The KIO hex beam has worked well here at the K2ADA Radio Ranch. Now that we are here most days, I began thinking about an upgrade. Since my primary rig here is a Flex 6300, a multi band yagi or log periodic interested me. Both would “listen” to all bands with a single coax run and I could open multiple slices on the Flex. However, both also have compromises. A mono band antenna for every band would of course be the ultimate, but I didn’t want the multiple towers and switching that would be required.

A dynamic antenna. The Steppir has been around for awhile now. The 3 element (w/ 40m option) will not pose a problem for my Universal 50ft tower and Hygain rotor, and after several months of thinking and rethinking, I pulled the trigger.

Assembly is really straight forward but the instructions could use some attention. Steppir has updated the documentation of each option and sends each as an addendum to the basic build. This is a little confusing and requires a lot of extra work to assemble the antenna correctly.  A phone call to one of the Steppir techs cleared everything up and the build took me about 3 days.  Working several hours a day.

Here are some photos (thanks Annie) of the assembly, and the removal of the hex and raising of the Steppir:

a 60ft lift was used to retrieve the Hex antenna and replace it with the 3 ele Steppir

Thanks to help from a neighbor, we raised the Steppir, and attached it to the existing mast

I’m getting use to the time it takes the Steppir to “remodel” itself for each frequency change.  Signals have been strong and reports have also been good.
