Personally I think the Vector makes more sense described as a 5/8 wave over a 1/4 wave that happens to be a 3/4 that measures 7/8 wave. That said however, you may be referring to the top of the stock Sigma4 antenna being 1/2 wave and the modified Vector type being the 5/8 wave radiator.
eddie,
im saying that in the stock sigma you have about 1/2wave above the
radial sleeve and on the old style vector you have aboout 5/8wave above the sleeve,
"Isn't this what the open sleeve antenna in the ARRL you refer to does so well?"
yes it is, which proves to me YOU bothered to read what i asked people to look at,
go to the top of the class
"I think you are right on the money here, no matter what tall-tale says about the I-10K. Did you notice that he didn't respond to my request to share his Eznec model of the Sigma4? I think he's scared."
i have no idea why toll-free did not share his model info with you, im not sure he used eznec, you know my feelings on eznec and the sigma style antennas, i will stick with ezbob
"Yep, and any CB Goober should be able to sense that about what he sees in that image if he ain't color blind."
that depends on how much 5/8wave snakeoil they ingested,
desert snakeoil is powerfull stuff my friend, at first i thought it was just a case of lack of understanding, people looking at antennas through the eyes of an electrician where ohms laws rule resistive losses, kirchoff's laws are a puzzle to ohmies,
the longer its gone on i realise it can only be scullduggery, nobody can be that dumb as to keep arguing without looking at the evidense or posting anything at all to backup their claims in over 6 years,
it does not surprise me that j-pole jay thinks a hairpin match gives 3db gain over a gamma or that he don't know where the other half of a gamma fed element gets its energy and never shortened an element when converting from gamma to hairpin feed,
i mean its common sense aint it, if a gamma only feeds one half of an element and a hairpin feeds both halfs it MUST have 3db more gain eh lolol,
if people took the time to look at whats been said they will realise that its not restricted to the sigma4, almost everything he posts is cb hogwash,
my signature explains my feelings,
"I don't know about DX yet, but I see a little less signal with my I-10k vs. GM, albeit the GM is maybe 2'-3' feet higher at the mount. I just ran out of energy yesterday trying to push that big old GP all the way up. Yesterday, while I still had my A99 up I was able to talk to an old buddy in Limestone county Texas which is a little over 130 miles NW of me with a 2+ signal on the GM and 2 on the A99. Both antennas made it TX'ing too. We haven't had much if any DX for a day or two, but the A99, TO, and the GM have been making it to Australia and Hawaii, just fine. I can't be sure, but my experience seems to suggest that the TO is a bit more reliable with DX at about all ranges."
i can't comment on the i10k vs gm yet
