I bought the Peet Bros one at Dayton this year.
I put the anamometer (wind thingie) at the top of my 100' tower.
The included cable was about 40'.  I added, oh, about 200' to
that with cheap 4 conductor, non-shielded telephone wire.  It's
run in the same conduit as my RG-8 cables (80/160M) and right next
to my CATV (10-40M) runs.  I also use the tower as a shunt-fed
vertical on 160M.  I run 1500W on all HF bands, all modes.

I've never had any RFI problems with the display unit or the readings.

Also, the Peet Bros unit only restricts the length of the outdoor
temp sensor, not the wind unit, as they are seperate sensors.  The
wind sensor is just contact closures, whereas the temperature is
dependant upon resistance, and adding long conductors will add
resistance, thereby changing the "temperature".
