I agree Bob, you have told us this for a long time.
However, my models do not support that idea if I compare my S4 model to my New Vector 4K model. At best however, the difference was not much, and what this looks like to me using the models as a reference...is the difference was so small I don't think anyone could determine a notable difference just using a radio. I also see video of other's comparing signals an often they are talking needles width differences.
Do you really think, because I see something different here...that I'm calling you a liar?
I know modeling is not perfect, but neither is looking in the air at your antenna work, listening to your radio, and/or recording signals, propagation being what it is.
In all my experience fooling with my real antennas I have seen occasions when one antenna seemed better than another, but when I compared them, signal for signal over some period of time with some of my regular contacts, and then later compiled this data into a recap...I just didn't see anything near an S-unit of difference like many claim. But I don't consider them as liars.
I know there are issues with the testing I have done, but I did what I could and I was surprised to find that all my antenna performed about the same when I tried to get the current maximums at or near the same height. Maybe this lack of difference I see is because most mount their antennas all on the same height mast, regardless of where the current max is.
Regarding my modeling, I think I've added extra length to both S4/NV4K models that you and Donald have reported to have added to your antennas before. I don't remember specifically what effect this had, but maybe I'll check that out and report back.
Bob, this is bull crap. I could complain about your testing too, but I don't. I figure you did what you thought best, and reported what you saw.
Toward the end of my testing days I went to a lot of extra trouble to mount most of my antennas on the same mount with everything in the setup the same. I recorded the same guys signals I always did, sometimes for a day or two and sometimes for a week to a month. I recapped those reports too, and surprisingly these guys signals were very consistent with the testing reports I got earlier...and this was with two antennas mounted 36' feet apart on an antenna switch.
Every where you look in the world of communications antennas you see installations of multiple antennas mount much closer together than mine.
Donald makes similar claims, but on his Website he shows his Dominator mounted with a score of other antennas right there in the same area.
Maybe I'll post on the rest latter, I'll have to restudy the rest.
