The system is rated to the load stated. The end user is responsible for ensuring the loads are securely fastened. Rolatube Technology does not accept liability or provide warranty for usage deviating from the enclosed instructions.
- Before deploying the mast please read all warnings below.
- Avoid contact with heavy and sharp objects, in storage do not stack anything on top of Rolatubes.
- Do not use the mast if there is visible damage.
- The end user must assess the suitability of the pegs provided for the intended deployment environment, and replace with more suitable products if necessary.
- Rolatube mast systems are rated for wind speeds of up to 100kph (62mph). The maximum wind rating is based on the bare mast correctly deployed and guyed. The end user or system integrator is responsible for ensuring the system is safe with the top load mounted.
- Ensure the deployment site is clear of any cables or equipment that represents an electric shock hazard.
- Do not deploy near power lines, in thunderstorms or winds exceeding 100kph (62mph).
- Do not exceed the rated top load of the mast.
- Ensure any top load is securely fastened.
- Do not allow the mast to bend.
- Ensure the deployment site is clear of any underground hazards before using pegs.
- Ensure guy ropes and pegs are secure for duration of deployment.
- Consideration must be given to the location of any cable from the top load to avoid trip hazards.
- Consideration must be given when deploying in proximity to an aircraft landing site for aircraft movement.
- Rolatube masts are only designed to function in the vertical axis.
- Deploy the mast with the slot facing away from any prevailing wind.
Persons 2, 3 & 4 — At guy pegs: Maintaining tension during deployment to keep mast vertical.
Position Base Cap
Person 1: Place the base cap where the mast is to be deployed, with one peg hole facing into the wind. Secure with the red hard ground pegs.
Pace Out Guy Ropes
Persons 2, 3 & 4: Using the pegs in the base cap for guidance, pace out the position of the various guy ropes and insert pegs into the ground.
Connect Guy Ropes
Persons 2, 3 & 4: Unwind the mast guy ropes, connect to the pegs and lay the snap hooks next to the top cap, ready for connection as the mast is deployed. Wait at the 3 outer pegs.
Attach Top Cap, Guy Ropes & Hoist Rope
Person 1: Place mast between feet and attach the top cap with the flat edge aligned with the open slot in the mast, which is facing away from the wind. Connect the mast guy ropes and feed the antenna hoist rope through the clip on the top cap. Secure the hoist rope to prevent it being raised with the mast. Continue to unroll the mast vertically whilst Persons 2, 3 & 4 maintain light tension on the guy ropes to keep the mast vertical.
Slide into Base Cap
Person 1: When the mast is fully unrolled, slide it carefully into the base cap, whilst keeping it vertical and ensuring the slot is still facing away from the wind. Persons 2, 3 & 4: Maintain light tension on the mast guy ropes.
Secure Guy Ropes
Persons 2, 3 & 4: Tighten and secure the mast guy ropes. Do not overtighten.
Connect Balun to Resistor Tube
Connect the balun to the resistor tube using the snap hook.
Connect Antenna Dipoles
Unroll the antenna dipoles. Connect the antenna dipoles to the resistor tube and balun. Ensure all four strain relief snap hooks are correctly positioned.
Connect Hoist Rope & Radio Cable
Connect the hoist rope to the top of the resistor tube using the snap hook. Connect the radio cable to the balun and ensure its strain relief cable is attached to the snap hook on the tip of the balun.
Raise Antenna
Raise the antenna assembly using the hoist rope to the desired height. Secure the hoist rope to the base cap or ground using a peg.
Secure Dipoles
Use the pegs to secure the dipoles in position. If required, attach the extension guy ropes to the dipoles and peg and tension in the usual way.
