BNC Female Panel Mount to 90° SMA Male Pigtail | RG179 RF Extension Cable, 75Ω, Low-Loss for Broadcast & Video Systems
Meta Description (SEO):
Factory-direct BNC female panel mount to 90° SMA male pigtail cable using RG179 (75Ω) coax. Precision-engineered for broadcast, CCTV, and satellite systems. ROHS-compliant, low VSWR, and panel-ready. Ships in 48 hours.
Purpose-Built for Broadcast & Video Signal Integrity
This specialized RG179 pigtail cable bridges BNC female panel-mount interfaces (e.g., chassis, enclosures) to 90° SMA male connectors (e.g., cameras, modulators, test gear). Engineered for 75Ω systems like HD-SDI, satellite LNBs, and CCTV, it minimizes signal reflection with VSWR ≤ 1.15:1 and ≤ 0.35 dB insertion loss @ 1 GHz. The 90° SMA bend saves space in tight installations, while the BNC panel mount ensures secure chassis integration. Note: RG179 is 75Ω—unsuitable for 50Ω WiFi systems (e.g., 2.4/5/6 GHz).

1. 75Ω Impedance Match
RG179’s 75Ω impedance aligns perfectly with broadcast/video standards (e.g., HD-SDI, satellite LNBs), eliminating signal reflections that cause pixelation or dropouts in 50Ω cables.
Critical Warning: Do not use in 50Ω systems (e.g., WiFi, cellular). Mismatch causes >20% power loss.
2. Panel Mount Reliability
BNC female connector includes 0.375"-32 UNF threading for secure panel mounting (fits standard 0.406" holes).
Hex flange allows wrench tightening to 25 in-lb torque—prevents vibration loosening in industrial environments.
3. 90° SMA Male Advantages
Right-angle design fits tight spaces (e.g., behind cameras, inside modulators).
SMA’s threaded coupling (vs. BNC’s bayonet) ensures stable connections in high-vibration setups.
4. RG179 Performance Edge
30% lower loss than RG59 at 1 GHz—critical for long HD-SDI runs.
Foamed PTFE dielectric maintains signal integrity up to 3 GHz (supports 4K video).
Broadcast: HD-SDI camera connections, video routers, signal distribution.
Satellite Systems: LNB to IRD (Integrated Receiver/Decoder) links.
CCTV/Security: Connecting PTZ cameras to NVRs in confined spaces.
Test Equipment: Calibrating spectrum analyzers for 75Ω video signals.
Medical Imaging: Ultrasound/MRI signal routing (where EMI resistance is critical).
1. Panel Mount Precision
BNC connectors machined to ±0.05 mm tolerances for flush panel fit.
Torque-tested to 25 in-lb (exceeds MIL-STD-348).
2. 100% Electrical Validation
VSWR/insertion loss verified up to 3 GHz via vector network analyzer (VNA).
DC continuity and insulation resistance (≥ 500 MΩ) tested per IEC 60227.
3. Environmental Durability
Cables pass 500+ mating cycles (SMA connector) and -40°C to +85°C thermal cycling.
Standard Packaging: Coiled in anti-static bag with connector caps; label includes impedance (75Ω), part number, and test data.
Lead Time: 48 hours for 15 cm stock length; 5–7 days for custom lengths.
MOQ: None for standard specs (1+ units). Custom lengths: 10+ units.
Bulk Orders: Palletized with custom labeling (e.g., project-specific barcodes).
Q1: Can this replace RG58 (50Ω) in WiFi systems?
A: Absolutely not. RG179 is 75Ω—using it in 50Ω WiFi systems (e.g., routers, access points) causes severe signal loss (>20%) and VSWR spikes. Only use for 75Ω video/satellite applications.
Q2: What panel thickness does the BNC mount support?
A: Fits panels 0.06–0.25 inches thick. Flange design accommodates standard sheet metal (e.g., 1.5–3 mm enclosures).
Q3: Is RG179 suitable for 4K video?
A: Yes. Supports 3G-SDI (2.97 Gbps) up to 150m without repeaters. For 12G-SDI (8K), use shorter lengths (<50 cm).
Q4: Can I request a different angle (e.g., 180°)?
A: Yes. 90° is standard, but 180° SMA options available (+3 days lead time).
Confirm 75Ω Requirement: Verify your system uses 75Ω (e.g., HD-SDI, satellite). Never force-fit into 50Ω gear.
Panel Hole Size: Ensure chassis hole is 0.406" (10.3 mm) for BNC mounting.
Length Limits: For runs >50 cm, consider active repeaters (signal loss exceeds 1.5 dB @ 3 GHz).
