Product Details
MURS Mobile 45" Black 5/8 Wave Antenna by FireStik®. The Non-License Vhf Citizen Band Service. The Firestik™ MURS45 antenna is an omni-directional antenna for the 151.820 to 154.600 MHz, VHF Citizen Band Radio service. The Firestik™ design offers an exceptional low angle of radiation for optimum ground wave propagation of your transmitted communications. This 5/8 wave (physical & electrical) antenna has a nominal impedance of 50-52 ohms. With a sub 2.0:1 swr bandwidth of 6 MHz (3 MHz sub 1.5:1) the MURS45 exceeds the 2.78 MHz bandwidth of the MURS band. The overall length is 45" (114 cm). Gain over isotropic is 6 dB. Gain over 1/4 wave is 3 dB. The MURS45 antenna is rated at 400 AM watts (800 P.E.P.) thus exceeding the initial authorized 2-watt transmitter output by a factor of 200. The core is 3/8" (0.375" or 10 mm) solid fiberglass (special Firestik™ formula for balance of ruggedness and flexibility).
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 conductor is that of double insulated 19 guage copper wire. The static noise resistive covering is made of high quality PVC with added UV and pigment stabilizers. The antenna base is chrome plated machine brass with standard 3/8"-24 threads for full compatibility with all Firestik™ mounts and accessories.
These are ground-plane dependent antennas. They require a metallic counterpoise to perform properly. They are not suited for use on non-metallic (composite) vehicles or those with insufficient metal. They can be used with a transmitter (versus a receiver) these antennas should be tested and tuned across the radios operating frequency. Using an untested, untuned antenna for transmitting can damage the transmitter circuitry. Ground-plane dependent antennas require mounting brackets and antenna stud mounts that are grounded to a chassis ground point. Powder coating, paint and/or anodized surfaces are insulated coatings and must be removed down to the metal surface where ever a grounding point is required.
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.
