R-F Coaxial Connectors Price Guide - Buy RF Coax Connectors in South Africa

Find the right RF coaxial connector without delay

If you need RF coaxial connectors now - for prototyping, lab test rigs, RF modules, or IoT gateways - Communica keeps a broad range of connectors and accessories in local stock so you can keep projects moving. Our focus is on practical value: clear pricing, spec comparisons, and local services like branch collection in Samrand or Pretoria and formal VAT invoices for institution purchases.

Why price varies and what matters most

Connector price depends on type (SMA, BNC, N-type, MMCX, RP-SMA), material and plating (nickel, gold), frequency rating, mechanical durability, and whether it’s PCB-mounted, cable-mounted or panel-mounted. Low-cost options suit classroom work and quick prototypes; higher-spec types are better for repeatable lab measurements and RF installations. We present clear pricing tiers so you choose based on application rather than guesswork.

Accessory bundles and compatibility tips

Buying connectors often means you also need cable assemblies, solder/ crimp tools, and adapters. We offer bundles that combine SMA/RP-SMA connectors with pre-crimped RG-174 or RG-58 pigtails and adapter pairs. For antenna projects, confirm your module’s gender and whether it uses reversed polarity (RP-SMA) before ordering. If you prefer to browse stock before committing, check our main catalogue for all available parts here.

Local availability and lead times

We maintain stock at our Samrand head office and branch warehouses. Popular connector types are usually available for same-day collection from Samrand or Pretoria CBD; less common, specialised connectors may require a short lead time. For branch hours and collection details, see our branches page here. If you need brand-specific parts (e.g., Amphenol-style or maker-friendly Adafruit accessories), use our shop-by-brand index here to narrow choices.

Specification callouts to check before you buy

• Type & gender (SMA vs RP-SMA, male/female)
• Impedance (50 ohm typical for RF)
• Frequency rating and VSWR if specified
• Cable compatibility (RG-174, RG-58, etc.)
• Mounting style (PCB, panel, cable)

Price transparency, quotes and procurement for South African buyers

We support students, makers and procurement teams with clear pricing and formal quotations. For bulk orders or tertiary lab purchases, request a structured quote and VAT invoice for departmental procurement. Need an estimated lead time or volume discount? Use our Request a Quote path and one of our team members will confirm stock and delivery estimates.

Compatibility checklist and quick calculations

For RF path loss and power handling planning, remember basic calculations: Ohm’s law remains useful for DC feed lines, while insertion loss and return loss govern RF performance. Simple reminder formulas:

Ohm’s law: V = I × R

Power (DC): P = V × I

For connector insertion loss, consult the datasheet; typical small coax connectors add 0.1-0.5 dB at low GHz ranges depending on quality.

Troubleshooting common connector issues

Poor connection or intermittent RF often comes from incorrect mating, worn centre pins, or improper cable crimping. Inspect for bent pins, ensure correct torque for threaded connectors, and use the right crimp ferrule size. For test setups, use quality adapters sized for your frequency band to avoid excessive VSWR.

Objections handled - why buy local from Communica
