Power infrastructure on temporary scaffold at KREW P301 ~1 kW Solar array 15 foot tall Footings in soil/rock

Current Site Location P301 tower in Kings River Experimental Watershed Proposed Tower Locations Soaproot Saddle Tower: 37° 1'51.85"N 119°15'23.15"W Courtwright Tower: 37° 3'59.75"N 118°59'18.51"W Instrumentation will provide an elevation transect from the rain dominated to snow dominated hydrologic regimes in Southern Sierra Nevada

The Heavy-Duty aluminum crank-up towers are designed to accommodate antennas with large wind surface areas up to 18sq.ft. and 125 lbs. of dead weight. These models will accommodate a large variety of commercially available rotors and a universal rotor plate is welded in place. This will allow a beam or other directional type antenna to be oriented. Telescoping towers are complete with a heavy duty 2” dia. X.125 wall x 8 ft. long mast, guy ears on each section, heavy-duty building bracket and tilt base. Model T-100H Approx Extended Height: 120 feet Weight: 400 lbs Temporary base and Telescoping Tower Specifications Power infrastructure similar to current P301 Tower. Tower will be T-120H or smaller
