Need4Speed, let us know how that goes. I was thinking about buying two myself, when I move the cell tower is going to be about 7.5 miles out from my location and its a highway tower so they might be pointed only at the highway but shall see.

Testing at my parents place was a complete success. Mounted the antenna pole about chest high just because it was easier. Top antenna was around 15' from ground second probably about 10'. Base test was WG3526/EM7565 with stock antennas. Got basically dial up speeds.

Basic stock antennas
There were 2 trees(a big maple and dense evergreen) we were pushing through in the yard and were able to go from about -105dbm to -95dbm. Also picked up 3CA. Wasn't able to grab any ss of the of the at!Gstatus =( was trying to explain everything to my pops. He's fully on board with getting my exact setup so ltefix definitely has another customer! His tv tower(40') is taller than mine(33') so he'll have no problem clearing the trees. Only drawback is he'll need some more expensive lmr600 vs my lmr400 since he'll need a longer run of cable. I'm already pushing it with my 50' runs. Here's the speed tests. I'll begin my permanent install tomorrow at my house.

That's called SUCCESS! Congratulations! :D And good luck at your place.

What is the last screenshot from? The one where it was only 4.64 Mbps down. Your test server was different then too.

Regarding coax cable, another option is powering the devices outside in weatherproof enclosures and then running ethernet cable from there to a router/wireless access point inside the house. Saves on money for the fancy coax and reduces line losses.

When you see the downloads drop down to the low 20+Mbps vs the upload staying the same, that generally means the tower is congested. More people are downloading than uploading, so the downloads are affected, but the uploads aren't affected as much.

Would love to see the signal stats and hear more about your aiming adventures! :D

Last screenshot is his current internet. Yes I noticed that it was a different server although i had Chicago favorited. I had them run speedtest on their direct wired computer too and the results were similar. I told him about the POE setup but he preferred to have everything indoors. We get some pretty nasty weather here. I do have a little more tweaking on my antenna mast before permanently installing... Gonna use my laser level to make sure both are perfectly lined up together. I'll post some pictures tomorrow of the setup.

This was an all day project! Just gotta tidy up some cables and bond my lighting arresters to the tower. I'll post up a more detailed tutorial on my setup sometime soon. I'll be doing this all again at my parents place soon I'm sure.

Here's my 4 gang junction box for lightning arresters, ethernet, and power. This took a while to build due to excessive ocd LoL

Here's it installed. Came out just as I'd hoped.

Now for the antennas themselves...

Locking in on tower didn't take too long since i pretty much knew exactly where tower is thanks to Google earth. Was challenging trying to twist the pole on the tower while watching my phone hahaha

Best i could get was -89-90 so I locked it in there.

Now if I could find a way better way on bridging the wg3526 and my asus at other end of the house I'll be happy!
Atm I'm using Jims work around. http://ltehacks.com/viewtopic.php?t=49

It's a bummer because i loose the wifi capabilities of the wg3526 at the other end of the house where the asus can't reach.

Congrats on the good results!

Something weird happened when you disconnected the second antenna. That wasn't just losing MIMO. Might want to try it again to see if those results repeat.

You have 20 MHz total bandwidth. Are there possibly other towers you can reach? They might have more bandwidth.

I do have another tower that's farther away (11 miles) and LOS isn't as good. I guess I could give that one a shot.

That is a different tower than your earlier tests. Look at the CID. Could be same tower and different transmitters, but the band is different too. If it is jumping between towers and the bands are mutually exclusive, you can lock out the band(s) of the one you don't want. You could lock out band 66 in this case, since you are only getting 10 MHz on this tower. That assumes band 66 is all you get. You want to grab stats while doing a download to see all the bands for carrier aggregation. The both antenna stats looks like there may have been some transmitting going on. If so, then that tower isn't as good for you as your earlier tower.

The speed test is what you want for the MIMO test. It is interesting that the signal strength for the primary antenna went down 5 points when the second was disconnected. But if there was a big enough time gap, other variables could have come into play.

Glad you pointed out the cell id. I did some looking on cellmapper today. Couldn't find any towers until I zoomed way out. The tower I'm locked on is one that is 19.2 miles away! :shock: I'm blown away by the speed I'm getting this far away! Averaging 50-60/25-30. What's even crazier is that the cell is pointed east on the tower and I'm northwest of the tower.

Time to climb the tower and do some re-aiming. Very glad to know i have almost 20 mile reach with these antennas. This opens up my tower choices a lot. Now to lock on the tower I was shooting for that's only 7 miles away.
