Submersible Double Depth Antenna (SDDA) - Underwater cable locating

Submersible Antenna for Underwater Locating The submersible, double depth antenna is suitable for use under water for tracing pipes or cables. Submersible Double Depth Antenna is an accessory designed to work with Radiodetection Precision locator fitted with accessory socket.

It work as an extended antenna separated from the locator to detect area where a standard locator cannot reach. Tracing buried pipes and cables across waterways and estuaries are frequent and critical locating applications.

Less frequent but equally important is tracing and locating lines between the mainland and offshore islands. Application of submersible antenna When locating pipes and cables the locator sensing antennas should be as close as possible to the target line so it is not practical to locate lines buried under a river or seabed from the surface.

In most cases, it is necessary to measure the depth of cover to ensure the line is protected from dragging anchors or other underwater hazards. There is a weight at the bottom of the antenna to provide the stability.

The 10m of submersible marine umbilical cable is the standard, but lengths of up to 100m can be supplied. The extra length enables the antenna to be carried by a diver on a riverbed or seabed while the locator is used in a surface vessel.

It is crucial to have effective communication between the operator with the locator and the diver with the antenna. Alternatively, the antenna can be fastened to the end of a non-metallic boom from a b
