Andrew, Patriot, Prodelin, Paraclipse...etc
i'm planing to manufacture one piece satellite dish prime focus ku-band size 2m and 2.4m made from aluminium.
to start with this plan i need some info on good reception satellite dish on the market. please any advice which model or brand i can follow. and also will make the brand after Austech members suggestions...peace!

Why reinvent the wheel? I'm sure it would be more cost effective to buy one already on the market.

ask leahjet, remember he made some a couple of years ago when he had nothing better to do out of wood and some refective sheet material but I cant remeber what.
I have a 1.8 metre Off Set Prodeline Fibreglass dish Ku/C band capable sans lnb supports and mounting and if I had 'My Druthers'. no way would I use aluminum in a dish that size due to the weight difference and I feel that the fibre glass would be less affected by temperatures causing distortion to the dish surface.
I also have a redundant ex Ipstar 90/1 metre dish, again firbeglass so ask your self why well know companies are using Firbeglass as compared to aluminium for any size dish.
I also have a centre feed dish under a metre diameter with seperate petals but its made of pressed metal which is now rusting away.
The difference to 'moulding' and 'casting' needs to be seriously considered as one is basicaly mix and pour 'cold' into a suitable mould where the other is a full blown foundry with a furnace and casting moulds that needs properly controlled cooling down after casting to prevent distortion or cracking.
I am not suggesting that neither requires expert engineering for a proper construction but after a dozen stuffups I reckon even I could get it right using Fibreglass but aluminium??
I stand unequivicably behind everything I say , I just dont ever remember saying it !!

Fibreglass dishes must have a metalic surface embedding in them, otherwise the signals pass straight through.
Fibreglass dishes often have steel or aluminium sheet embedded, but most use a steel/aluminium mesh.
You may be surprised to learn aluminium dishes often weigh less than fibreglass dishes of the same size/density.
The majority of large commercial dishes are aluminium (some with fibreglass covers to protect LNB/feedhorns, etc).
me thinks hes in indonesia and wants to make them dishes (expensive in indo) for aurora hence the other post wanting pic cards....
I found the one piece satellite dish have much better receptions.
The satellite dish are to received Australian TV Channels, they are really good to watch. Aurora Vast Austar FOXTEL they are all good signal here in Bali, and of course watching with them original TV Decoders card.
I may also to market the satellite dish into Australia.
A good reliable satellite dish made from Austech members ideas and contributions.

But we only need a 65cm dish for foxtel/austar and aurora.

dongwei, would your aluminium dishes be pressed, or drawn (spun). A drawn parabola is more accurate, but if you are going to press them, you might want to think about manufacturing an 'offset' style dish. I know they aren't as popular in Indonesia, but they are more efficient, and a smaller dish can do the same job as a larger prime-focus dish.
