MIMO Setup Help

[Twoods196]

Hello all, I've got my we826 and mc7455 all hooked up and getting a signal with the stock antennas but I had ordered at the same time 2 wide band directional antennas from The Wireless Haven these to be exact. https://thewirelesshaven.com/shop/antennas/700-27 ... al-antenna

Now my question is concerning the postioning of the antennas. I know I will need to set them up in a diamond shape so there polarity basically makes a X kinda but my question is to the placement of the second antenna to the first one. How far below the first antenna is ideal? An should they both be aligned the same or should the second antenna offset to the side some kinda so the 2 V tops come down beside each other. Hopefully I explained that well and someone could help me out with this. It would be greatly appreciated!

There are a number of people that have tried various arrangements and spacing.

Some mount the antennas side by side using a T on the top of the mask which seem to work better in heavy foliage.

Most install them one on top of the other with only an inch or two between. This seems to be a general default for the configuration.

Other customers have experimented with the spacing between the antennas, and most admit it makes little (if any) difference in their performance. Others say that spreading them with a six in space improves their Signal to noise ratio.

This is really heavily dependent upon your situation, and you'll have to experiment to find the best positioning.

That being said, wireless channel conditions can change from min to min, and hour to hour, so don't get too obsessive over it, just make sure that the signal stats on both antennas look equal, and leave them there.

Thanks for the replies. So as for alignment the point on the bottom of the top antenna and the point on the top of the bottom antenna should be aligned? As most picstures I have see the bottom antenna off sets the top one and then slides up beside it by a inch or two. Which way would be best for someone that lives in North MS. Whave some hills but nothing major and we do have a lot of foilage. Thanks!

Nevermind as I was setting it up I see now why there offset. So the bracket can attach to the poke. Thanks again

You want to align them in a +/- 45 degree setup.

The antennas should indicate on a sticker the direction of polarization, and you want one at -45 degrees and the other at +45 degrees.

I am about to install a pair of Wilson 314411 Yagis... I see that they have Arrows pointing towards "polarization". I called Wilson to ask if the arrows should be pointing at each other at a 45 deg angle they said that they recommend mounting them vertically. So this begs the question... is the 45 degrees offset a best practice? and if so does anyone have experience with what direction the arrows should be pointing? (towards each other, away from each other, or in the same direction)

I am planning on mounting them on a vertical pole, any challenges here? I have seen several examples of mounting vertically as well as horizontally but have not seen any pro/con info on the forum.

As a side note, the weeping hole would probably need to be closed up and drilled on the opposite side if arrows are pointing toward each other.

I dont believe that it matters which end is on top, so likely keep the weep holes facing down. I believe the the angles used are an attempt to match the plane of the carrier equipment of the tower your using. Common practice seems to be 45 degrees from vertical plane. One tilted "left", the other "right".

Im no expert though, maybe someone else can explain further.

I was wondering what the heck is a "weep" hole on the antenna housing?
Is it a hole to drain moisture condensation?
Teach an old dog here some new tricks please, he-he

[Didneywhorl]

Bill, you are correct.

[BillA]

Well, I'm always right, even when I'm wrong. ha-ha just kidding
So unless gravity reverses on Earth, the weep hole should always be facing down, to shed its tears while weeping. ;P
