You folks that have stepIR 3 el yagis..... I believe you can reverse the pattern 180 degs.... by turning the DIR into a REF...and vice-versa. Question is, can you make BOTH parasitic elements into Di
Most of their Yagis, including the original 3-el that I have, have front panel button on the controller for Normal, Reverse, and Bi-Directional. I haven't looked at how the elements are programmed fo
If you want to make a 3 or 2 element array be bidirectional, tune the parasitic elements to the driven frequency. Don't make it shorter or longer. You can run that through EZNEC if you don't believ
Dave, Is there an optimal element spacing for this design? I'd run it through the computer except that computer's at home and I'm not. 73 - Mark N5OT If you want to make a 3 or 2 element array be bi
I'd have to run it through EZNEC to see what the best spacing is, but the "best" spacing may vary depending upon things like bandwidth versus gain. I'll assume that you want maximum gain, but I won'
A couple years ago when I was into 6m MS I was using an old CC 5-elem yagi at 75'. It worked very well and I was able to make hundreds of QSO's out past 1000 miles pretty much at will. Along came som
Hi Gedas, The only important reason for "fixing" it would be reducing RX noise. 73, Jim K9YC _______________________________________________ _______________________________________________ TowerTalk
Hi there Jim. Hope you are doing well and staying safe. Fortunately for me I live out in the country and while there is a farm house etc that can sometimes generate some noise for the most part (knoc
I just got the chance to play with this in EZNEC+. A 2-element version for 40m at 90 feet up in the air seemed to optimize at 67.6 foot element lengths spaced 20 feet apart. The main lobe was 10.65
That 3 element gets quite large for the a couple of DB. Interesting the magic 20 ft number for 2 elements on 40. That has been the standard for a while. W0MU I just got the chance to play with this
