Radio-TV-Video Cables & Connectors - Local Stock for South African Makers

Fast access to Radio-TV-Video components for projects and installs

Get the right cables, connectors and accessories for radio, TV and video projects without long waits. Communica stocks a wide range of coaxial cable, BNC, RCA, F-type and SMA connectors plus antennas and test leads - helping makers, students and technicians complete prototypes, lab work and field installs faster. With branch collection in Samrand, Pretoria and Cape Town, plus VAT invoices and account quoting for institutions, you can source components locally with predictable lead times.

Why choose local stock for RTV work

• Immediate pickup from Samrand or nearby branches reduces project downtime.
• Clear invoicing for tertiary labs, student projects and procurement teams.
• Accessory bundles and compatible parts simplify builds and testing.

Common RTV items stocked include RG-58 and RG-6 coax, quad-shield cable, BNC crimp and compression connectors, RCA plugs, F-type satellite connectors, SMA antenna leads and patch cables. Popular maker-friendly brands and supplier lines are also carried - use our Shop by Brand page to explore options and compare parts.

Not sure which cable or connector you need? Start with the signal type and environment: terrestrial TV and DVB-T typically use RG-6/F-type, analogue video and test equipment often use BNC/RG-58, while RF prototyping may use SMA jumpers. For lab work, choose flexible, low-loss cable for short runs and higher-spec quad-shield or solid-centre RG-6 for long runs or external feeds.

Connector selection tips

• Match impedance (50 vs 75 ohm) to equipment to avoid reflections.
• Choose compression connectors for outdoor/coax installs for better weather resistance over basic crimp types.
• Confirm plug gender and thread type on SMA/RP-SMA to prevent mismatches.

If you need in-person guidance, our branch locations and hours are listed on the branches page for easy planning. Visit Branches & Trading Hours to check stock pickup and opening times.

Compatibility, bundles and project-ready accessories

Communica groups compatible parts and accessories so you can buy a complete solution: cable reels, crimp/compression tool kits, termination fittings and test adapters. For students and labs, select pre-cut lengths and lab-friendly patch leads to keep setups repeatable and tidy. We also provide product spec callouts on category pages to help match voltages, impedance and connector types without guesswork.

Common wiring diagrams and simple examples

Troubleshooting tips

• Faulty picture or intermittent signal: check connector crimps and outer shield continuity.
• High noise on long runs: consider higher-spec RG-6 or a low-loss coax option.
• Mismatched connectors: inspect impedance and connector gender before purchase.
