LB1120 Antenna

[jmbones]

What is the difference between the main port and the "div" port? Do both need to be used?

Anyone have a successful setup with external antennas and 25' run of coax cable to the LB2120 in your house? Care to elaborate on your up/down speeds and what equipment you're using?

Thanks!

An Rx-diversity antenna is used to resist the fall of signals caused by high-speed movement and multipath effect. Basically, it improves the receiving signal quality and the antenna.  There is no difference which connector you use if you're plugging in a single LTE antenna with two TS9 connectors.

I'm using an external on my LB2120 (which is in my basement and has a two-bar signal).  But it's only a 2 meter cable.  I would imagine (but won't be able to confirm) that signal attenuation over the long distance you mention might negate any gain you would get from the antenna.  Basically, it would degrade by the time it made it to the router:  https://www.electronics-notes.com/articles/antennas-propagation/rf-feeders-transmission-lines/coaxia...

All that being said, I'm getting decent 50Mbps downloads with the antenna I got:  https://smile.amazon.com/gp/product/B07YDHM8KF
