7-TR Tripod Positioner - ETS-Lindgren
7-TR Tripod Positioner

ETS-Lindgren's Model 7-TR Tripod is compatible with most ETS-Lindgren antennas. Users can be confident of accurate measurement results when using the 7-TR, which is constructed of non-metallic, non-reflective materials that will not distort measure data.

The 7-TR Tripod provides increased stability for physically large, ultra broadband antennas, such as ETS-Lindgren BiConiLog. Its unique design allows for quick assembly/disassembly and convenient storage. Quick height adjustment and locking wheels provide ease of use during testing. This tripod can bear up to a 13.5 kg (30.0 lb) load.

Three versions of this tripod are available: the 7-TR/POL Manual, the 7-TR/POL Pneumatic and the 7-TR/POL 3106.
