After studying a number of great posts here, I decided to try installing my piAware in my attic. There is an AC outlet handy and also a roof vent with some tiny perforations in the side that is easily accessibly. So I placed my inexpensive antenna inside that. Based on this first day of operation I think it is working pretty well. I’m getting consistent reports from planes as far as 200nm away and well distributed around the compass. Some in the 200-250nm range. I’m in the Dallas area and can see planes as far north as Tulsa and Fort Smith and nearly as far south as Austin and Houston. I think that’s great for an $8 antenna.
I am a bit worried though about the power source. The attic temperature never gets that cold (water heaters and central heat is in the attic). But in the summer it can be a seriously unpleasant place to be (Texas). The power adapter I am using does not have any temperature or humidity limitations on the label, though it is overall a high quality adapter.
Am I paranoid to worry about a major failure due to heat/humidity (like a fire)? Is there a USB power adapter that would be spec’d for this (or are all the UL adapters spec’d for this)?
If anyone is curious, I bought one of these antennas. https://www.amazon.com/gp/product/B013S8B234/ref=oh_aui_detailpage_o01_s00?ie=UTF8&psc=1. Once I decide where to leave the piAware give building my own a try.
