found your problem! you put the radar too high! it is on top of the railing on the platform instead of partially behind it.
also, there seems to be an different stabilisation foot.
antenna size is taken as everything above the stabilisation foot, as that part, as shown here, can vary between different ships, even within the same navy (the dutch ship rotterdam carries an DA-08 with an different stabilisation foot then the one carried by the heemskerck class, which is shown in my drawing)
then, looking at the measurement you gave, my version is actually correct.
for the IFF bar. I think you are right that the IFF bar could be one pixel lower. BUT not 2 pixels, as you have done. placing it one pixel lower though, creates an double black pixel line, which is frowned on in shipbucket. it is allowed in cases like that to overstate parts sizes, and that is exactly what I have done here.
the bar should be a bit lengthened for the vasco da gama drawing though, as you have done.
also,
http://www.areamilitar.net/directorio/IM_sys/da08_1.jpg this picture shows an different version of the radar then what is depicted here. that version can be found on the dutch parts sheet as well, and as you can see I have there shown the IFF bar as you have shown (although that bar is an smaller type, as again these can vary between ships
)
EDIT: also, an measurement based on the official plans of the dutch L-frigates, which used the same radar, gave me 33 pixels, effectively making my drawing 2 pixels too small!
so, case closed, the main radar, apart from the IFF, stays as it is.
EDIT 2:
here, doesn't this look better?
also, please lower the STIR's one pixel, as right now they form black blobs, which, as told above, are considered ugly in here. same for the phalanx.
Great acelanceloet..
Thanks for the patience solve this case, and sorry on the time lost..With a such newbie error..
so i was right, the antena has the dimensions wrong..
Yes it fits well now.. hehehe..
