Fantastic thread!

QQ: did you notice any changes with the band / high pass filters installed on the LTE side ?
Not really, if there was any changes they were minimal.

This is my rig on the back patio. Signals inside of my house were never better than one bar, with two to occasional three bars outside.

With the antennas and a Mofi4500 i now have 30down and 25up with signal strength -88dbi. Tower is five miles away. The 10db 2.4ghz antennas cut right through the house and give me excellent performance from inside the house.

The flat panels actually have better performance in this config than in the -+45 offset. Additionally, subtle angle change to the second panel helped to strengthen the alternate signal.

Excellent thread!! I learned a ton and now have amamazing speeds

I’m 6-9 miles with hardly any LOS, will this work?

No idea without you actually trying. The situation is different for every user.

There are users though that use these high gain antennas to connect to towers over 5+ miles away with no issue.

Swifty you sound like the man with the plan.
I having some pretty painful issues. still learning cellular world.
So I have a mofi 4500 V2 router, 2 WirEng wide band antennas(dont worry i didnt pay for them), and using ULLM240 cable, 25ft. I will probably shorten.
So I just purchased 2 new antennas and mounted them in place of the WirEng because they are supposed to have higher gain, 16dbi. They are put in vertically, one over the other, about 1 ft apart. My signal did improve by 8 to 95 db. but my speeds are still the same. here is a link of my antennas:

New Antennas

Am I cutting myself short in being able to pickup better speeds?
speeds are around 10Mbps and randomly a few times a day i will pickup 25Mbps from my scheduled tests.
Still learning about mimo tech.

Could be hurting yourself with the LM240, personally wouldn't use it for anything over 10 feet. I have a 25 ft run and using LMR400.

Also depending on the band, loading and distance you may not be able to do any better. Since you are seeing some higher peaks at times it may just be a case of band congestion.

Just my opinion for what it is worth. Good luck!

LMR400 could make a difference. The only way to know for sure is to test with your modem connected to the 25ft of the LMR240, then connect your modem to the antennas with a short jumper and compare. I'd do this within about 3-5 mins to give you an idea of if it is the long cable run, or congestion that is the issue.

Sorry about the delay, didnt get an email that you responded.
On my initial testing i was using a 3 ft pigtail at the antennas before adding the longer 240 cables, and speeds were at the higher range, 22-24 but I didnt stay up there long to check stability. I also ended up trying a suggestion from another user to mix up the antennas, one band 12 and one wide band, getting more stable speeds between 20-30Mbps along with CA. Cant seem to get Band 2 as primary, its 20Mhz bandwidth. I am going to test out the shorter cable with this setup in the next few days.

I also ordered materials and parts to mount the module and router at the pole. I ordered a Raspberry Pi 4 bc it has gigabit Ethernet, though i wont see these speeds, it will help with data rate transfer.
I am tossing around the idea of either using openWRT or just configuring a linux distro to manage network services.

Since I have a veteran on the line, I am expanding this project to include dual LTE services for internet and intend on load balancing them. will try to check back later in the week when I get it all together and share pictures. I will pulling the module out of the Mofi router. going to trash their firmware, they have to responded to me in weeks for help. BTW, to you know the version of openwrt or ROOter i should use for the Mofi4500 V2? might use it for training on the setup. Is Pi 4 supported in ROOter? cant seem to get any responses from their forum as its just a huge thread. Id offer host server space if I could get someone to talk to me and help make things a bit more organized.

Any suggestions on running a linux distro and packages to manage the network connection on raspberry? The reason I ask, is because I can add sensors to the pi and be able to manage better, and looking to move it up 60 ft in a tree and can not check on it easily.

anyways, thanks for the response and any help is appreciated.
