  1. For those of us who use cellular broadband for Internet access, I thought I'd pass along a method I've recently added to our motorhome to give us better signal quality, for both broadband and voice cell phone service. In many places we've been while traveling, especially in the west we had a lot of trouble getting good cell signals. My first method was to add an external Wilson Trucker antenna. In some places this is all that was needed. In others it made little difference. In one location where we spend a lot of our winters, we had extremely poor coverage, even with the Wilson antenna. So I purchased a Wilson Dual Amplifier Kit that came with an indoor and an outdoor antenna along with coax cable to connect things together. This particular amplifier is a two-way amp that picks up the outdoor signals thru the external antenna and re-amplifies the weaker signal inside the motorhome. Likewise, the indoor antenna picks up the signal inside the motorhome from the cell phone and/or broadband modem card and the amplifier re-transmits it at a stronger signal to the outside antenna. Another advantage is it also works with any cell phone so you don't need an external antenna connector on your phone in order to connect it to an external antenna. I've been able to boost the signal strength from having no signal to barely one bar to three and even four bars. It even works well outside the motorhome while sitting on the patio. The internal antenna is a flat square panel antenna about 7-inches square and 2-inches thick. It's designed to be mounted on a wall or ceiling, i.e, flat surface. It has a coax connector on one side. The external antenna is your choice of Wilson RV Antenna, Wilson Trucker Antenna or a high gain directional yagi antenna. The antenna's need to be mounted at least 20 feet apart so they won't interfere with each other, which can cause the amp to shut itself down. But at the same time you can't add to long of a coax run because of the loss of signal inherent at these super high frequencies. I actually did add a 10-foot extension cable to mine so I could get the separation necessary. The most difficult part of the installation is routing the cable so it's not just laying along the floor of the coach. I routed mine down through the floor and inside the basement area from one end of the coach to the other. The cost of the kit I purchased was $389. There is a different kit for a smaller environment that costs about $299. I didn't feel the smaller environment kit would work well enough for me.
