SteppIR 3 Element Yagi, Instruction Manual

Page: 21 / 34

On all elements we now include double wall polyolefin heat shrink, part number #03630. Each tele-
scoping pole uses 3 pieces of the 1.5” x 3” long heat shrink, which forms an adhesive bond that is
heat activated. Once finished, the seal is secure and waterproof. This new process replaces the use
of electrical tape and silicone wrap.
This product requires a heat gun for activation of the adhesive. When positioning the heat shrink,
place it so that the joint of the telescoping pole is centered in the middle of the heat shrink. The
pictures below exhibit how this is done. Apply heat around the entire area of heat shrink.
Note: There are 4 blue colored lines imprinted on the tubing. The joint is considered done being
heated and waterproof when the lines change color to a yellowish green. Each line needs to change
in color to ensure even adhesion temperatures. With this change, there is no longer any need to
tape the joints on the loop elements.
