BK-12E
Please Register or call for more information
The BK-12 series diplexer combines, or separates, signals in the 80–960 MHz and 1695–2700 MHz bands, so two systems can share a single cable and antenna. The low-band port covers VHF and UHF land mobile radio, TETRA, 700/800 MHz public safety including P25 and FirstNet Band 14, and 600–900 MHz LTE and 5G. The high-band port covers AWS, PCS, WCS, n41, DCS, IMT, and IMT-E mid-band LTE and 5G.
This makes the BK-12 a simple way to add public safety coverage to an existing cellular DAS or feeder line, or to run both on new shared infrastructure, without adding cable runs or antennas. Low-PIM construction and an IP67 housing suit it to high-power in-building, tunnel and outdoor installations.
