Bingfu 4G LTE MIMO SMA Antenna, 6dBi, Compatible with 4G LTE Wireless CPE Router, Cellular Gateway, Industrial IoT Router, MiFi Mobile Hotspot Modem, USB Dongle Adapter

I know it's inexpensive but I had 2 bars on my router (that this antenna is designed for) with the old antenna. Plugged in the Bingfu and only got an intermittent single bar.Totally useless

teleworking while moving between states, I found myself in need of serious bandwidth while on a crappy hotel wifi link. This, a cheap Netgear hotspot, and an expensive AT&T account got me set up nicely!

It honestly did nothing for my signal. I have a jetpack hotspot . I actually think it have me a less 9f a signal

Worse than nothing. Did not increase signal strength and in most adjustments actually made it worse.
