The MSB-RX antenna is for use as a home base scanner antenna.  The primary element is an efficient, wire-wound design with special built-in traps for better performance in the action-packed 140-170 MHz band.  However, the antenna can be used to receive scanner signals between 25 and 1200 MHz.  The primary element is 3 foot (91cm) and white in color.  The kit also includes a complete mounting assembly, and three 24 inch (61cm) solid aluminum radials.  This base antenna assembles and mounts in a matter of minutes.  It can be mounted to a mast, a vertical or horizontal rail, or to the side of any building or structure.  The antenna termination is a standard SO-239 so you may use any coax cable that is terminated with a standard PL-259.  Due to the various locations that users install the antenna, we do not supply the coaxial feed line with this kit.  Nonetheless, the antenna requires RG-58 or equivalent coax for the feed line from the antenna to the scanner.  Firestik offers a 50ft (15.2m) RG-58A/U coaxial cable that is terminated on one end with a weather-tight PL-259 connector that will attach to the MSB-RX antenna.  The scanner end is not processed due to the variety of possible connections used on scanners (RCA, BNC, UHF, etc).
