Mailbox Sensor on Brick Mailbox tip

I have installed 2 mailbox sensors on 2 different mailboxes at 2 different locations. I experienced poor connectivity between the bridge and the mailbox sensor. The connection was almost always poor and it was not uncommon to have the connection drop from time to time. I installed the mailbox sensor and antenna exactly as the instructions had indicated. I moved the bridge around to try and increase the signal. Nothing worked well. So, I drilled a hole through the back of the brick mailbox and mounted the external antenna on the back of the mailbox. The antenna now faces the house. I mounted the mailbox sensor onto the inside of the back of the mailbox so that it faces the inside of the mailbox door and connected to the antenna wire that I ran through the hole I drilled into the back of the mailbox. My signal when from poor to good.

I had to purchase a 1/2 inch masonry drill bit and drilled between the mortar. It took about 15-20 mins to drill the hole.

I believe the antenna aimed directly at the house, where the bridge is located, makes all of the difference in the world.

Just thought I would share my experience with others since I could not find any help or information on my particular issue with brick mailboxes.


Hi @DougPut. Thanks for sharing!

How long is the tether between the 2 sensor pieces?

The wire is about 12 inches between the motion detector and the antenna. More than enough to go through the mailbox and the brick.


Did putting the black tape on the antenna diminish the signal at all?
