WiFiX 1.7-3.8GHz 2x MIMO Parabolic Grid Antenna

After trying out some other flat panels from several sources/vendors, I thought I'd try the parabolic grid 2x MIMO antenna from netsolution.shop (thewirelesshaven.com).

What stands out in the specs is an impressive a 21dBi gain from 1710-2690MHz:

For my specific application, the placement is less than ideal (attic in a 3 level house, wall facing target tower). It replaces two Wilson 314453's I am using in the same location with a MOFI4500 w/an AT&T MVNO (Ubifi.net). It is attached using two 8' LMR 400 cables (N male to SMA male). The Wilson's were attached using 4' LMR 400 cables.

Specs on the Wilsons:
  • Frequency range: 700-800 / 824-894 / 880-960 / 1710-1880 / 1850-1990 / 2110-2500 MHz
  • Antenna gain: 5.2 / 4.4 / 4.2 / 10 / 10.6 / 8.2 dBi
  • Beamwidth: 70° horizontal, 50° / 45° vertical
  • Polarization: Vertical
From the above info, it can be inferred the parabolic grid is a significant upgrade over the Wilsons, albeit at more narrow spectrum of frequencies.

The result? It's good--it's VERY good. From the testing device (MOFI4500), an approximate improvement of 8dBm was acheived (data below). Most importantly, the placement and aiming of the parabolic grid was simple in comparison to the Wilson's (about an hour vs. approximately 4-6 hours).

As compared to the Poynting XPOL-2-5G antenna (2x MIMO flatpanel), currently mounted outside(rated at 11dBi gain), the parabolic grid outperforms it in all respects, even while being mounted in the attic. NOTE: The 5 meters (16.4 feet) of LMR 200 cable that the Poynting was optioned with likely did not help it.

Specs on the Poynting XPOL-2-5G:

What do you think of the quality of the dish itself?

Wow thanks for sharing these results. Impressive.

I assume the roof was something like wood shingles and not, for example, metal?

If this antenna covered the bands I need this one would be a contender.

This would cover band 66 which seems to be where my devices gravitate to in both Tmobile and ATT. So that’s promising!

But the range from 600-800 is the other place they sometimes play, and this appears to bypass all that. So I’d be largely giving up any hope of Tmobile 5G reception I’d guess.

Im not seeing that unit. Was it a special order? How much. My +15 flat mimo antenna didnt help much.

It was available from The Wireless Haven for a short period of time. Might be coming back. Not sure when.

Here is the listing for that antenna, from when they stocked them : https://thewirelesshaven.com/shop/anten ... d-antenna/

Have used one like this
https://www.ebay.com/itm/234011223567?s ... 1438.l2649
It has similar Gain but has different Frequency spectrum.
Used it mounted to a WiFi square looking grid.
Possibly could sell one since the store if out of stock and people around me have gotten fiber.
If anyone is interest.
