SteppIR - Why Compromise?
The SteppIR antenna was originally conceived to solve the problem of covering the six ham
bands (20m, 17m, 15m, 12m, 10m and 6m) on one tower without the performance sacrifices
caused by interaction between all of the required antennas.
Yagis are available that cover 20 meters through 10 meters by using interlaced elements or
traps or log periodic techniques, but do so at the expense of significant performance reduction
in gain and front to back ratios.With the addition of the WARC bands on 17m and 12m, the
use
of interlaced elements and traps has clearly been an exercise in diminishing returns.
Obviously, an antenna that is precisely adjustable in length while in the air would solve the fre-
quency problem, and in addition would have vastly improved performance over existing fixed
length yagis. The ability to tune the antenna to a specific frequency, without regard for band-
width, results in excellent gain and front to back at every frequency.
The SteppIR design was made possible by the convergence of determination and high tech
materials. The availability of new lightweight glass fiber composites, Teflon blended thermo-
plastics, high conductivity copper-beryllium and extremely reliable stepper motors has allowed
the SteppIR to be a commercially feasible product.
The current and future SteppIR products should produce the most potent single tower antenna
systems ever seen in Amateur Radio! We thank you for using our SteppIR antenna for your

SteppIR Antennas — 2E - 3E High Wind Kit i
The high wind kit for the 2 and 3 element Yagis will consist of additional hardware to provide a stronger and
more secure mounting in environments where severe winds may be a problem.
This will be a pictorial description of the assembly of this kit:
Put the two mast plates together making sure all the holes line up
Put a split washer on the 3/8-16 x 4” SS Full-Thread Bolt
Insert the 3/8-16 x 4” SS Full-Thread Bolt through the two plates as seen in Picture 1 &
Picture 5
Install a standard 3/8-16 nut and tighten (make sure all holes align)
Install a standard 3/8-16 Nylok nut as seen in (Picture 7)

If you are going to mount the mast plate to a temporary mast then continue your antenna assembly:
Put the mast plate assembly against the mast
Assemble a reinforcing strap with two 5/16-18 x 4” SS bolts into a 2” short saddle (with center
hole) and install as seen in (Picture 13).
Install the 5/16-18 SS Nylok nuts and tighten
Repeat for second mast clamp

Boom Installation for 2 Element (20m - 6m):
Measure the overall length of the boom and mark the midpoint
Boom Installation for 2 Element (W/40m-30m Dipole):
Temporarily mount the boom as shown in the 40m-30m Dipole manual choosing your
location
Mark the boom directly under the EZ-Eye stud
Remove the boom.
Continue:
Place the boom on a flat level surface with the element mounting surfaces up
Check to make sure the element mounting surfaces are level
Mark the top center of the boom 2” from your center
DO make sure the mark is on the top center of the boom
Center punch the mark
Drill straight down through both sides of the boom with the “N” (.320”) drill bit (that is
provided)
Install the 5/16-18 eye bolt with the eye parallel to the boom (Picture 15)
Install a 5/16-18 SS Nylok nut and tighten
Put two 3/8” flat washers on the EZ-Eye stud (Picture 16)
Hang the boom, using the EZ-Eye, on the EZ-Eye stud
Put two more 3/8” flat washers on the EZ-Eye stud (Picture 16 )
Install 3/8-16 SS Nylok nut (do not tighten now) (Picture 16)
Install two 1-3/4” saddles on the first side
Insert two 5/16-18 x 4-3/8” SS bolts
Install two 5/16-18 SS Nylok nuts (do not tighten now)
Do the other side the same way
Adjust the two Nylok nuts on the EZ-Eye stud to make sure the boom is level
Tighten the Nylok nuts on the boom saddle clamps and EZ-Eye
NOTE: The EZ-Eye can be adjusted later to relevel the antenna by loosening the bolts on
the boom saddle clamps and then adjusting the two Nylok nuts that position the EZ-
Eye. Be sure to tighten all nuts when finished.
