Marconi's Gain Master vs. a correctly installed Starduster

[Marconi]

I've already posted my problem with my Starduster coming-in at the bottom of the group in my last recap of Signal Reports, and what I found when I took it down. Well I fixed it and I've got it back up at 52' feet vs. GM at 59' feet to the tips. I don't have a problem with my VOM check anymore and the bandwidth curve looks pretty typical too. So, I'm in the process of comparing these two side by side again, with the GM out in the back of my yard and the SD'r near my shack.

I still need to get the SD'r up about 2'-3' feet higher for the bottoms of both to be the same and make the test Even-Steven. I'll fix that as soon as the winds go down.

Marconi, if you don't start learning to lie about your signals on the antennas you are not going to be popular with the in crowd. And you know that will mean no date to the prom.

Well Homer, unfortunately life has taught me how to lie, but I tend to believe others when they tell us they see greater differences in their experience, even while I might question the process...which IMO seems fair. In this world of pie-in-the-sky imaginations...the reality of truth won't hurt em'.

He doesnt have to lie the picture tells a 1000 words they are right in the near field of each other No magic numbers just interaction between antennas... :bored:

I like the idea of putting up 2 identical antennas and testing those.

I can't deny they are close together, but nothing I do suggested to me that one affected the other in any way as I can tell. I did do similar testing with most of my antennas standing alone, and I still see little to no difference. I see more difference in the particular contacts that I record than I do with their signals when the DX is not so obviously working.

I can't prove there is no affect with these antenna side-by-side, but I don't think you can prove anything to the contrary either. Mr.S, you make a big talk, but I see very little contributions from someone who claims to have tested thousands of antennas on an Antenna Test Range. I'm from Missouri, why don't you show me?

I even sent you the wires view of several of my latest Eznec 5 models, requesting you and/or Moleculo to correct any problems you find, and nothing so far. IMO, that too speaks loudly like a 1000 pictures.

Mr. S, why don't you put up or shut up, you're not adding anything of value to my thinking and you don't follow up on your promises either.

Kamikaze, if your suggesting someone install and test/compare two fairly identical antennas, I did something similar a while back using the New Top One vs. Old Top One with a full 1/4 wave radiator in the top...instead of the 50% top hat design Avanti did years ago with their AstroPlane.

If this is what you're talking about, then here is a link to the Signal Report results I got and posted to this forum:

[HomerBB]

I read where some think A - B testing is the only reasonable method of comparisons, and where others think A - A method is best.

One day all the antenna experts will get together and arm wrestle, and the winner will be declared right.

What!? arm wrestling has nothing to do with it ? ? ?

I saw that thanks.
I'm proposing 2 completely identical antennas with identical feedline type and length. No room for variables.

Kind of a test the test.

You're a mud duck.

You're calling ME a muddick? I've heard your stuff. You're the duck, duck.

That's a real astute observation MrS, it takes a real pro to see the distinction you bitch about all the time.

After you're considering what I do and finding it totally without merit, what do you have to say regarding W8JI's antenna farm layout and the space between the antennas noted there?

The only thing I'm going to say about that antenna farm is I think I'd be willing to trade mine for that one. I'm guessing it should make a minor improvement in my ability to work DX.

I don't know about that SW, we're told all the time by our critics that if conditions are right that DX is easy, with just about anything that will present a good load for the radio.

I worked Hawaii, Columbia, and Manila, the other day on my GainMaster, Starduster, and my MarconiX noted below with only one 102" radial at a tip height of 29' feet. When I switched from the Gain Master to the MarconiX the signal hardly changed and the contact was just as good into Manila and that is pretty far away. Of course there could be some conditions working at 11 meters that do not prevail at 160 meters, I don't know. My point to MrGubber :bdh:was that it don't matter how close the antennas are...if they work as intended.
