Has anyone tried to extend the 40 ft anemometer cable supplied with the wireless Vantage Pro 2 ? Also can the cable be buried as long as the connector for the extension is waterproofed?
I need to run mine approximately 60 ft.
I know that there is a wireless solution to this, but I figured it would be less expensive if I could use the cable.
Thanks,
Jerry :)

Hi Jerry...
Well, you could of course buy the extra long cable that Davis makes--I don't recall exactly, well, I'll just look it up right now... it's 100'.
I have thought about splicing my own extension as well...
Provantage has the 100' extension for less than $36 (I didn't get a discount price quote), and it includes a waterproof coupler...
You won't notice that extra amount for the purchase you're looking at! I can help you spend your money!! :lol:
Unless you've already got the equipment to make a connection for 4 conductor cable, I'd apply that expense to buying the pre-made extension...
I wouldn't think having the cable underground is any worse than out in the open being exposed to all weather... but..... I might consider using conduit anyway...
Alright! You really are on the path!
Marc
P.S. Now that I'm thinking about it, you could probably find various lengths of 4-conductor plus waterproof connectors at Lowes or Home Depot--I'll have to check it out this weekend myself...

According to the Davis manual, you can extend the anemometer cable up to 540' without impacting max measurable wind speed readings. I don't see anything about burying the cable. Davis Support should be able to answer that question if others in this forum don't know. The cables available from Davis come with waterproof coupler kits (see the following link for details: http://www.davisnet.com/weather/products/install_cables.asp). You could always use small pvc pipe and feed the cables through it to keep any water out.

Thanks Marc and Don for your information.

Jerry for what its worth when I had a WMII I buried my cables for the annie in pvc. Just extra protection for the long run. But, about a year later the annie went bad and I had to send it in for repair. It was a pain in the butt digging all that ground up. I know its cheaper to use the cable but if you ever have to dig it up to get repaired you'll know what I mean.
