Steel Towers
MC-900/MC-1000 Telescopic Mast 3x3 or 3x4m
MC-1000
Hot dip galvanized telescopic masts, consisting of three sections each 3m, 3.5m or 4m length. PLus top unit with 1m length and socket.
The masts are available in different version with a edge size of 30 or 40cm. Extended height is up to 12m, depending on model.
The masts are suitable for a 'standard' HF beam or multiple VHF Yagis. We do not supply a static calculation with these masts. In Germany the regulations usually require a build permit for masts above 10m height. This permit normally requires a static calculation. So the 3x4m masts are not permitted to be extended higher than 10m. By changing the attachment points of the steel cable the max. height can be limited to 10m, resulting in legal operation. With the now longer overlapping segments the bending stiffness is higher.
The 45° cross beams of the masts are made of solid material (not tubes). Additionally one side has horizontal cross beams of the same diameter. With this you can climb up the mast in principle, although we do strongly warn about climbing a telescopic tower.
The masts do have a simple hinge at the bottom for easier installation, see picture. Included in shipment is an ALKO winch with 350Kg traction force, incl. steel rope. Also included is an universal base plate which can be bolted to the ground or used in a concrete basement (see pictures).
The top unit offers enough space for a rotator and contains two friction bearings suitable for 50mm tubes. The MC-1000 comes with a ball bearing at the top position. A short and simple steel tube is included with each mast. But this is a simple tube without any strength specification, suitable only for lighter antennas. In case of dounbt please replace this with a higher specified tube. The achors required for a concrete basement are not included and must be ordered separately (see below).
