Thanks for your add on as it truly is a total fix for the
problem. As we all know when all components of a system are
grounded to a central point they all rise and fall in potential together
and eliminates or minimizes damage.<br><br>
The more we hear about grounding solutions should make all aware of its
definite benefits.<br><br>
Thanks again for your input to the digest; this is really important to
optimizing the performance of the Networks.<br><br>
Best Regards,<br><br>

Adding onto Neil Ziegelman's comments regarding the 130 GPS...<br><br>
On a portable deployment of several solar-powered stations a few months
ago, we had lots of trouble with GPSs flaking out with this static
problem. We would experience long periods of malfunction; sometimes
they start working on their own, sometimes just visiting the site would
fix it (presumably by touching it and discharging it). On a hunch,
I figured it might be a static issue and blamed it on a poor
ground. Installing a copper grounding rod (connected to the
negative terminal on the system battery) instantly and permanently fixed
the problem. The GPS then seems to get a good ground through the
130.<br><br>
