MURS16-B - Firestik 16" MURS 1/4 Wave Mobile Antenna This quarter-wave antenna is designed for the 151 to 154 MHz multi-use radio service band. This antenna uses the same high quality materials and proven antenna knowledge Firestik uses for all their antennas. It also has the same bare-hands tuneable tip that the Firestik FS series CB antenna have. At just over 15" tall (without spring) and 1/2" at it's widest point, this antenna is low profile. It is compatible with any Firesik mounts or accessories or other brands that are threaded 3/8" x 24. Frequencies The MURS16 is designed for use on 151 to 154 MHz With an adequate ground plane, it will operate in this range with a 1.5:1 or better SWR. Testing has shown this antenna will operate in the 138.200 to 171.720 MHz range with an SWR of 2.0:1 or better. Construction The MURS16 is constructed in America from high quality American parts. The core is a solid 3/8" fiberglass rod. It is hand wound with 19 gauge copper wire and mounted on a 3/8" x 24 threaded base. The optional spring is also American made stainless steel. Spring If you are going to use this antenna with a spring, it needs to be purchased with that option. See the MURS16S-B. The antenna length is modified for the spring. If you attempt to use the MURS16-B with a spring rather than going with the one with the optional spring, the MURS16S-B, the SWR will be extremely high.
