Extending Anemometer Cable

[Kafinater]

I've been trawling around trying to find something best suited to my need and there have been some helpful posts. However, I've not been confident enough to go and buy the cable knowing I'm getting the right stuff.

My Weather station is the one from Maplins that comes with the WH1081 unit so ideally I need someone to reply who has this model and has extended the cable!!

I really need to put the wind tools on the roof and I know I don't need anymore than 20 metres of cable. Looking at the cable that links up to the transmitter (Temp/humid sensor) its fairly thin, not like ethernet cable, and looks very similar to the phone cable coming into my house! The plug is a small, probably RJ11 plug and I can see 4 gold connectors.

I've seen some people say Cat5e etc can be used but the ethernet plug is too big. I've seen some say they used ADSL cable and then I was confused by one "expert" saying you need to be sure that the wired pairs match up with the pairs of existing connections....
Oh, and just to add to the confusion I've heard some say that the signal will be significantly reduced over 20 metres and may give a wrong reading....

SO, please someone put me out of my misery, hit me with a positive answer of what cable I need!!! Pictures maybe included!!

I've used normal ADSL extension cable with a socket at one end and a plug at the other. I have put 2x 5m ones together to extend 10m with no apparent problems.
The link below is what I bought from amazon, as you will see not very expensive.

One thing I would say is that you should ensure the connections are well protected from the weather, I run mine in plastic conduit and used through boxes to house the connections and sealed the ends with bathroom sealant.

Richard, thanks for that. I went to the link and changed the search to 20M and found what I'm looking for at £5.99 a much better deal than the £30 Maplins offered me!

As far as the weather proofing is concerned yes, I realise that being outdoors and the cable designed more for indoors use, weather damage could be an issue. I've already spoken to a plumber/builder mate with a big ladder who will be able to do most of the work for me.

While I'm here, I also clicked on your weather link and quite liked your presentation and wouldn't mind adding something like that to my own web space.

My website is really just some design changes from the web pages that cumulus comes with. It has taken me maybe a year to get to what you see. I knew nothing about HTML when I started, I have just used trial and error and a few Google searches. The link below has been very useful.

If I can do it, I'm sure anybody can. Just have a go and don't give up if it doesn't go right the first time.

Good luck!
