Manhole Antenna - New Design - Greatly Improved Performance

This antenna was designed specifically for use with sewer and overflow monitoring units. Sites where the telemetry is underground, and often covered with a metal manhole, need an easily installable but effective above ground antenna. After much experimenting and testing the Harvest team came up with the following solution.
