Product Details

This item has been discontinued

For our Canadian customers, the Wilson 8* series will soon run out of stock. Before being replaced by the Wilson 46* series, these products were unregulated by the FCC and IC, therefore, are more powerful than today's regulated boosters.

These legacy boosters are legal and grandfathered into program, and are in very limited supply.

Up to 50% off, 30-day money guarantee, and lifetime product tech support! For all clearance sales, check out our Canadian Clearance Page.

For US customers, please consider the Wilson 460102 Mobile 3G.

Wilson 801240 MobilePro Amplifier Only is an ingenious wireless booster with +45dB gain designed for both mobile and indoor use. This slim super-portable device can be easily moved from vehicle to vehicle and also your home, office or hotel room.  Its unique design actually incorporates an interior antenna right into the amplifier so you only need to plug it in and add an outside antenna.  This Dual-Band amplifier features a respectable 45 dB of gain and 1-watt of output power.

You can expect a coverage range of 2-8 feet from the unit, depending on outside signal, making this an ideal choice for vehicles, as well as desktop or small rooms, particularly when you need amplification for a laptop of PC data card.  In addition to A/C and D/C power options, this amplifier can also be powered via your computer's USB port.  The 801240 does not include the outside antenna so users can pick one to best suit their needs.  We also carry two hot-selling kits with this amplifier, the 801241 (with a 12-inch outside antenna), and the 801242 (with a 4-inch outside antenna).
