2M15S-B Firestik 2 Meter 1/4 Wave Tunable Tip 17 Antenna with Spring in Black 135-168 MHZ 100 Watt 3/8x24 Thread
The "2M15" series, 2 meter amateur antennas are little quarter wave wonders. Made of top quality materials, Firestik's proven antenna knowledge and their tunable tip design, Firestik built a pair of dependable antennas you can count on for your day to day communications.
The 2M15S-B is 100% American made with 100% American materials. The core material is solid 3/8" (9.5cm) fiber-rich, custom blended, fiberglass. Each is hand wound with double insulated 19 gauge copper wire. The 3/8"-24 threaded base will fit all common mounts and accessories. Both antennas are covered with a static reducing, water-tight sleeve containing UV and pigment stabilizers. A vinyl cap is provided to protect the tuning mechanism from the elements.
Like most transmitting antennas, these antennas work best when mounted over sufficient ground plane. The versitility of the tuning screw design offers a wide tuning range. The lowest frequency is achieved by having the tuning screw in its highest lockable position and the vinyl cap installed. Likewise, the highest frequency of the antenna can be found with both the vinyl cap and tuning mechanism removed.
The 2M15-B should be selected when the user has no need for the added protection from a spring.
