ExtAnt&trade; for Verizon MHS291LVW External Antenna Adapter (EXTANT-VZW-MHS291LVW) The ExtAnt&trade; is an indispensable adapter needed to connect your Verizon MHS291LVW to an external antenna to greatly enhance your Verizon MHS291LVW performance in low-signal situations (external antenna and coaxial cable not included). The ExtAnt&trade; can also be used to connect your Verizon MHS291LVW to a direct-connect booster/amplifier (but in such case you will need to make sure that such booster/amplifier supports all bands your Verizon MHS291LVW operates onto). Do not use the ExtAnt&trade; with wireless boosters/amplifiers/repeaters as a direct connection to such devices may damage both equipments. We recommend that before purchasing the ExtAnt&trade; you verify that your Verizon MHS291LVW does have an external antenna connector for the WWAN/Cellular signal. Do not purchase the ExtAnt&trade; unless you see such connector. If your device has a second antenna port for MIMO, then you will need to purchase two of these adapters. If your Verizon MHS291LVW has a diversity or aux RF feature, then a second adapter is optional. The ExtAnt&trade; operating frequency range is DC-5200 MHz. This external antenna adapter is made for the Verizon MHS291LVW (SKU EXTANT-VZW-MHS291LVW). For MIMO devices, we recommend that you purchase two of these adapters, as a MIMO signal is split into two equal and necessary parts.
