Available in two connector configurations—the \u003cb\u003eDSPSFR2ON300CI\u003c\/b\u003e featuring standard Type-N Female ports and the \u003cb\u003eDSPSFR2OMD300CI\u003c\/b\u003e featuring compact 4.3-10 Female ports—the assembly maintains an ultra-low passive intermodulation rating of ≤-161 dBc @ 2 x 43 dBm to eliminate intermodulation noise and protect receiver sensitivity on multi-carrier donor feeds. Certified dust-tight and weatherproof under IEC Standards (IEC 60529 IP66) and tested for commercial electrical safety under UL Standards (UL 62368-1), the rugged passivated aluminum enclosure operates across extreme ambient temperatures from -35°C to +85°C (-31°F to +185°F). Built to comply with emergency communications guidelines under NFPA 1221, NFPA 1225, and OSHA Standards, each unit includes integrated mounting flanges for secure installation on equipment backboards, walls, and overhead cable trays.\u003c\/p\u003e\n\u003ch3 dir=\"ltr\"\u003eKey Features \u0026amp; Benefits\u003c\/h3\u003e\n\u003cul dir=\"ltr\"\u003e\n\u003cli\u003e\n\u003cb\u003eTwo Precision

Because it contains no resistive elements to absorb power, it achieves significantly lower insertion loss, higher power handling (up to 300W continuous), and superior passive intermodulation (PIM) performance compared to Wilkinson splitters. However, reactive splitters do not provide isolation between output ports and are designed specifically for branching power to separate antennas.\u003c\/p\u003e\n\u003ch4 dir=\"ltr\"\u003eWhy is Low PIM (Passive Intermodulation) important in public safety BDA and DAS networks?\u003c\/h4\u003e\n\u003cp\u003ePassive Intermodulation occurs when multi-carrier high-power RF signals pass through non-linearities in passive components, generating phantom interference signals that fall back into the uplink receiver bands. The DSPSFR2 Series delivers an exceptionally low PIM rating of ≤-161 dBc, preventing receiver desensitization and ensuring public safety transceivers maintain clear audio during critical emergency transmissions.\u003c\/p\u003e\n\u003ch4 dir=\"ltr\"\u003eCan this power splitter be installed outdoors?\u003c\/h4\u003e\n\u003cp\u003eYes. Both units are housed in heavy-duty extruded aluminum enclosures certified to an IP66 ingress protection rating. When the RF connectors are properly weather-sealed with butyl mastic and electrical tape, the splitter can be mounted outdoors on rooftops, antenna masts, or external building walls.\u003c\/p\u003e\n\u003ch4 dir=\"ltr\"\u003eCan this splitter be used in reverse as a power combiner?\u003c\/h4\u003e\n\u003cp\u003eBecause reactive splitters lack isolation between the two branch ports, they should not be used to combine two active, unsynchronized transmitters. However, for receiving systems or combining identical phase-matched coherent signals, reactive devices can function bi-directionally.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003ch3 dir=\"ltr\"\u003eWarranty\u003c\/h3\u003e\n\u003cp dir=\"ltr\"\u003e1-year manufacturer’s replacement warranty.\u003c\/p\u003e","brand":"Motorola","offers":[{"title":"DSPSFR2ON300CI (Type-N)","offer_id":68050381832366,"sku":"DSPSFR2ON300CI","price":79.99,"currency_code":"USD","in_stock":true},{"title":"DSPSFR2OMD300CI (4.3-10)","offer_id":68050381865134,"sku":"DSPSFR2OMD300CI","price":87.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0062\/0845\/4744\/files\/DSPSFR2OMD300CIa.png?v=1794416218","url":"https:\/\/www.atlanticradiocorp.com\/products\/motorola-dspsfr2on300ci","provider":"Atlantic Radio Communications Corp.
