As a general rule for a yagi antenna (assuming a fixed number of elements) the longer the boom length the greater the gain. Forced by economic matters yagis are more often squeezed into a smaller boom size than is optimum for best performance. Hence I don't think it is a any problem for the designers of the Step IR to optimize the performance of a ten meter antenna using the element spacing and boom length of a 20 meter antenna. Any votes SteppIR versus Sommer? |

In my mind it is a no contest situation... The SteppIR is very well
thought of by the owners... Another check point is what the serious contestors are running... I know of no one using Sommer, but I'm starting to see them install the SteppIR... denny |

My next antenna is a 3 element SteppIR with the 6m option and 40/30m dipole
option. I currently have a Hy-Gain Explorer 14 with 40m kit. I vote SteppIR. -- Pete . . ZS5ACT ------ Reply Separator ------ "jawod" wrote in message ...

ZS5ACT I have had a three element SteppIR up for three years now. It replaced a pair of Hy Gain monobanders (4 element 20 and 5 element 15). Biggest difference I noticed was that my mast doesn't bend anymore !! And my rotor has about 1/3 the work to do because the torque is so much less. And I have one feedline and no antenna switches, and only one lightning arrestor. And I now get 10 meters, and 17 meters. Wow what a great band 17 meters is. Yes, I DO notice the pattern is not as sharp as the big monobanders, no question about it. Probably a db or so less gain. On 6 meters (I DO NOT have the extra fixed length element for 6 meters) I also have a 5 element M Squared, mounted about 6 feet above the SteppIR. It absolutely blows away the SteppIR. So if you are serious about 6, and don't want another yagi on the tower, give serious consideration to the advice of Mike at SteppIR and get his 4th element. I guess you said that, you are getting the 6 meter element. But I miss that shiny aluminum up there. Sometimes the early morning sun would reflect off all those Hy Gain elements...... Man, that was a beautiful sight. But 30 and 40 meters with the SteppIR? Seems like the only advantages are the ones I mentioned above about the single feedline and simplicity. I can't really see all that much advantage to being able to rotate those single element radiators on those bands. I experimented with learning EZNEC last week and I didn't see hardly any directivity at all in my 40 meter inverted vee. Rick K2XT |

Rick K2XT You could also get a second mortgage on the house and get the Steppir Monstir and rotate 4 elements on 40M. It might mean a tower and rotor upgrade but one can always dream. Paul -- Paul S.

Rick K2XT Since reading Rick's post I should add that I have the two extra elements for six and have had great success. I cannot compare it to another antenna, but I just got a 6M QSL from New Hampshire and I'm in Texas. 73 H., NQ5H |

My ISP has just re-connected the usenet feed after cutting it on Friday. It
seems it happens each month? Go figure! Anyway: Thanks for the feedback on the 6m elements and the 4 ele SteppIR. I want to go for the 3 ele. with 6m passive ele. because the boom length is the same as my existing beam. I could (just about) fit a MonstIR into the yard, but I don't want to get a beam antenna that big. My neighbours have come to terms with the metal monster, as-is. If it got even bigger, I think I would have a bit of a problem with them. I can always change it to the 4 element and then maybe the MonstIR so they would have the antenna 'grow' on them. My tower is tilt-over and crank-up so antenna work is quite a bit easier than climbing each time. My current beam has a rotatable dipole on 40. For me it is just neater and more convenient than having an inverted-Vee. Another big advantage for me with the SteppIR is that it is mostly fibreglass tubing so corrosion will be less of an issue. 40m through to 6m with one feeder! Luverly! -- Pete . .

The solution to that problem is to get a much taller tower so the antenna is further away and therefore looks smaller. ; ) S.T.W. |
