The Tri-Band Yagi (304411) is a super-effective high-gain antenna that works for just about every cellular frequency, including Sprint 4G WiMAX and Verizon 4G LTE. It isn't appropriate for everyone - it requires direct line of sight to the cell tower with no obstructions - but it works like a charm for users who fit those criteria:
Verizon tech informed me that I was too distant from the tower to receive a stable, strong signal. I have a clear unobstructed line of sight to the tower. The 3G store tech informed me I needed a Yagi Antenna, her advice was spot on. My signal is now strong and reliable and I am stoked.Wilson Tri-Band Yagi links:
I bought this antenna to improve my data service by enhancing a weak Verizon cell signal. Customer service advised expertly on the antenna cable requirements. The system works well out of the box, is simple to install and took me from 2 bars to a strong 4 on my MiFi.
Without an antenna, my AT&T Shockwave USB provided download speed of less than 1Mbps. I installed the Yagi antenna and a Cradlepoint MBR1000 router and now get between 3.5 and 4.2Mbps consistently. Way better than the 1.56 i got from Wild Blue satellite! Beyond my expectations.
