Hi @dsj David, On my first day of distance tests I managed the Sky 700m away to the hub inside the window. The next day using the Sky on the roof I extended the hub location Northwards from one headland to the next as far as practical to over 7km without requiring any extra antenna. Today I ventured Southwards and was unable to pick up a signal to the bare hub at over 12km. Great so now I had the opportunity to try adding a parabolic reflector to see if I could extend the distance without changing anything in the hub. Bingo I had it working about 12.4km away. Over 40,000ft or over 7 miles. RSSI was -93. So after I watched it working and doing its 3 sec updates for a few minutes I then removed the reflector to check its effect, and it lost reception. The Hub was held at the focal point of the reflector by rubber bands. ![48%20PM](https://us1.discourse-cdn.com/flex020/uploads/sws/original/2X/5/534314dbe087ce9c8b5188c42e1706e2e383f83e.png) The reflector aimed at the Sky on the headland: ![24%20PM](https://us1.discourse-cdn.com/flex020/uploads/sws/original/2X/7/72b1c0ef1b5bd4151a584002ec0af24defdd84d9.png) The Sky is on a pole at the North East or top right of this picture and the hub is at the headland in the South West or lower left of this map ![10%20PM](https://us1.discourse-cdn.com/flex020/uploads/sws/original/2X/3/3ac393f7f8646d6815609b79248dabd352fecf6a.jpeg) This is the Australian frequency hub to a Sky running at 3.33 volts. cheers Ian 🙂 --- _[View the full topic](https://community.tempest.earth/t/sky-maximum-distance-from-hub/3292)._
