The signals from the satellites is itty bitty ( a radio technical term) here on earth and the signals from the Cell transmitters are humugus (another technical term). Even though the Cell transmitters and the GPS receivers are on different frequencies, the Cell transmitters also transmit harmonics of their primary frequency that may be in the same frequency range of the GPS receiver. The Cell harmonics are of a very low level compared to the primary Cell frequency, but are humugus when compared to the signal coming from the satellites. That close to the transmitters I'd be surprised if you were able to get a good 3D lock on the GPS. If the GPS was able to receive any satellites it may have only been giving you 2D information which does not include altitude. Just a though.... I enjoyed your blog. I just happened to stumble upon it. The problem with the GPS may have been from the Cellphone tower transmitters de-sensing the GPS receiver.

If they didn't, you're in much better shape than you've given yourself credit for.

Having a proper lightning rod on the top wouldn't be of much use as lightning is just as likely to hit it as the giant steel structure it's attached to and then arc out to the ground (either the last 1.5 feet to the dirt or maybe through the bolts in the concrete). The green wire however might be enough to dissipate any static buildup caused by the wind on the top of the mountain and/or keep any electrical potential between the tower and the fence at zero. Just a thought. I’m not exactly an electrical engineer (although I am an electrician of sorts) but on the subject of a ground wire, it might be for a slightly different purpose.

Kurama was bad, but that looks even worse - impressed that you made it to the top, though. I thought climbing Mt.
