From what I've read in your posts, I really don't care.

Aside from any severely diminishing returns, that would be a fairly effective way to create a mostly solid cone which I would imagine could increase the efficiency of the design.

Sorry Eddie, I'm not tracking with your "Aperture" idea. To me an aperture is a slit, hole or opening where light or sound, (in this case RF) would be able to get through in a limited way. I don't relate to transducers in terms of apertures, that to me would be more like an area between two...

Oh, I'm sure that must be it, oh yeah, 'Meter calibration' - Yep, both his dissimilar radios (including a nice newer Kenwood 570) just happened to be out of calibration the same basic amount in the same way and for some reason that makes different antennas look similar in performance... - Talk...

Something I've been wondering about is feed line phase. We all know about velocity factor in coax, and how a ¼λ of, say, 75Ω coax can be used as a matching transformer to match from a 100Ω impedance feed point, (like what's seen when directly feeding a full-wave loop) down to a desired 50Ω...

No, I doubt they went to showing far field when the CST image is evidently intended to show what is as near field as possible, the RF radiation which is coming directly off the antenna skin. I really don't know how I could be more clear about the issues presented in my previous post...?

Do you guys also have to re-sign in after only about 10-15 minutes? I have to continually sign-in, sign-in, sign-in all day long, every 10-15 minutes in order for it to know it's me and offer the long page type I have selected, even though I'm not closing the window nor deleting my cookies...

I'm only disheartened by the reports that the SGM is dieing from power levels well below it's advertised power handling capability. I plan to put 500w continuous and up to 1Kw pep into mine. If it dies I'll be asking for a full refund, but if it continues to perform as well as it has since I...

No, I believe you misunderstood. Shockwave, I agree with you that 4 cone radials is better than 3, and I'd expect that adding 20 more cone radials would certainly benefit the cone action (which you have described is performing as both a shield and a radiator) to an even higher degree than...

Note the term used here: Average He is averaging all the signal strengths together. That is done by adding all the signal strengths together for each antenna, then dividing by the number of reports. That provides an average. But I have owned several rigs with meters which easily show a .2...

To re-ressurect this ancient morsel... Well that was an interesting and fun hour of reading. What it left me wondering is why Sirio, with their chamber and all their testing equipment, are not marketing the .82λ or 7/8λ but are now marketing exactly what I tried decades ago, the simple 3/4λ...

OK, so the SGM is due south of the other mast/ antenna (Neo Top One, Imax, etc..)?

Nice to have the forum back! Why shift the attention to me? He asked YOU MrSuburban, and you gave him a load of dirty baby diapers instead of some of that invaluable "by-the-hour" wisdom & genius you're so eager to blather on about. Well, at least you did the easy part, you talked about it...

Nice to have the forum back! Eddie, which direction is the Imax from the SGM mast? And about how far, ~35'?

The +3B was brought out with another wire added for the radios which required a non-grounded common switching wire (blue) for TX/RX switching. Other than that I don't believe there's an iota of difference. When I opened my +3B I saw the same solder pattern on the bottom side of the preamp...

Shame on you Booty, you "Sponge"!! WTF are you doing out here anyway, trying to learn?!?!? Actually, you asked about modding the Vector for a non-gamma type of match and your reply was all about matching systems, ignoring the point of your question which was obviously about the length or...

Time to start a new thread for dredging up some of those humorous old 'Let's-take-a-Stroll-down-Amnesia-Lane' memories. I'll start: The year was 1978 and there was I, a carefree (and 'full-of-himself') 18yr old, a waiter at Dan McGrew's restaurant, and living in Danville California, a nice...

This is disheartening considering the advertised power is: "Max Power 500 Watts (CW) continuous, 1000 Watts (CW) short time" - So that should allow at least 500w pep, if not a full Kw @ typical 30% SSB duty cycle. - Now I can't use my SB-200 on 10m without turning it down to...

Hey there Okiebob, If you plan to run big power or mount it up through the middle of an horizontal beam then you're probably better off with the Imax, however, if it's just going up in the air by itself well above other metal objects and won't be seeing more than about 500w-600w pep you'll be...

I like that last statement, it's so good it's quotable. :thumbup1:
