View DetailsCoaxial Connector In Practice
A coaxial connector is a short length of transmission line with the same impedance as the cable, and every place that assumption breaks down shows up as a reflection. Matching the connector to the exact cable construction is not a formality; it is the whole job.
Problems This Range Solves
- Reflections caused by connectors that do not match the cable construction
- Water ingress at outdoor connections
- 50 and 75 ohm parts mixed on the same system
- Field terminations done without the correct preparation tool
- Instrument ports damaged by over-tightening
Who It Is For
- RF and wireless installation contractors
- Broadcast and CCTV installers
- Test and instrumentation laboratories
- Antenna system integrators
- Distributors supplying RF consumables
Where It Is Used
- Terminating feeder at an antenna or at equipment
- Building RF jumper assemblies
- Patching video and instrumentation signals
- Test bench connections on measurement equipment
- Maintenance replacement of a corroded outdoor connector

Where This Range Is Specified
Specifying and Handling Coaxial Connector
Before You Order
- Match the connector to the exact cable construction, not just the diameter
- Use the correct preparation tool; hand-trimmed feeder rarely terminates well
- Check impedance is consistent across the whole system
On Site
- Weatherproof every outdoor joint with tape or a boot
- Torque to the stated value rather than as tight as it will go
- Sweep the assembly after termination to confirm return loss
Coaxial Connector Questions
How do I choose the right connector for my feeder?
By the exact cable construction, not just the nominal size. Send us the cable part number and we will confirm the matching connector, because a connector intended for a different dielectric will not give the return loss you expect.
What is the difference between 50 and 75 ohm BNC?
The internal geometry differs even though the bodies look similar. Mixing them on a video path causes reflections that show as ghosting, so keep the two stocks physically separated.
Are weatherproof versions available?
Outdoor types include sealing provision, and every outdoor joint should additionally be taped or booted. Water ingress is the most common failure mode on mast-mounted connections.
Do I need a special preparation tool?
Yes for feeder connectors. The cable has to be cut and stripped to defined dimensions, and hand trimming is the usual reason a termination fails its sweep.
Can you supply pre-terminated jumper assemblies?
Yes, cut and terminated to your length with the matching cable, which removes field termination from the critical path.
