Ubiquiti IP67CA-RPSMA Weatherproof RP-SMA Cable Assembly
Overview
The Ubiquiti IP67CA-RPSMA is a weatherproof RF cable assembly purpose-built for outdoor Airmax wireless installations where moisture and dust exposure are unavoidable. The cable features IP67-rated connectors—meaning it can survive temporary submersion and sustained rain without signal loss or corrosion—a critical detail when you're mounting gear on towers, rooftops, or exterior walls where condensation and salt spray are constant threats. RP-SMA connector ends ensure compatibility with standard Ubiquiti Airmax radio units and antenna systems across Point-to-Point and Point-to-Multipoint topologies.
Key Features
- IP67-Rated Connectors: Dust and moisture ingress are blocked at the connector interface, preventing RF signal degradation over months or years of outdoor exposure. Unlike standard connectors that corrode or develop micro-fractures in wet environments, IP67 rating guarantees a sealed interface—essential when replacing or servicing gear without tearing down the entire tower install.
- RP-SMA Connector Type: Reverse-polarity SMA ends mate directly with Ubiquiti Airmax radios, eliminating adapter chains that introduce impedance mismatches and signal loss. Direct connection means fewer failure points and faster field swaps.
- Outdoor Environmental Durability: The cable assembly withstands UV exposure, temperature cycling, and wind-driven rain without degradation. This matters on multi-year tower leases where UV-brittle or poorly sealed cables fail mid-season and require emergency replacement—downtime you can avoid by specifying this cable upfront.
- RF Signal Integrity: Sealed connectors preserve signal continuity in high-humidity or salt-spray environments (coastal deployments, wet climates). Signal degradation from connector oxidation is one of the most common silent failures in outdoor wireless—this cable eliminates that failure mode.
- Tower and Rooftop Installation Ready: Designed for vertical and horizontal mounts where water pooling and wind loading are normal. The weatherproof seal means you don't need to tape, conformal coat, or jury-rig secondary protection around connectors.
- Field-Replaceable Without RF Loss: When swapping radios or antennas, the IP67CA-RPSMA (often searched as IP67CA RPSMA) can be disconnected and reconnected multiple times without corrosion buildup preventing clean mating—a practical advantage over standard cables that corrode after one or two field disconnects.
Integration & Deployment Context
This cable integrates into Ubiquiti Airmax networks of any scale—from small two-node Point-to-Point backhauls to multi-sector Point-to-Multipoint distributions. It pairs with any Ubiquiti Airmax radio (NanoStation, LiteBeam, PowerBeam, or similar) that uses RP-SMA antenna connections. For outdoor wireless system planning, this cable is a foundational component: undersizing weatherproofing on connectors is a common cost-cutting mistake that results in field failures within 12–24 months. Specifying IP67-rated RF cabling upfront eliminates that risk.
Tower-mounted and rooftop deployments benefit most—any site where the cable runs exposed to rain, spray, or condensation should use IP67-rated assemblies rather than bare or poorly sealed alternatives. Wall-mounted outdoor installations also benefit, particularly in humid or coastal regions.
Frequently Asked Questions
Q: Will the IP67CA-RPSMA work with my existing Ubiquiti Airmax radio?
A: Yes, provided your radio has RP-SMA antenna connectors. Most Ubiquiti Airmax models (NanoStation, LiteBeam, PowerBeam series) use RP-SMA. Verify your radio's port type in the product manual before ordering.
Q: Can I use this cable indoors?
A: Technically yes—IP67-rated connectors work indoors without issue. However, this cable is specifically engineered for outdoor weatherproofing. Indoors, standard RP-SMA cables are adequate and more cost-effective.
Q: How long does the connector seal last?
A: IP67 seals on Ubiquiti connectors are rated for the operational life of the assembly. Field experience in outdoor tower deployments shows 3–5+ years of reliable service with no seal degradation, assuming the cable is not physically damaged.
Q: Will the IP67CA-RPSMA handle UV exposure on a tower?
A: The cable is UV-resistant, but for multi-year tower leases (5+ years), consider protective conduit or UV-blocking spiral wrap around exposed cable runs. The connectors themselves are hardened against UV; the cable jacket will outlast standard polyethylene assemblies.
Q: Can I extend this cable with standard RP-SMA extensions?
A: You can, but each added connector introduces a potential failure point. If extension is necessary, use additional IP67-rated connectors to maintain weatherproofing. Avoid mixing IP67 and standard connectors in the same run.
Q: Is this cable suitable for coastal salt-spray environments?
A: Yes—IP67-rated connectors resist corrosion from salt spray better than standard connectors. For extreme coastal salt-spray sites, consider conformal coating the connector bodies as an additional precaution, but the IP67 seal is the primary defense.

The IP67CA-RPSMA solves a specific and expensive problem: RF connector corrosion in outdoor wireless. Most integrators discover this issue too late—after six months on a tower, a standard connector develops micro-oxidation that degrades SNR by 3–6 dB, forcing either a costly tower visit to replace the cable or acceptance of reduced throughput. The IP67 rating on the IP67CA-RPSMA's connectors eliminates that failure mode entirely.
Technical Highlights:
- IP67 Connector Sealing: Prevents moisture and dust ingress at the interface—the point where corrosion begins. On tower-mounted radios exposed to condensation cycles and wind-driven rain, this seal is the difference between a 3–5 year field life and a 6–12 month failure cycle.
- RP-SMA Compatibility: Direct mate to Ubiquiti Airmax ecosystems (NanoStation, LiteBeam, PowerBeam, and sector antenna arrays). No adapters needed; fewer impedance discontinuities means measurable RF efficiency gains—2–3 dB improvements are common when you replace deteriorating standard connectors with IP67-sealed alternatives.
- UV-Resistant Cable Jacket: Outdoor cable runs are exposed to constant UV bombardment. Standard polyethylene jackets become brittle within 2–3 years; this assembly's jacket outlasts the connector seal, reducing premature field replacements.
Deployment Considerations:
- This cable is a preventive component, not a performance upgrade. Its value is in avoiding failures, not boosting throughput. Budget for it upfront in any multi-year outdoor wireless lease.
- Watch for: integrators sometimes pair IP67-rated cables with standard (non-sealed) antenna connectors. The weakest point in the weatherproofing chain will fail first. If you're specifying this cable, audit your antenna terminations too—they must also be IP67 or sealed equivalents.
- Salt-spray and coastal deployments: IP67 seals resist corrosion, but conformal coating the connector bodies adds insurance for high-salinity environments. Plan for that cost on coastal contracts.
The IP67CA-RPSMA is a standard choice for tower integrators and wireless consultants building 3+ year outdoor Airmax networks in wet or humid climates. It's not exciting, but it's reliable—and in field deployments, reliable is what pays the bills.
