I got the The Weather Channel WS-9077U-IT from Amazon.com because I was tired of my other flaky weather stations. Thus far this weather station has by far the best range of any I've used. This is mainly because it uses the 900 MHz spectrum (915 MHz, to be exact). The model of the wireless sensor is TX29U. On the package it claims a 330 foot range, but I'm just happy it works in the patio of the house which is about 60 feet away from the base station with two walls in between. In comparison, the pathetic Lacrosse WS-7394U-AL which I also own, can't even surpass a range of 5 feet beyond a stone wall. The culprit is its 433 MHz transmitter.
Setup was simple- you pop in two AA batteries into the receiver (which is smaller and lighter than the ones used by my other weather stations), and then do the same for the base. The base itself is pretty spartan but gives all the vital information such as indoor and outdoor temperature, time/date, plus it has an icon showing the forecast. I pretty much just set the time zone, and within half an hour it synced its clock with an atomic clock radio signal.
I definitely recommend this Weather Channel long range weather station. If you're in the market for one- get this or one that is 900 MHz/915 MHz. You'll save yourself a lot of frustration and wasted time and money.
