Why choose local radio, TV & video supplies in South Africa

Finding the right radio, TV and video components matters when projects need to work first time. Communica offers a wide selection of RF connectors, coaxial cable, video baluns, power supplies and test equipment stocked in South Africa so you can keep projects moving with minimal lead time. Local stock means faster branch collection, VAT invoicing for institutions, and easier procurement for tertiary labs and engineering teams.

Key practical advantages

  • Fast access to components from brands makers and technicians trust - from connectors and enclosures to test & measurement tools.
  • Visit or collect from Samrand head office/warehouse, or check availability at Pretoria and Cape Town branches.
  • Account quotes, VAT invoices and education purchasing support simplify procurement for universities and labs.

Common product groups for radio, TV & video projects

Whether you are building an FM receiver, a CCTV install, or a composite video test rig, start by browsing core categories to size and match parts quickly:

  • Coax & cable assemblies - RG59/RG6 options for video, with impedance notes for compatibility.
  • RF connectors - BNC, F-type, SMA for antenna and test connections.
  • Power solutions - regulated DC supplies sized for set-top boxes, modulators and cameras.
  • Test & measurement - spectrum analysers, signal generators and multimeters for alignment and troubleshooting.

Specification callouts and compatibility guidance

Match impedance (75 ohm for most consumer video, 50 ohm for RF test and some radio use). Confirm connector gender and thread type before ordering. For CCTV and analogue video, check whether the system expects composite video (RCA/BNC) or HD-SDI/HDMI signalling and choose cabling accordingly.

For an overview of ranges and categories, explore our collections to see available product types and brands, which helps shorten specification to purchase time: Shop by Category and the All Products index.

Quick spec calculation examples

Use Ohm's law and power calculations when feeding amplifiers or distribution amps. Example formulas:

V = I × R (voltage = current × resistance) | P = V × I (power = voltage × current)

If a camera requires 12 V at 500 mA (0.5 A): P = 12 V × 0.5 A = 6 W. Choose a power supply rated above 6 W (e.g., 12 V, 1 A) to allow headroom.

Selecting parts, troubleshooting and accessory bundles

Choose parts with practical installation in mind: pre-terminated coax for quick installs, screw-on BNCs for field repairs, and weatherproof enclosures where cameras will be exposed. We stock maker-friendly brands and industrial names so you can pick components that fit your workflow and budget.

Wiring diagram (simple composite video with power)

A common CCTV feed uses a single coax carrying video and a separate DC power line. Example ASCII wiring for clarity:

Camera ----- BNC ----- Coax ----- BNC ----- DVR
           \-- GND ----+                    
Power supply +12V ----- DC jack -----------------

Troubleshooting tips

  • No picture: check connector seating, impedance mismatch, and power to camera.
  • Noise or ghosting: inspect cable length/quality and use proper 75 ohm connectors for video runs.
  • Intermittent signal: test with a multimeter or signal generator from the test equipment range.

Bundles and accessories that save time

Consider pre-made starter kits: coax & connector bundles, CCTV power kits, and test tool combo packs for student labs. These reduce assembly time and ensure component compatibility for classroom or workshop use. See our brand index for compatible maker gear and accessories: Shop by Brand.
