Polo Marconi Multi-Band Site Combiner — Multi-Band Combiner for LTE, VHF and UHF Co-Location
Technical specifications
Technical overview
The Polo Marconi multi-band combiner system is the site infrastructure solution for telecommunications towers that must simultaneously host transmitters from different technologies and frequency bands on a single shared site antenna. Co-location of a cellular operator's LTE transmitter, the PNP P25 radio, and the municipality emergency communications VHF system on the same tower and antenna is the typical scenario enabled with guaranteed inter-band isolation > 80 dB.
The modular design allows configuring the combiner from 2 to 8 bands by selecting cavity filter modules for each band. Each filter module has insertion loss less than 1.2 dB — at 200W input power this represents less than 54W heat dissipation per band, passively manageable without fans in most Peruvian installation climates.
For critical communications tower operators who must comply with MTC regulations on shared infrastructure installation, and for municipalities and regional governments seeking to consolidate emergency communications and cellular infrastructure in a single installation, the Polo Marconi multi-band combiner provides the technical component that makes consolidation possible without compromising any co-located system's performance.
