Description
Sectionalized aluminum antenna masts/towers, lattice construction
MAL3000, MAL4500 and MAL 6000 (upgraded to 6m) are solid, lightweight aluminum construction antenna towers with the possibility of climbing by a qualified installer. Guy-wires are not necessary which makes the mast require little space and has a beneficial effect on aesthetics. Guy wires are required for heavier antennas and higher 6m tower. The mast stands on the tilting base fixed on a ground with three anchors, cemented into the ground. The masts are suitable for lightweight antennas such as WLAN, STL or wire antennas and with guy wires at several levels also light FM or TV broadcasting antennas. It is essential to be conservative when it comes to safety! The mast is designed for small wind loading antennas in the first wind zone.
Height of the mast: | 3m, 4.5m or 6m |
Number of sections: | 2-3-4 |
Wall thickness: | 1.5 mm |
Material: | Aluminum |
Construction: | Framework structure of triangular cross-section : 250 x 250 x 250 mm |
Supporting pillars: | Aluminum tube Ø 35 mm |
Main features: | • The lack of guy-wires (we recommend using them!) • Tilting base application enables lowering the mast • Possibility of climbing the assembled mast by the person + antenna weighing up to 100 kgs with winds up to 5 m/s (at your own responsibility, exercise extreme caution!) • The possibility of transport in the trunk of a passenger car since sections are only 1,5m • The dimensions of the product after packing enable to send it by courier across Europe easily |
Weight: | • 15.15 kg – Mast (3 sections, 20Kg 4 sections) • 3.01 kg – Mast base • 1.6 kg – Anchor for concrete |

Non-included optional Guy-wires set for 1st/2nd/3rd level (This is not included, you have to add it manually)
A set of guy-wires for multi-element structures made of 1.5m sections.
Kit contents:
– 3x Flange,
– 18x Screw M8x40 with nut,
– 6x Thimble on the cable ø5mm,
– 3x Steel cable ø5mm, 19m – forged on one side, with a supply,
– 9x Clamp for cable ø5mm ,
– 3x Shackle 0,75T,
– 3x Turnbuckle M10 eye-eye.
Joining procedure:
1. The flange is screwed between 2 sections of the 1.5 mast (between 4-5 truss element for level 1, 7-8 element for level 2 and between 10 and 11 truss element for level 3).
2. Through the mounting hole in the flange we put the shackle with the pin towards the mast.
3. We attach a guy-wire cable to the shackle with a forged end (where the thimble is installed).
4. The free end of the cable (the one without the thimble) is put through the thimble attached to the turnbuckle.
5. The free end of the turnbuckle is anchored through the eye to the foundation (fixing element depends on anchoring – on the customer’s side).
6. We choose slack on the cable, put on 3 cable clamps and tighten. It should be remembered that the first clamp “loosely” pull as close as possible to the thimble – so that the cable clings nicely around the entire circumference and only tighten. Failure to select a slack may result in the cable sliding off the thimble and improper connection operation, or in the long run the cable may rub. The clamps are separated from each other by about 30cm, and the remaining cable supply is cut or scuffed – as it can be useful when changing or moving the mast anchorages.
7. The procedure is completed by selecting the remaining slack with a turnbuckle for light cable tension (approximately 100kg maximum force). Significant excess of cable tension can lead to deformation on the mast hinged foot (steel triangle), or break threads on steel hooks/anchors in the foundation.
The kit has been designed taking into account the correction for long-term corrosion of the cable – the breaking strength for the new kit is 800kg per cable.
WARNING: Setting up antenna tower can be very dangerous and can result in death and property damage, if you are going to use extra segments and heavier antennas definitely use guy wires! Building higher than 6 meters and using heavy antennas can be very dangerous! Be vary of any overhead electrical/telephone wires when raising the tower!
