It'll be connected to 400 ohm twin lead to a 4:1 Balun (DX Engineering again) and then RG8/U into the shack. Is it better to place it 90 degrees from the center or from one of the ends? The ARRL Antenna Book shows both methods. Hi John, Why all the care for technical description, and then form a question appealing to aesthetics? Better? "Better" is the parent to all answers both planned and ill-conceived. I am forced to fill in the rhetorical blank left there as to you meaning "would there be any impact that exceeds 1dB on way or the other if the antenna were placed, say, diagonally to the G5RV." Probably not. However, this direct answer returns us to the semantic word-chase of just what is meant by "better" and to what degree it is measured. Another fill in the rhetorical blank: "would it affect the tune of both/either to more than 10KHz? if the antenna were placed, say, diagonally to the G5RV." Probably, but "better" is relative to the distance in terms of wavelength, and as the G5RV is a multiband antenna, and the new one comes without pedigree, then that relativity is strained. However, you do not express any inclination for the diagonal, but it comes by association with center placement vs. end placement. The crossed antennas of dipoles find each in the other's null; however, what of dipoles crossed not like an X but rather like a T, or an L? Interesting question that could be easily examined in 10 minutes by the free version of EZNEC. My aesthetics demand a 1db variation or a 10Khz shift. They are met on the one, but not the other - this says nothing of your sense of "better." The T and the X lead, whereas the L and especially the diagonal push the envelope. 73's Richard Clark, KB7QHC Richard "You shore do talk pretty" ![]() I meant "better" as in which arrangement looks best strung with Christmas lights, of course. Based upon your microscopic linguistic analysis, I imagine you use a Microsoft product (at least conversing with you is similar to using one). I use an iMac. It won't do EZNEC (unfortunately). BTW (seriously), will the new Mac products work with EZNEC? and by "work" I mean ... John AB8O |

BTW (seriously), will the new Mac products work with EZNEC? This is something YOU should investigate. Mac now uses that one-and-the-same Intel engine. It is suggested in the press that it runs both operating systems. It costs more to do the same thing, but you get that cool logo. I prefer OpenSource servers, applications, and Linux. I haven't bought a M$ product in this millennium having experienced the Windows Me platform (Chairman Bill's fin du cercle joke on us all). As I pointed out earlier, your question is answered in 10 minutes to all variations that I offered. That analysis even gives degrees of "better" as expressed in KHz and dB (quantifiable engineering terms commonly used in serious antenna discussion). As a spoiler, I will offer that the diagonal placement seriously disrupts both resonance AND gain to the tune of 100s of KHz and 3-4 dB. Of course, the qualifier "seriously" was meaningful only to me; that is, until I quantified it. You still haven't offered us what the qualified term "better" means to YOU. 73's Richard Clark, KB7QHC |

I work both Microsoft, OSX, and am learning Linux. Not that it was asked for, but my experience has been that MS OS is great if you have paid support staff to make it run, Linux is nice, but every once in a while, it kicks us back to 1985, (sorry - unforgivable in 2006) and when I absolutely have to get it done with a minimum of.. what is the technical term?

That analysis even gives degrees of "better" as expressed in KHz and dB (quantifiable engineering terms commonly used in serious antenna discussion). Of course one can get the answer from a modeling program. Of course, the modeling program won't tell *why*.

Mike:
You may be quite right, Richard may not be all bad (I imagine a cadence to his words--much like a drill instructors voice too!) But anyone which likes Shakespeare? Ewwwwwww!
