Phased arrays use multiple mini satellite dishes in which the combination of all those dishes go into the lnb if I am not mistaken. I would have thought that those would have been standard on all satellite systems by now when I first found out about it but at the time I didn't take into account the multiple orbital satellite locations and the phased arrays could only pickup one orbital locatio nat a time.
It's perfectly working for multiple points 
( believe me, as I did work for military radar facility ) with very high speed of switching.
In case of sat signal reception, there is no problem to point to diff sat in fraction of second, after that it's up to receiver how fast you'll get a picture of selected channel.

Just for the record, I don’t know if it means much but the CDR used was a blank one.
Don’t think it matters much on “What Artist” you use for the CD, if that was a factor use any CD that you can’t stand much! I will try other types of CD’s later on with a revised portion of this thread!
CD STYLES TO TRY:
CD Standard Music Store Bought Style
CDRW - Blank Then Recorded
DVD - Standard Bought Movie Style
DVDR - One Time Record Blank Then Recorded
DVDRW - Blank Then Recorded
DVD DL - Blank Then Recorded
Blu-ray RE - Blank Then Recorded
Just for fun: Laserdisc!
Laserdisc is really not CD size. The standard home video laserdisc is 30 cm (11.81 inches) in diameter and should be easy to try but it is a flat surface so should be interesting!
FYI:
Yes I do still have a Pioneer LD-700 that my father bought in 1984!
The snuff can lid was a task and will give any smaller reflectors a try for you guys! That was a hair puller and a half!
I had a blast doing this project and enjoyed reading all the commits posted.
Now that we can move on with the thread, it will be interesting to see your projects implementing C-Band, and KU!
This thread is not necessarily just about dish size smaller or bigger, anything goes here! Read the title of this thread, it says it all!
Anything that sounds impossible or we think can’t work in theory, by all means you are welcome to prove otherwise in this thread!
Now go try something off the wall and post it!

Wow laserdics, I haven't seen any of those since about '86 or '87! I think you could get a 2 hour movie one them, but they would stop after about an hour and you had to flip them over like a LP to get the second side to play. In highschool a girl I dated for a short while had a father that had a collection of about 1000- 1500 of them. Her father was a real movie buff and only bought them, never rented movies.
They did have a lot better picure quality than a VHS tape did, but I guess the reason they failed was people wanted to watch an entire movie with out geting out of there chair to flip them over. At the time they had about or slightly better quality than a BETA tape, but the inconvenience killed them, the same as the BETA's sligthty less play time than a VHS killed the BETA. Add in that they were play only, while both VHS and BETA could record, well you know the rest of the story.
Mayby you could cut one up and try to make a fresnel lens dish out of one! That should work better than a flat platter would. Or you could just save the disc to wacth it again in glorious SDTV, without the low res digital SD crap we can now only get on digital!

I have about 40 laserdiscs. I think they died because you could not record to them and tape had the rental market. They were much more convienient than tape. With tape you had to rewind. The price of the movies kept the laserdisc to only those who wanted the better picture and sound. I remember buying the StarWars triliogy for $399.00, and most others for $50.00-$100.00ea. The RCA cartridge disc system dominated the rental market at about the same time, so laserdisc was left for only those who wanted better. Then the small size of DVD and a digital picture and sound. I remember taking one of my bond movies to the local TV store and playing it side by side with the DVD version. Just hearing "For Your Eyes Only" in Dolby surround was remarkable. I ended up buying the little Amgstrum speakers (4 of them) due to that movie. Still use them today.

Very nice looking cherry wood cabinet, and excellent performance.
I guess we are old timers here Larry1! I get that all the time with my old vintage equipment! I have a pair of mid 70's Bose 901’s here the first models that came out in the 901 series that are rated “Unlimited P-R!” I would not try to run 500 watts through them though but they have been very dependable and everyone that sees them tries to wiggle them off me!
Being in Broadcast radio all the years I have accumulated a lot of audio and video things mostly audio though! I have enough equipment here to start an AM & FM broadcast museum! Old Cart decks to vintage half track machines that used to do automation! I also have an old Go Cart automation head end for you fellow broadcasters that seen or used them back in the day! It is still remarkable to see it work!
I have old Marti’s to one vintage Harris 5K tube type FM transmitter! Still works if I had some Heliax cable an antenna I would do a LPFM station! My wife thinks I am nuts keeping all that old equipment!
I have donated some to COSI Science Center of Columbus OH for their old Broadcast exhibits awhile back but still have tons of stuff literally!
Right Back On Thread Track,
The Laserdiscs were ahead of their time back then when they first came out! I have about 50 discs to play on my player; they were about $50 -$100 or so dollars then per movie, more so for sets! Not cheap but the picture surpassed the old VHS & [ame="http://en.wikipedia.org/wiki/Betamax"]Betamax - Wikipedia, the free encyclopedia@@AMEPARAM@@/wiki/File:Question_book-new.svg" class="image"><img alt="Question book-new.svg" src="http://upload.wikimedia.org/wikipedia/en/thumb/9/99/Question_book-new.svg/50px-Question_book-new.svg.png"@@AMEPARAM@@en/thumb/9/99/Question_book-new.svg/50px-Question_book-new.svg.png[/ame] by far! Dolby surround was remarkable on them!
Yes I Do have a [ame="http://en.wikipedia.org/wiki/Betamax"]Betamax - Wikipedia, the free encyclopedia@@AMEPARAM@@/wiki/File:Question_book-new.svg" class="image"><img alt="Question book-new.svg" src="http://upload.wikimedia.org/wikipedia/en/thumb/9/99/Question_book-new.svg/50px-Question_book-new.svg.png"@@AMEPARAM@@en/thumb/9/99/Question_book-new.svg/50px-Question_book-new.svg.png[/ame] also with tons of tapes!
Sorry for the little side track on the thread but I started it! LOL!
You brought back some memories with the Laserdiscs Larry1 that I still relive!

Neat stuff.
When I was younger I was able to catch C Band signals bounching off a chicken wire fence.
I saw this in a Popular Science or Popular Mechanics magazine in the early 80's. You could build a wooden frame (about 12' square) and then cover with chicken wire to receive C band signals. I was going to build one myself, but later purchased a 10.5' Luxor satellite dish instead once prices began to drop.
That is neat Popcorn!
Wonder if that issue (whatever one it was in) could be found? Be nice to see the plans and build one today! With the equipment today and newer satellites up there but it would yield better results!
Would be really interesting to see the plans and one of us Members build such Chicken Dish!
Bet you could use the measurements of any c-band dish and make replica or something close!
I can see the Chicken Wire Dish will be the next project brewing here on this thread!
I can see it in Members Signatures now, "Proud Member of the C-Band CWD Club"! :haha

Probably something similar to the pic in post 148 in this thread - http://www.satelliteguys.us/fta-shack/131140-pics-dish-farm-post-yours-too-8.html
This summer am going to try to get c-band off a 6ft beach ball by securing an lnb at one end and wrapping the bottom third with aluminum tape used on Boeing engines.
I got the idea while googling portable c-band. The result looked like the Ion cannon from Hoth in The Empire Strikes Back.
Cheers, K

Wow that is cool. I wonder if they would send one of our fta staff one to review.
