Remember those older AM/FM Portable Radios with the antenna that you extended by pulling it out? Or the Radio Antennas on older cars that would pop-out, extend and retract when you turned on the radio? This Mast isn't an Antenna, but it extends and retracts by hand in similar fashion.
Available in 20', 30', 40' and 50' heights. All ROHN telescoping masts are pre-galvanized and come assembled with hardware. Erection is made by simply connecting guys and brackets to the attached unique heavy duty rolled edge guy rings and clamps, extend each section one at a time (starting with the innermost section), insert the locking cotter pins, rotating the tubes to a locked position, and tightening the clamps. Repeat the process on each successive section until fully erect.
The unique ROHN Products design features interior tube flanging combined with a double crimped exterior tube to produce a stronger and more stable joint than most common masts. This design exclusive also prevents the sections from accidentally pulling apart and allows disassembly by pulling each section out through the lower end. Each section extends deeper in to the lower tubes than most other designs, adding still further to the stability of the structure.
This heavy duty series uses 1-1/4" 16 gauge galvanized tubing for top section. All other sections are 18 gauge.
