Harvest Manhole Antenna

Tough antenna designed for use on manhole lids even in heavy vehicle traffic locations. This antenna was initially designed for use with sewer and overflow monitoring units - sites where the telemetry is underground, and often covered with a steel manhole lid where you need an easy to install but effective above ground antenna. After several years experimenting and testing the Harvest team came up with the Manhole Antenna. They are sold worldwide and are the easiest to install manhole antennas. They have found other applications such as on the top of roadside cabinets where the customer required extremely vandal resistant antennas.
