The IBA-5 was primarily designed to be used from the inside of a building/structure, such as a CB'er who lives in an apartment or area that restricts the use of outdoor antennas. Other uses may include single family residences, offices, and job-sites. The IBA-5 may also be useful to hunters and campers (on the ground or roof of your RV) to establish a temporary communications center. This antenna is not meant to be a replacement for an outdoor base station antenna. In most cases the IBA-5 will not out-perform an externally mounted antenna so if you seek maximum performance, we recommend that you use an external antenna. This fast/easy complete assembly stands just over 5 feet (1.5m) tall. 'Bare-hands tunable tip' antenna (rated at 1000 watts). Partially pre-assembled base hub assembly. Four 30" (76cm) radials. 18' of RG-58A/U Fire-Flex coax cable. Complete assembly instructions are included. FireStik also includes a couple of extra tuning screws that can be used in situations. where SWR indicates insufficient ground plane.
