Why local stock matters for broadcasters and AV technicians

Working in Johannesburg means tight schedules and on-site fixes. Having components available nearby reduces lead times, helps meet installation windows and keeps student and lab projects on track. We stock brands and categories that installers and makers commonly request, so you can Compare Specs and assemble accessory bundles quickly.

Typical items you’ll find

• Coaxial cables and BNC/Radio frequency connectors
• Video connectors, adapters and HDMI patch cables
• Power adapters, regulated DC supplies and replacement AC adapters
• Test & measurement tools for RF and video (signal generators, multimeters)
• Mounting hardware, enclosures and patch panels

If you’re not sure what to pick, our product pages and category guides make specification matching easier. Browse our collections for a quick overview: Shop by Category, explore brands we stock at Shop by Brand, or view our full inventory at All Products.

Specification callouts to check before you buy

When choosing radio, TV and video parts, confirm key specs to avoid returns and rework. Compare impedance (50 vs 75 ohm), connector type (BNC, SMA, F-type), cable shielding, voltage and polarity on power supplies, and maximum supported resolution for video links. If you need help, Request a Quote and our team will confirm compatibility and suggest accessory bundles that save time on-site.

Compatibility guidance and accessory bundles

Mixing connector types or mismatching impedances can cost time on-site. Use compatible connectors and match cable impedance to the system (e.g., 75 ohm for most TV/video coax). For multi-device setups, choose a bundled approach: cable + connectors + strain relief + test lead. We assemble bundles for broadcast racks, CCTV installs, and AV classrooms to simplify procurement. You can Compare Specs on product pages or Request a Quote for a tailored bundle.

Troubleshooting common site problems

Many field issues come down to a few repeat causes:

• Signal drop: check cable length, type and connector integrity.
• Intermittent video: inspect connectors for bent pins and ensure proper termination.
• No power: confirm adapter voltage, polarity and connector fit.

Simple test formulas and checks help. Use Ohm’s law for basic power checks: V = I × R. For power adapters, calculate required wattage: P (W) = V (V) × I (A). A quick continuity check with a multimeter can confirm cable integrity before installation.
