Two quick questions about antennas. I have an LB1120 modem, first question; can I attach two antennas or just one? second question, if I can only attach one, do I need to use both TS9 connectors? Thank you

Hello clydeml You can purchase an external multiple input, multiple output (MIMO) antenna for the modem to extend the mobile broadband signal range indoors or in fringe network areas. The external antenna plugs into the two antenna connectors on the modem to boost speeds and extend coverage in buildings or vehicles, or in remote sites where network coverage is sparse.You could, for example, attach the external antenna on a window with a suction cup.

I'd love to see a sticky thread of some sort on this issue. I've been doing a LOT of searching for a QUALITY MIMO antenna for the LB1120 and I have not come up with much so far. The Netgear branded antenna for the LB1120 is not getting great review on Amazon I'm sorry to say.

I ordered two of these (Yagi Directional Roof Antenna 3G/4G/LTE Wide Band 9dBi 800MHz-960MHz and 1.7GHz-2.5GHz Dual Range - Cell Phone Signal Booster Log Periodic Cellular Antenna- TP514) on Amazon. Mount one at 45 degrees and one at 135 degrees. I am in an area where cell phone service is very spotty, but this configuration mounted about 20 feet above ground gives me a solid 4 bars. Cabling is the trick. Pay close attention to the center pins on both male and female ends. there does not seem to be a siongle standard for the center pin, sometimes they are male, sometimes female. I wound up using two of these (TRENDnet Low Loss Reverse SMA Female to N-Type Male Weatherproof Connector Cable (8M, 26.2ft.) TEW-L208) with this (2pcs SMA-TS9 Adapter SMA Female to TS9 Male with Stainless Steel Material). Hope this helps.

Thanks very much for the very informative reply. I like the approach you took and it seems very cost effective compared to what I have seen. My only worry is that I need Band 12 (B12) support. The LB1120 supports it and it's on the 700 MHz spectrum. Did you use off the shelf mounting hardware to get the proper mounting angles? If so, would you mind posting part numbers? Thanks again for the great post.
