CoLoCoil - LBA Group, Inc
Multiple antennas and future add-ons are no problem for the CoLoCoil AM isocoupler. Even with different coax cable size requirements!LBA's modular approach allows the operator to start with one CoLoCoil, and build out to 6, 9, or more supporting 50 or more antennas!Practically "plug and play", expansions are fast, minimize AM station impact, and maintain full grounding and lightning protection!Truly the state-of-the-art in AM collocation, backed by over 25 years of colocation experience!The LBA CoLoCoil AM Isocoupler system permits trouble-free colocation of all wireless antennas on AM broadcast antenna towers including directional arrays! With the CoLoCoil, most wireless installations have virtually no effect on the host AM tower, and the AM station has no effect on wireless system coaxial cables and antennas. CoLoCoil isocoupler modular systems are transparent to AC or DC voltages on coaxial cables. Thus, they present no problem to coaxial-powered tower top amplifiers, smart antennas, and other devices even supporting AC and strobe tower lighting systems!LBA CoLoCoil modular iscoupler systems are ideal for PCS, Broadband and Cellular collocation. They feature a unique patent-pending configuration that allows the addition of multiple coaxial cable modules. New antennas can be accommodated at any time without system redesign. Modules are factory-adjusted to minimize field set-up, and only high stability components are used to eliminate periodic readjustment. Rugged coaxial connectors used at the input and output are the only RF path connections used, virtually eliminating intermodulation. RF path reliability and performance is that of the coaxial cable alone! Each coaxial path is sweep tested and measured for insertion loss before shipment and the documentation furnished to the user.All modular CoLoCoil isocouplers are rated to work with AM RF voltages typical on AM towers of 10,000 watts or less. Custom systems are available for all AM power levels. Custom isocouplers accommodate high power levels, special configurations and performance. Even non-coaxial cables, such as for active antennas and tower lighting, can be incorporated in custom CoLoCoil co-location modules.CoLoCoil AM isocoupler modules are optionally equipped with a unique isolation and safety monitoring system. Front panel indicators permit instant visualization of isolation circuit status and RF presence. Alarm connections are provided for interface with site status and interlock systems.For safety of user personnel, CoLoCoil isocoupler modules are designed so that no high RF voltages are accessible. A highly effective RF grounding system eliminates the AM "hot cabinet" problem. Additional features of the system include color-coding of all coaxial input/outputs and numbering for ready circuit identification and user inventory. A direct DC static ground and rugged spark gap provide lightning protection.

Optosolar GmbH
For series connected multijunction cells, at a given spectrum (e.g. AM 1.5 or AM 0 for space solar cells), one of the cells will limit the current in the series connection of cells. All solar simulators deviate from the true AM 1.5 spectrum, and they are only classified in wide spectral bands (100nm width). So even for class A or A+ solar simulators, it can easily happen that the bandgaps of the multijunction cells are such distributed that the 'wrong' cell will limit the current, if a solar simulator with fixed spectrum is used. In the 70s and 80s, when these measurements were first developed, intercomparisons showed deviations of cell efficiency in fixed spectrum solar simulators of more than 40%.
