Extending Range Of Wireless Flow Meter

I have a flow meter that is already installed in a box no more than 6" below ground level. It keeps periodically losing signal and disconnecting from the controller. It’s about 70’ away but it’s down a hill slightly so I think it’s having a hard time seeing the controller signal over embankment.

I really don’t want to pull it out of the box and re-plum the irrigation line. Anyone have any suggestions how I could get 5-10dB boost on the signal hacking the unit or adding a small antenna? Because the unit is in the box I’m tempted to remove it and try to take it apart and somehow tap into the antenna and install one outside of the box.

Any suggestions would be much appreciated!

I don’t know if I should share this, but here it goes :wink:


Thanks for the info, not sure how I missed this thread! I tried the wire taped to the face of the unit and no dice…now my other controller that was fine has lost connectivity once I placed the lid on the box. This is really disappointing. Now I have two paperweights in my vineyard until I can try to find an antenna based solution. Really bummed out. I’ll try the cantenna but I’m not hopeful. Can your engineers at least recommend an aftermarket product that I can try? I’m willing to spend a bit more to get these to work, I just can’t remove them from the irrigation system now that they are in.
