Re: [Elecraft] k3 STEPPIR 6Meters
In my design, you can make the changes to a steppir on a tower if you can reach your passive 6M element. You don't have to order any parts to make this work. The GM3SEK modification can also be made "on the tower" as both the new elements are less than 4 feet from the mast. Ian spent considerable time modelling and working on an element mounting system to provide stable operation with changing weather. 73, ...

Re: [Elecraft] k3 STEPPIR 6Meters
There is always an ongoing discussion about this in the SteppIR forum on groups.io. The key to making the SteppIR antennas anything more than pathetic on 6M is adding a fixed reflector. Some in the group have modeled and developed 6M antennas on the same boom that rival commercial monobanders on the same length using only the original driven element as being adjustable.

I think it makes the 3 element antenna a 4 element antenna on 6 meters and greatly improves the F/B ratio and adds a small gain. I have not added thisto my Yagi, since I seldom have operated on 6 meters, but it looks like it may be possible to add it to the boomfrom the top of the tower without much trouble since it is not too far out from the mast. At one time I think the costwas less than $100, but probably you could build your own element if you have aluminum scrap antennas. Just an idea, since every dB helps.

Yes, if you can't afford (or can't rig) a dedicated 6M antenna, the 3-el with the added director is a decent, but not great, antenna. I had a lot fun with it. The 7-el G0KSC LFA I added a year ago is a very nice improvement if you're serious about 6M. :) 73, Jim K9YC __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to arch...@mail-archive.com
