re:centerfeed dish

[mrfredted]

Hey All...I seem to be having trouble getting this to you guys. I have acustomer who has an older 14', four section, fiberglass centerfeed dish. He has asked us to try y convert it to satellite 119 for DNW. We spent about five hours on it y can't seem to find the signal.Would the coordinates be different for that size than they would be for a 2.4m dish? Any help is really appreciated. We are based in Costa Rica.
Thanks in advance.

What are specifics of the LNB that he is using. If its an old c-band LNA, it's not gonna work.

re:centerfeed

Was using the regular dual LNB

don't know too much about center feed dishes but does the dish allow for the LNB to be set at various focal depths.

offset or center feed

Is the 2.4 m dish an offset or prime focus? If the 2.4 is offset the yes the angles will be different. If not there is the possiblity that the 14' is not KU compatible and the mesh inside of it is not reflecting enuough signal back to the feedhorn. Also it has to have a DBS KU LNBF.

I'll soon be embarking on a similar project and will let you know how I make out.

2 STRIKES against the dish working you are way out of the signal area for US reception. A fiberglass dish by it self can't reflect microwave signals they pass through the fiberglass. Inside the dish is a layer of metal to reflect the signal for "C" band hole size didn't have to be as small or as perfectly shaped so most Fiberglass dishes did not perform well at Ku band frequencies. There are exceptions like "Prodelins" but most fiberglass dishes were "cheap" and worked for "C" band but little else.
