Cobham Antenna Systems (Mastsystem Intl Oy)

Cobham Mast Systems designs all masts according to application specific requirements.

Full-scale simulated wind load tests are performed to verify mast specification compliance, when required. Wind load test facilities allow testing of masts with up to 50 m height.

Mast system deployment and service training is normally included in system deliveries. Mast maintenance and repair services in factory are available at request.

Cobham Mast Systems’ know-how and understanding of customers’ needs and requirements, together with material and manufacturing expertise, are based on more than 30 years of experience.  While Cobham Mast Systems has the industry’s widest range of standard, commercial off the shelf (COTS) composite masts, antenna pointing devices, and vehicle mounting systems available for rapid delivery, Cobham Mast Systems is also able to provide a custom, fully integrated solution precisely tailored to the application.

Cobham Mast Systems manufactures seven main product series: TM-, TR-, EX-, EXL- and EXB-masts, telescopic lifting poles and tripods including accessories for deployment. Masts are available from vehicle mounted unguyed masts to 50 m stand alone field masts. Every detail is designed for reliability and quick and safe operation.

Cobham Mast Systems’ telescopic masts have been used extensively around the world and have proven to be fully operational after long exposure to sand, dust, ice or snow.

EXB series of double drum driven telescopic masts are mechanical winch and belt operated masts. EXB series are designed for larger and heavier top loads for heights up to 14 meters with max. 110 kg top load. The mast can be used unguyed and used also for through-the-roof vehicle installations.

EXB series are made of glass fibre composite material with aluminium and stainless steel fittings. EXB-mast can also be made of carbon and glass fibre composite material at request. The masts can be supplemented with mounting kits for vehicles and shelters.

EXB series electric double drum driven masts are available with a hand crank as a back-up system for power failures. The tubes move inside each other on guide ways, which prevent the individual sections from rotating. Mechanical stops prevent over hoisting. EXB series are equipped with latch mechanism for controlling the raising order of the mast sections.

Lightweight telescopic EXL-masts are mechanical winch and belt-operated masts. EXL-masts are designed for larger and heavier top loads and are available in three sizes: EXL141 series is for heights 15-24 meters with a max. 55 kg top load, EXL167 series is for heights 15-30 meters with a max. 60 kg top load and EXL195 series for heights 20-50 meters with a max. 120 kg top load.

EXL-masts are made of carbon and glass fibre composite material. Masts are delivered with full field deployment accessory kits and they can be supplemented with a wide range of mounting kits for vehicles and shelters.

EXL-masts are deployed by two or three persons and are elevated with a hand-cranked winch or by an optional electric winch motor unit. The entire mast is rotatable by 360°.In EXL-masts sections open one by one and an automatic mechanical locking mechanism allows guying each lower section separately during winching up. This allows safe handling of higher top loads especially under windy conditions.

Lightweight telescopic EX-masts are mechanical winch and belt-operated masts. EX series is available in three sizes: EX105 series is for heights 8-15 meters with max. 20 kg top load, EX128 series for heights 10-18 meters with max. 40 kg top load and EX141 series is for heights 10-20 meters with max. 50 kg top load.

EX series are made of carbon and glass fibre composite material. The masts can be supplemented with a wide selection of mounting kits for vehicles and shelters.

EX series can be deployed by one to three persons and are elevated with a hand-cranked winch or by an optional electric winch power unit. The entire mast is rotatable by 360°.

TM series of light weight telescopic masts are push-up masts for heights up to 8 meters and for 2-5 kg top loads. Mast sections are pushed out and locked with friction locks one by one.TM-Masts are made of glass fibre composite material.
 
TM series are made of glass fibre.

Lightweight telescopic TR-masts are push-up masts for heights up to 12 meters and for 5-10 kg top loads. Mast sections are pushed out and locked in place with mechanical latches one by one.

TR-masts are made of glass fibre composite material.  The masts can be supplemented with a wide range of mounting kits for vehicles and shelters.

Lightweight telescopic TX-masts, a variant of TR-masts, are push-up masts for heights up to 7 meters and for a max. 25 kg top loads. TX-mast sections are pulled out horizontally to their full length and the mast is then lifted up in vertical position.

The company manufactures different ancillaries such as extension tubes, rotators, tilters, polarizers, winch power units, gin poles and mounting kits for vehicles and containers. We are also ready to design and manufacture different customer specific products to be included in delivered systems.
