4 El Steppir Retrofit to a Steppir DB32

October 2012

================================================================

Having discovered that a 2 element 40/30 meter upgrade was now available for my 4 element Steppir, I thought I would order it and retrofit the antenna. Although this upgrade is not mentioned in the Steppir literature, after many requests from 4 element Steppir owners, the folks there have made it available. The following photo show is a short documentation of the upgrade.

Getting Prepared for Retrofit:

Removing 2 existing elements for retrofit replacement

Initial tilting of tower

Continue tilting tower over

 

Tower now in tiltover position. I am working on removing the existing elements and Element Housing Units from a ground level position. As is visible here, the old element to housing boot is in excellent condition as were all the existing elements, housings and boots

 

 

 

Exisitng element vinyl tape wrap - obviously in great condition after 2 years of UV exposure

New Steppir 2 element 40/30 meter retrofit parts

New 40/30 mtr parts displayed. Notice the 8 new fiberglass element tubes which will be built with the composite "sweeps" to form 2 new completed trombone elements. New boots as well as 2 new Steppir housing units and all associated hardware are included.

 

Close-up of new parts. In the center the small box marked "Chip DB32" contains the new eprom for the Steppir controller box. The retrofit requires the removal of the existing 44 pin chip and replacing it with the new one. The retrofit kit also contains a chip removal tool for this process
