43.3 feet Heavy Duty Extended Fiberglass Push-up Mast MK-6-EXT
The MK-6 Series of masts (including the MK-6-EXT masts) are, by far, our most popular masts for many reasons. The masts are light weight and short enough, when fully collapsed, to manipulate the quik-clamps from the ground or a short step ladder. This mast will get you above most obstacles to achieve maximum height, line-of-sight, maximum gain, and the best reception. Our masts are completely adjustable along the entire length of each tube.
See the photo gallery to see dozens of pictures, all taken by customers, of our mast systems being used for a number of different applications.

GUY YOUR MAST
A tall structure such as our full-length model MK-8 or MK-6 series masts (including the HD versions) MUST be guyed and kept under control with guys even while being erected. NOTE: Do NOT use metal guy cables with this mast system! Metal cables are conductive and HEAVY and add significantly to the vertical loading of the mast. Enlist three friends, family, or neighbors (or 4, if you choose 4 point guying) to stand in the approximate locations of the guy anchor points, and to hold the guy ropes and “feed them out” as you extend the mast, all the while being certain that the mast stays vertical. We recommend guying at least two levels with three direction guys. The kit below comes with everything we offer to guy your mast effectively.
