FlightAware Feeder/USB stick

Hello,

I am trying to find ways to get my antenna higher. It is current mounted outside and I have options to go higher with it but the cable length of course is my issue. One way would be able to place the usb dongle in my attic. However, I notice it already runs pretty warm inside my house and I am afraid it will get to hot in the attic. Does anyone else have their equipment in the attic?
