DVB-S2/8PSK on a "badly" damaged Paraclipse 12 footer

[LocutusOfBorg]

Today, I installed a Titanium C1W PLL LNBF on this antenna just to see what happens. Despite the very bad damage to my Paraclipse (see photos) I'm still able to pull in DVB-S2/8PSK signals (58% SQ). I haven't checked other satellites but I found this very interesting and continue to wonder just how big of a dish I really need. The video quality is very good - no pixelation.

just how big of a dish I really need

A 10 footer, in good condition, suffices here. Q typically from high 60's to some 80's.
In the condition of yours, I don't think size matters that much.
(Q values are subjective - it all depends on the manufacturers programmers as to what it's going to say for ?? BER)

There are others on the board who are far more qualified than I to answer your question. BUT IMHO ... I think it just boils down to which channels you want to watch. As you know ... all TP's aren't created equal. On my 10' most of the channels that I watch, the TP's are good and strong. However, with that being said, there are some that are weak, especially on SES 2 C 87W. My Winegard Pinnicle is my first BUD. I've never tried to re-mesh a BUD. I'm sure others will chime in that can give you better advice on what to do.

I would like to install new mesh but it's just too expensive. I was thinking of using less costly 1/4" chicken wire so that I could have at least a C-band dish. It's labor intensive though. Not to mention how difficult it is to round up some friends to replace the dish. But, I might just go get another dish, new or used - just got to find one that fits a 3.5 " pole.

Other than the PITA of the para clips,remove the mesh,find a flat surface and use a rubber mallet/rolling pin/2x4 and straighten the panels out.Just need something for the missing piece.Won't be perfect,but a whole lot better than it is now and free other than some time.

You were wondering about the dish requirements for receiving other DVBS2 channels. Notice the FEC value on the 8psk transponder that you documented. 1/2 FEC is very forgiving and not too many transponders use this low of an FEC ratio. 1/2 FEC means that only 50% of the data needs to be received error-free to decode the channel. The other 50% of the signal is retransmitting data for correcting errors.

Most DVBS2 services use a much higher FEC and are typically 3/4 or higher. For example, the ABC feeds on 99w are 9/10 FEC. This means that 90% of the signal data stream must be received without error. Much less forgiving and requires a good reflector, feed and distribution.

I have been able to get FEC signals up to 5/6 on the damaged Paraclipse dish - but not always. Looks like 9/10 is impossible unless I fix/replace the dish. The newer 12 foot KTI has some hail damage but it does pull in 9/10 FEC.
