Struggling with Extending CoAxial Cable For a Sensor

[artistwantab]

Hey guys!

I need to extend 2.5c-2v Coaxial Cable. All the searches online and emailing a few wiring companies have left me empty.

I need to extend blind spot sensors on a custom a custom RV I am building.

Can I up size coaxial wiring? If so is there a way of connecting the too. I could solder but coAxial doesn't normally like heat.

I would use a pair of female f connectors and a double male coupler to extend the coax, and solder and heat shrink on the power side

It's automotive, so we'll be talking smaller coax cable than F connectors.

OP, got any photos?

Here you go!

This is the end part. The part that connects to the control box for the sensors.

Ahh sorry I misread the first post, for the ones that don't reach, why not buy new plugs from somewhere like cpc and cable and make up fresh leads? Or just buy off the shelf long coax leads?

Nothing available. I looked and essentially it isn't a problem for a normal car. But being this is for an extended RV I couldn't find anything.

How long does it need to be and is it standard coax male on each end

The proper way would be to fit small coax connectors (SMA etc). However I reckon you will probably get away with soldering in this case. But keep the joint as short and neat as possible.

I can't locate 2.5c-2v Coaxial Cable. Could I upsize coaxial?

You could use an alternative cable yes. I wouldn't necessarily go bigger though.

I presume the sensors don't work at a very high frequency? If not then any decent miniature coax cable should be fine.

2.5c-2v cable (Japanese numbering system) appears to be standard 75ohm CCTV cable.
I'm more familiar with the RG numbers used in UK

I think any 75ohm co-ax will do the job, but I guess you are looking for similar diameter

Mini RG-59 cable is 75 ohm and a similar size to yours. I think it has good enough electrical characteristics for your use, but a tinned steel core rather than copper, don't know if that matters in a vehicle!

I suggest soldering a joint (carefully!) is the way ahead!

Thank you.

This is what I needed. I will give it a chance and hopefully it works.

I'm wondering if there might be a limit on the length the cable can be extended to - is it possible to move whatever the sensors connect to closer to them and extend the outputs of that?
