Resideo Technologies recently released a technical notification (TN #69) outlining an issue with the CELL-ANT3DB External Antenna kits. It seems that for some time, these kits have included an incorrect mounting bracket. Without the correct mounting bracket, proper mounting is not possible.
The Resideo CELL-ANT3DB External Antenna kit is an outdoor rated antenna kit that supports a number of different cellular frequency bands. In addition to simply moving the antenna from the mounting location of the radio to a location outside, the CELL-ANT3DB also provides up to 3dB of signal gain to improve cellular reception for the AlarmNet communicator.
To resolve this issue, Resideo has released the technical notice listed here. All current stock has been called back and reworked to have the incorrect bracket replaced with the correct one. If you are purchasing a new CELL-ANT3DB, you can check the barcode sticker on the box. If there is a Green Dot on this sticker, the product has been through the rework process and has the correct bracket.

If you recently purchased a CELL-ANT3DB from Alarm Grid and you believe your product has the incorrect bracket, contact us at email@example.com and we will verify whether your product is affected, and will arrange to have the correct bracket shipped to you if it is. The information in the technical notice is lacking a bit, so in addition we've contacted the product manager to see if we can get some more data on either date codes affected, or images that show us what the incorrect bracket looks like, as opposed to the correct bracket. We will update this post with more information when/if it becomes available.
We heard from Resideo today that this issue affects a very small number of units. This error occurred on only three (3) days of production. Date codes E215, E222, and E223 are the affected production days. You can see the date code in the image above. It shows E256. If you purchase a CELL-ANT3DB Kit with one of the affected date codes, and the box has the green circle sticker mentioned and shown above, then your product is good to go. If you purchase a product with date code E256 or later, whether it has a green dot or not, the product is also good. If you purchase a product with date code E215, E222, or E223, and it does not have the green dot sticker, then you need to request a replacement mounting bracket.
