What about the LNB arms, are their length not extended accordingly to cater for the new focal point?

Thanks againFocal point remains the same.
A pf dish is basically a section of a sphere and the focal point is it's center.. if you complete the absent parts of the sphere which is essentially what is done when building extensions the centre/ focal point doesn't change and the arms remain.

The quality of work is on point.See also fibreglass petal extension

Ohhh alright, I now get you. If you continue adding the missing parts you will basically get a ball. Thank you.
Not true. For the lnb to fully illuminate /"see" the whole reflector you should adjust the focal distance/length.Focal point remains the same.

An unstable tp can stabilize by extending the plate, if all is perfect you should get/calculate new focal length.
True it has two focuses.Haha... Imagine you get your new focal point and build new arms .
BUT remember radio waves reflected by the original sections of the dish (Which you're extending) will converge at the Original focal point... Where they were meant to converge
AND you build a new focal point for your extended parts..
YOU end up with a dish with TWO focal points.. one below the other the a original Focal point and a new focal point for your extensions.
[emoji2956][emoji3][emoji3] powerful dish.
Ckeck your set up.. 2.4m OKCurrently the BUD is on 68E and 76E, no Disney while 76 is prime.
A little problem you have over there is each and every extension seems to have their own curvature profile and thus collecting reflections at their own little Focal points around the main focal point..This has been my WIP for sometime. I will adjust the focal length if i get time. The dish performs very slightly better than a 6ft.
1. The additional weight alters the shape.
2. The dish is very deep as the initial curvature shapes the curve of new petals.
3. A very deep dish cannot produce a sharp beam wave so it may have a low efficiency.
4. A deep dish is not good for Ku band.View attachment 1173568
Yes a smooth Ball but the centre remains
Starsat 2000 extreme HDWhich receiver are you using
It said that ARQ never went missing... They just reduced the signal strength to a level you'd need a 12ft to receive it..Nikama Jeshi wameenda ki Arq ...... sad.
