Telescopic Towers – Guyed andUnguyed
Aluma proudly offers aluminum guyed and unguyed towers as an efficient solution to meet any of your ham radio, HF, or UHF/VHF requirements. The lower section can be bracketed to a suitable structure rather than guyed, ensuring solid lateral support for your tower.
We offer two, three, and four section towers, comprised of telescoping sections, rising to 30 – 100 feet. Our ham radio crank up tower models are constructed of extruded6061-T6 tubing, both lightweight and strong. Tower sections are manually welded by certified welders using the TIG (Tungsten Inert Gas) welding process. All towers are rigged to allow the sections to telescope simultaneously, using stainless steel cable and pulleys. Aluma towers are designed according to the TIA-222-G Structural Standard for antenna supporting structures and antennas.
Aluma includes the following standard features with your tower:
- Tilting base: either our unique H-type hinge base or T-type tilt base (fixed base can be substituted at no charge)For permanent applications, the tower base is attached to a concrete pad. For temporary applications, an optional temporary base is available for quick, short-term deployment,such as field day, emergency operations, or mountain-top operation.
- Aluma’s engineered building brackets provide six inches of standoff for attachment to a suitable structure (house, barn, shed, etc.) against one side of the tower (custom brackets are available for an extra fee)
- All tower hardware, including stainless steel rigging, and cables and pulleys
- Zinc-plated hand crank worm gear winch (electric winches, both DC and AC, are available)
- Welded aluminum guy ears at the top of each section, color-coded to Aluma’s guy wire systems (guy wires sold separately)
- Aluminum masts for easy attachment of antennas or instrumentation
- Safety stop latch to remove tension on cables and eliminate unwanted retraction
- Updated aluminum rollers to facilitate smooth extension and retraction
Tower options range from:
- Standard Duty HN
- Extra Heavy-Duty Towers XHD
- Extra-Extra Heavy-Duty XXHD
Standard Duty HN
18 sf wind load 125 lb of payload 70 mph
Standard Duty Models for Amateur Radio applications:T-50HN; T-75HN;T-100HN
The HN series is designed to accommodate antennas with large wind surface areas of up to 18 sq. ft (1.6723 m²) and 125 lb (56 kg) of maximum payload capacity. They are tested with these loads at wind speeds of 70 mph (112.65 kph). Payload is equal to the total weight of the antenna(s), rotator, and the mast.
These models are equipped with a universal rotor plate welded in place to accommodate a large variety of commercially available rotors, Hygain (up to Ham IV) and the Yaesu 800-1000, enabling the orientation of a beam or other directional type antenna. All tower packages include a heavy-duty 8 ft (2.4384 m) mast 2 in (5.0800 cm) diameter and 1/8 in (0.31750 cm) wall, guy ears on each section, an engineered building bracket, and tilt base which allows tower tilt over to ground level.
The “N” indicator on model numbers denotes the capacity of the tower to be fully nested when a rotor is installed on the top section. This is a special feature only available for Amateur Radio models.

Tower Mounting Solutions
Aluma towers can be installed on a building utilizing our building bracket, but they can also be installed in open areas with or without the use of concrete. Our innovative mount solutions allow the towers to support the same payload capacity regardless.
Mounting Pole (MP-2) Direct Ground Mount – no concrete
The MP-2 Mounting Pole allows the customer to install an Aluma tower without a concrete pad. This eliminates the need for bracketing the tower to an existing structure. The installation requires only a 6 ft deep hole and locally available dirt and gravel. It uses water to compact the soil and stabilize the system. Aluma has hundreds of current customers utilizing this system, including NASA and U.S. military forces.
The MP-2, made of scheduled 40 galvanized steel, has a top-pivot at six feet that allows the user to tilt the tower from vertical to horizontal positions, eliminating the need for climbers or riggers. The standard pole is available with a hand crank winch and the MP-2 can be easily upgraded to an electrical system (AC or DC) on the tilting and hosting systems.
The MP-2 is constructed with hot-dip galvanized steel and weighs approximately 230 lb. It is capable of supporting the standard Aluma Tower models, guyed or unguyed (HD, XHD & XXHD).

|Tower Model||Aluma Part No. (Tower +MP-2)|
This new Independent Base design allows the customer to mount any Aluma tower to an existing three-foot concrete pad, eliminating the need for bracketing the tower to an existing structure.
Not only can the Independent Base fit in multiple existing concrete pad configurations, it also allows the user to tilt the tower from vertical to horizontal eliminating the need for climbers or riggers. The standard model is available with a hand crank winch that can be easily upgraded to an electrical system (AC or DC) on the tilting and hosting systems.
The Independent Base is constructed with structural steel, has a powder-coated finish and weighs approximately 350 lb. It is capable of supporting standard Aluma tower models.

Medium Duty Trailer/ Tower Systems
The TM-12 small mobile tower system is available with a wide variety of options and accessories and is highly suited for meteorological work, test data acquisition, and many other tasks where a small portable tower is tantamount. It’s similar in size to a personal watercraft trailer with a very different design, of course. These small but hearty mobile trailer towers are constructed of tubular structural steel before being hot-dip galvanized. They include our A-frame tongue design with an additional T-bar for added structural integrity. It complies withDOT Federal Motor Carrier Safety Regulationsand will pass licensing in all 50 states.
Capabilities of the TM-12:
- The deck of the mobile tower unit is about 4 ft wide x 16 ft long and will accommodate a small equipment cabinet.
- Available accessories for a complete mobile trailer tower solution include an Aluma Tower coax reel, spare tire, antenna storage tubes, and portable generators.
- Available tower options include most models, in either 35 ft (2-17 ft sections) or 50 ft (3-17 ft sections) heights on this mobile tower unit.
- It is extremely lightweight and easily transportable by most vehicles with a suitable trailer hitch.
- The TM-12 can fit into a transport container.
- For a list of the complete specifications please see the table below or feel free tocontact usto discuss all of your small mobile tower or mobile trailer tower requirements.
