3  VSAT technology and installation / Dish pointing and alignment / Modifying Prodelin Series 1250 from C to Ku band

>>>Modding an old Prodelin Series 1250 from C to Ku, on a remote island...

Have Ku feed assembly but need to position it on the C "platform"...
Question about the focal length: compared to the position of the
existing C horn mouth, where should the Ku window be located? Same? A
bit closer to reflector? Or someone has the "ABCD" dimensions for Ku?
Any estimate highly appreciated!

Thank you

Cheers

I think this is the key document that you need to download and print:

http://www.gdsatcom.com/vsat/Technical_Docs/feed_location_drawings/TD0641.pdf

It has ALL the ABCD measurements.

The document shows ABCD dimensions for various feed window diameters; so good for C or Ku band.

The phase centre of the feed should match focal point of the dish.

The phase centre of a feed is known only to the manufacturer. For a conical horn the phase centre may be at the aperture or further down inside.

If you examine the ABCD lengths, it is to be observed that as you reduce the feed diameter the distance the feed window needs to be from the dish increases. This indicates that for the Prodelin feeds the phase centre is deep down inside the conical horn.


Best regards, Eric.

Dear Eric,

Xicom 200W C-band ODU BUC

These C-Band BUCs have been in stock for several months, but time pressure prevented us from testing them - we don't sell anything unless it's tested and guaranteed!

Earlier this week our engineer finally pulled them out of storage and began the testing process.

...

The results were worth the wait, out of five used amplifiers, four of them performed flawlessly.

We will sell them as single units, or if you need a fully redundant set, we can configure that for you as well.

More details complete with a test sheet at: Xicom XT200C

Sincerely,
Phil Thomas

Regrettably this forum is to be archived and will be converted to a static html pages.

The content will still be accessible, in read-only form, and the loading of the pages will be faster as there is no processing to do preparing each page as requested.

Till the transition is complete (estimated about 1 month to do 6308 topic pages) the forum should still work in read-only mode.

If you want to put a question or give a reply please email me and I will try to do it manually. If anyone wants old messages or images deleted please email me.

Best regards, Eric.

8  Anything else / General and other topics / VSAT training in Douala, May 22nd to 26th
 on: Apr 19th, 2017 at 1:15pm 
Started by Oasis Networks - Ex Member | Post by Oasis Networks - Ex Member  
Dears,

I am planning to travel to Douala, Cameroon, to provide VSAT training. The dates will be between 22nd to 26th, and is intended for engineers with practical background.
Basically, we are going to cover the following topics:
- Theoretical background about electromagnetic waves, polarity, frequency, the geostationary satellite system, modulation, FEC, some discussions about access methods and different standards and different types of networks and more.
- Practical aspects of the Field Engineering work: Consideration where to locate the dish, cable run work, antenna foundations, work planning and more.
- Work methods, Oasis work procedures, code of conducts, safety and health consideration, working with Oasis portals (training, project and future overall platform).
- Practical part on the field, installation, troubleshooting scenarios and flowcharts.
- Q&A etc.

Cost of the curse is $700 per person, each needs to take care of the logistics though we will probably manage to organize better price at one of the hotels near the training location.

Certificates of Oasis training will be provided as well.

At the moment looks like we have only 5 available seats left. I am planning another training in Uganda toward September, and probably another one in DRC or CAR around December or Jan.

For more details, please contact me by email.

Kind Regards,
Nimrod
