MAST KITS AVAILABLE
We have seven mast kits available that will work with our Tripod Mast Mount. Ranging from as short as 12.1
feet when fully extended, that could fit in a luggage bag, up through the 50 foot tall MK-8-HD mast. These
Tripods will accept any mast with a 2.5 inch OD Round base tube.

When selecting a mast, do not just look at the maximum usable height. Be sure to take note of the differences
in the different models. The HD and EXT have a bottom tube section starting at 2.5 inches where the STD
starts at only 2 inches. These diameter differences are very pronounced when trying to figure out what you
want to support by the mast. The STD models have a piece of 3/4 inch tube at the top making it ideal for
supporting things like a vertical wire antenna whereas the HD models have a 1 inch top section which is much
more stiff than the 3/4 inch tube. This allows for greater rigidity and allows for support of more robust
equipment. Tube length also makes a difference when deciding as a shorter piece of 3/4 inch tube is far more
stiff than a longer one (a 46.5 inch piece in the MK-4-EXT would be less flexible than the 72 inch piece in the
MK-6-EXT). All of these factors need to be considered when selecting a mast for your application.
GUYING INSTRUCTIONS
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.
Non-
stretch, UV resistant, light, low visibility ropes such as the 1/8”
OD black
double-weave Dacron rope such as the
or “Hexrope
3” (200 foot rolls) that we sell are ideal. If you are not profic
ient in knot tying, we
recommend that you seek tutoring from someone who is OR use a tension device
known as a guy rope tensioner.
