Hi Tony, look in the forum for information regarding the installation of the boltek http://discourse.weather-watch.com/t/10461 this is one of them, there are more issues in other posts, it’s just something that you have to fiddle with to get it working right. I had mine relocated 3 times. It can be installed inside or outside (the antenna) from there on it’s just a matter how good the reception is and how accurate. No limit in the distance between stations.
