Bob,
I wonder what would happen to your cell service if you had an auxillary antenna on the roof - 3g store (and I am sure others) offers several antenna options. I was looking at one that is a wireless proximity boost for a regular cell phone - you just need to be close to it to benefit.
They also have options for my Sierra Wirelss modem with various size antennas with built in grounding plane so that they can easily be attached to a MH mirror or ladder - and a model that attaches through the MH roof... these plug directly in to the wireless modem.
It says that they really kick up a signal - your cell phone may be getting 0 to 1 bars and the modem on the antenna could be getting 3 to 5
I would like to ask the list if anyone has had experience with these antennas, how they work, what type or model is best, any advise regarding where best to buy them, best way to install on a MH and surge/lightning protection - how do you ground a surge protector on an MH without a copper rod pounded in to the ground... or do you even need one anywy.
