41ft / 12.5m telescopic aluminum mast

  • Description


41ft aluminum mast.  This mast is a trade-off between collapsed length and overall weight versus portability.  Can be used easily for Field Day or similar portable operations but also suitable for permanent installations.  For a more heavy-duty mast at a similar height see the information on our 47ft / 14.5m HD aluminum mast.  The 41ft mast is approximately 1/3rd lighter than the 47ft HD (26 lb vs. 39 lb) and the collapsed transport length is 14 inches shorter (5 ft 5" vs. 6 ft 7").

The individual sections are interlocked with strong high quality stainless steel clamps with 8mm allen screws.  An 8mm allen wrench is supplied with the mast and no further tools are necessary.  The mast should be guyed at one or two levels.  For quick portable use, we also sell a knob screw kit.  The knobs install in place of the 8mm allen bolts on the clamps and allow the mast to be quickly taken up or down.  Knobs are not suitable for permanent installations.

The mast can be rotated by hand or a light duty rotator like Yaesu G-450 can be placed at the bottom to turn the whole mast. 

Guy hardware allows the mast to be guyed in 3 or 4 directions.  Slip-ring guy hardware allows the mast to rotate inside the guy hardware.  Rotor adapters (70/50mm) are available as the base of the mast is too large to fit any commercial Amateur Radio rotator clamp opening directly.  Turn the entire mast and antenna from a base mounted rotor.

Antenna can be mounted directly to the mast or with optional 35mm standpipe that fits onto the top of the top section of the mast.
