Before you believe a bad review about us

We would like to respond openly to every negative review about us. Many are posted anonymously, so we cannot reach those customers directly. This open letter is our reply, and we would be grateful if you took a moment to read it.

But here is what a one-star review will never tell you:

  • We import from 70+ official distributors. That is why you pay far less than local retail — and why delivery takes longer. We publish the date before you pay, never after.
  • You can pay only when your goods land in Johannesburg. Pay on Arrival, no full payment up front. Ask yourself what scammer offers that.
  • Nobody has ever lost money with us. You get the product, or you get a refund. There is no third option, and there never has been.
  • We are part of the ITwork group — ten years trading in Europe, nine stores, thousands of positive reviews.
  • Johannesburg and Cape Town stores open this year — real shelves, real stock, walk in and buy the same day.

We are not satisfied with our review scores, and we are not going to fix them by hiding anything. We are fixing them by being faster, clearer and easier to reach than any reason to complain.

Read the full letter — photos and video of real shipments, and a straight answer to every accusation.

With a shielding effectiveness exceeding 90 dB, the Renkforce SKB 488-20 coaxial cable ensures your satellite, DVB-T, and cable TV signals arrive with minimal interference, even over a generous 20-metre run. This double-shielded 75-ohm cable is built for reliable, high-quality transmission in both residential and commercial installations.

Overview

The Renkforce SKB 488-20 is a bulk coaxial cable supplied without connectors, giving you the flexibility to terminate it exactly as your installation requires. Its white PVC jacket blends neatly into most environments, while the foamed polyethylene dielectric and solid copper inner conductor maintain signal integrity across the full frequency range. Whether you're wiring a new satellite dish, extending a cable TV outlet, or setting up a DVB-T antenna, this cable delivers consistent performance.

What stands out

  • Double shielding with aluminium foil and copper braid for superior interference rejection.
  • Low attenuation: only 10.5 dB/100m at 100 MHz, rising to 52.5 dB/100m at 2050 MHz.
  • Solid copper inner conductor (0.5 mm diameter) for excellent conductivity.
  • Flexible 5 mm outer diameter with durable PVC jacket.
  • 20-metre length ideal for longer runs without splices.
