Pre-Amp Placement
#1
I am new to the project having just completed assembling the Blue system.  I'm currently using ferrite antennas and still looking for optimal placement of it.  I have found that it works well in my attic and would like to leave it there for now.  I have built a PVC pipe enclosure for the ferrite antennas and pre-amp.  Pre-amp is, of course, connected to the blue controller in my home office via Cat6 cable.

My concern is the attic heat build up in the summer and the well being of the pre-amp in such heat.  Does anyone have any experience or knowledge of the long term ability of the pre-amp to function properly and survive in a hot attic?  I'm going to guess the attic will get to 120-140 F in mid summer.

Any advice appreciated.

I'm in the same situation. New unit online with my loops and preamp above the garage. It will get hot in there this summer. I'm hoping the preamp has enough tolerance with this kind of heat.

140F ~ 60C is no problem

Resurrecting an old thread.  I have the opposite question.  How much cold can the E-field pre-amp tolerate being that it has to be outside.  -20, -30..-40C?

According to datasheets all the IC's used on the H, operating temperature in free air is -40 to +125C.
That being said, I would not stress the board that much operating it at both extremes. You might start to experience solder joint failure due to uneven expansion and contraction of the various components.
