adjustment available to tune SWR. Out of the box, the SWR was 2:1 mounted on the tower 50 feet of the ground with RG8U Coax. Will do experiment by cutting the element 1/8 inch shorter to bring down the SWR. If it needs to be longer, then this antenna will go bye bye.
