PRODUCT DESCRIPTION
LBA Technology’s CAMI® series of new-concept low, medium, and high power broadband isolators are the modern way to mount additional antennas on “hot” AM towers. These broadband colocation systems offer a simple, economical solution to take full advantage of existing vertical real estate. The LBA CAMI® isocoupler family supports any combination of RF carriers from DC to 2700 MHz or more, and conservative RF power levels to 40,000 watts at FM.
New! The CAMI®CAT enables two CAT6 POE Ethernet cables, to colocate on AM towers.
High Impedance AM isolation is achieved on any specified frequency between 530 - 1710 kHz. Your CAMI® provides a simple, cost effective way to mount antennas and their coaxial lines on existing directional or nondirectional AM towers without significant changes to the transmitting system. Standard CAMI’s handle low to medium AM power. Custom AM multi-frequency and high power systems are also available for special applications.
CAMI® systems are specifically designed to isolate multiple CAT6 cables and single coaxial cable feeds for WISP broadband, two-way, microwave and STL links, FM translators, low power FM, LPTV and television translators- even for high power FM & TV colocations. Unlike commonly used tuned isocouplers, the same broadband CAMI® model will fit all of these application frequencies without retuning.
Since CAMI’s are very broadband, an FM or TV operator need not change isocouplers, even if they are reallocated. This is important with the current unsettled state of low power and translator allocations. And, with FCC approval of translators for AM daytime stations, your CAMI® provides a simple, cost effective way to take advantage of an “AM” translator by mounting your translator antenna on your existing tower. The CAMI® CAT opens thousands of AM towers for broadband data services.
CAMI’s also have the advantage of passing AC or DC current to tower top amplifiers and are resistant to weather and lightning. LBA isocouplers are budget-friendly and easy to install from ground level with supplied hardware.
TRULY THE STATE-OF-THE-ART, BACKED BY OVER 40 YEARS OF COLOCATION EXPERIENCE
