- About Us
Antenna Experts offer its PTM series pneumatic telescopic masts. Typical applications of these masts are for supporting small omni-directional antennas and log periodic antennas. A HF broadband dipole antenna can also be installed by using two similar masts. These masts are made of aluminum tubular section, which can be used for fixed or transportable applications. Their simplicity allows for ease of installation and transportation.
Our PTM series pneumatic telescopic masts and its diverse mounting options are essential pieces of equipment in the fields of sports analysis, lighting, photography and communications in particular, as well as military, police and fire departments. pneumatic telescopic mast are easily deployed in ten minutes by a single person, with the mast itself extended using either the integral hand/foot pump, separate stand pump or a 12 volt compressor.

All our PTM series pneumatic telescopic mast are made of 6063T6 ultra corrosion resistant, heat treated, architectural anodized aluminum alloy and is supplied with anodizing finish to protect it further from severe environmental conditions. Our PTM series pneumatic telescopic masts are suitable for installation on different surfaces like roof-top, concrete, soft/hard soil conditions. PTM series pneumatic telescopic mast are supplied with machine guides, locking collars and guy holders.
Each section of PTM series pneumatic telescopic mast are moves on Teflon bearing and high quality, high strength rubber seals. pneumatic telescopic mast once installed, can stay erected without air pressure. All the accessories like base plate, Spike anchor, foot pump, pegs/foundation bolts, hammer, stainless steel guy wire tensioner and clamps are supplied with pneumatic telescopic mast.
Extending between 11 meters (36 feet) and 21 meters (70 feet) in height, our pneumatic telescopic masts are available in different base tube diameter sizes: Ø101mm, Ø115m and Ø135mm. Each mast is constructed from 3mm anodized aluminium alloy, which is very robust yet more lightweight than steel.
PTM series masts are made of concentric sections of anodized aluminium, equipped with a lock against rotation. The top section is terminated with a large flange which allows installation of various payloads. The functional principle is the reverse of an air pump for your bicycle: if you put pressurized air into the nozzle of the pump, the handle extends due to the internal pressure.
Foot pump compressor required to extend the mast is included in the pneumatic mast shipment; but you can use any other existing compressor. Other compressor like 12 Volt which can be operated from vehicle battery with battery clip or cigarette lighter plug can also be supplied.
When one section of the mast is fully extended it locks into the next section. This locking ensures that the mast is held extended even when the pressurized air is removed. The mast can even be locked in different heights by not extending all sections. To lower the mast just pull the release handle on the lowest section, the upper section will lower themselves gently. Then pull the handle of the next section in reach, lower this, and so on...
Note #1: The anchor fasters are recommended where the pneumatic telescopic mast is required to install on the roof of the building or on concrete surface. The details of anchor fastener and image of anasterner is available in our technical datasheet which is available in .pdf format.
Note #2: The spike anchors are recommended where the pneumatic telescopic mast is required to install on the soft or hard soil surfaces. These spike anchors will replace the anchor fasteners. The details of spike anchors and image of spike anchor is available in our technical datasheet which is available in .pdf format.
Note #3: The pneumatic telescopic mast can also be supplied with non-metallic high strength guy wires. Normally these non-metallic guy wires are recommended for HF antenna installation. The details of non-metallic guy wire and image of guy wire is available in our technical datasheet which is available in .pdf format.
