The VP2 comes with a 40 foot anemometer cable, and can be extended. Davis sells 100' cords that can be joined to the 40'. (I'm not sure if it's just standard straight through phone wiring or what, I think it's discussed somewhere on the wxforum.net Vince referenced). There's just this caveat (https://cdn.shopify.com/s/files/1/0515/5992/3873/files/7876_spec_4Con_Rev_D.pdf):
"Maximum wind speed reading decreases as the length of the cable increases. At 140' (43 m) maximum speed is 175 mph (78 m/ s). At 340' (104 m), maximum speed is 70 mph (31 m/s). The accuracy of the reading below the maximum is not affected." Therefore you wouldn't need to worry about batteries at that height, you should be good until the bearings go bad, which hopefully would be many years. I believe Tom is correct, the rain gauge is not made to be detached, though maybe you could figure out a way to do it, and even if you could I don't know how elegant it would be. However I've read (on wxforum again) that some have hooked up a stand alone Rainwise rain gauge to their VP which they claim is more accurate, so I guess how far away you want it from the ISS depends on how long your cable can be. A good part of the year here I cover the gauge and measure moisture from a manual gauge and have to add it manually to the WeeWX database anyway. However inaccurate the gauge may be to begin with, I think it would even be worse trying to measure snow with or without a gauge heater.
