Why choose Communica for coaxial cable
When you need coaxial cable for RF, CCTV, satellite, or pro audio, the worst delay is waiting on overseas freight. Communica keeps local stock across Samrand, Pretoria and Cape Town so you can get the right cable quickly, collect from a branch, and receive a VAT invoice for procurement or education purchases. Our selection focuses on practical compatibility and fit-for-purpose specifications - not one-size-fits-all claims.
Key customer benefits
- Immediate branch pickup or next-day delivery from Samrand warehouse
- Clear spec sheets and compatibility advice for CCTV, satellite, and RF systems
- Account quotes and VAT invoices for institutions and procurement teams
Typical use cases we support
Students, makers and technicians commonly choose coax for three categories: CCTV/coax video (HD analog), satellite/TV distribution, and RF/antenna work. Each needs different impedance control, shielding and connector type. Browse our collections to see the range and stock status on cable types and connectors at the product level: Shop by Category.
Specification callouts to check before you buy
Never pick coax by appearance alone. Verify these specs on the product page or datasheet:
- Impedance (commonly 50 or 75 ohm) - match transmitter/receiver
- Attenuation at relevant frequency (dB/100m) - higher frequencies need lower loss
- Shielding (single braid, double braid, foil+braid) - affects noise rejection
- Jacket type (UV, outdoor-rated, fire-retardant) - installation environment matters
- Connector options and termination (BNC, F-type, N-type, SMA) - ensure mechanical fit
Quick compatibility table
| Application | Impedance | Typical Connector |
|---|---|---|
| CCTV / HD-TVI | 75 ohm | BNC |
| Satellite / TV | 75 ohm | F-type |
| RF / Antenna / Ham | 50 ohm | N-type, SMA |
