feedhorn.

Chaparral Communications........Corotor II Plus: 11-5000-62 (I would say the non plus version would be fine but I dont see it on there site)....

C-Band LNB.. the ones Im looking at right now..

Norsat International Incorperated......Norsat 8000 series.. link to there LNB page http://www.norsat.com/n22100.asp

for 4dtv stability is important but how much so (the options are +/- 100, 250 and 500 kHZ) I havn't got a handle on just yet.. so wich 8000 model Im not quite positve on just yet.. the lower noise temperature (less then 25K is what Ive been looking for, thats what the dish size charts are based on) basicly makes it like you have a larger dish so thats always good..
I havnt seen the retail price on all the availble options, I would like the choice but if someone that knows better could clear this up for me I would be greatfull.

If someone knows of some other alternatives that would be great..

some good Ku LNB recomendations would be nice as well..

and sorry for the messy post Sadoun.. I hope you can gather something out of my ramblings here.

superhempt 15 to 17 degree range are good also cal amp same range is good and dependable{i've been using the cal amp for 12 years no problems} same brands in ku at .07 to.05 range. also may be stock some acuator arm covers. :mozilla_smile:

[greenmaji]

cal amps C-band LNB's are listed under there commersial product line.

rainman. is this something like your LNB?
http://www.calamp.com/pro_comm_140105-1.html
the stability is only +/- 500kHZ.. If thats the case then 500kHZ it is.. :mozilla_laughing:

and I am googling and I can't seem to find the OEM's site for superhemt..

[rainman]

it looks the same but i don't have the commerical grade lnb.mine is a 25 degree. :mozilla_smile:

[greenmaji]

It appears that cal amp has discontinued C-band supplies for consumer use from looking at there website, the consumer products seem to be for the normal Ku dishes/lnb's and such.

Does anyone know the manifactures of BUD's, I would like to look them up and see if they have polar mounting supplies and parts that could be sold. :mozilla_wink:

yes, I have alot of free surfing time.. Im also reaserching building a nice desktop rig, otherwise I would be hitting the net harder for this discussion.

Great suggestions, keep it on.

A C/Ku LNBF woulb be nice for the mini-BUD guys.

Another vote here for Norsat LNBs.

When I installed mine I picked up my ribbon cable on ebay for lack of anyplace else even selling it. It was tough pickings!

You might be able to partner with NPS or the like on 922 sales / programming promotions.

Ive been using a 5ft dish for both my C & Ku band for years and does a good job. No I cant get some of the birds way down in the horizon, but not much needed out there to see.

But then again, when your in Texas, well we got it pretty easy shooting east to west birds. And now with all the FTA stuff, even the 3ft Disque motorized dish does the trick. But still a lot of good feeds on C-band. Just gotta scan for them.

8.5' is the smallest I would go, you may lock feeds with a smaller reflector though I would not recommend it, I would not see you locking the 4dtv guide or HBO/MAX on a dish of that size.

when dealing with c band signals yes like tdti1 stated i wouldn't use any thing smaller then 8.5 ft dish for c band.

The 8.5' recomendation is too general, it depends on were you live and the EIRP of the birds your intrested in.
Uhh.. in KY all the DVB C-band FTA is 41+..
check the chart.. (this chart assumes a 25 degree LNB in normal db orentation ie with elbow)

I dont know what the signal strength is for digicyperII FTA but I couldn't care less about 4dtv's HBO/MAX bird so as far as I know, I dont need a 8.5' dish.
so far as my calculations go I will get a strong lock on everything Im intrested in so far with a 6' dish (poor conditions and will deflect stray signals), and a digital lock on clear days with MUCH less.

to be honest.. If I took the elbows off the feedhorn (making the feedhorn cover un-usable), used a 15 degree C-band LNB with good stabilization, RG11 feed in.. Id most likely get my FTA DVB channel on a 1m dish on bad days 1m is the legal limit my landlord could impose on me, it would be one ugly dish but I would think it looks L33+

so to get everthing 4dtv has to offer, yes.. you need a 8.5' dish..
but FTA DVB in the KY? NO!
FTA digiscyperII in the KY? someone clue me in on the signal streagth in the KY and I would be a happy camper.. (If its more then 40, Im going to be thrilled )

anyway to make this post more usefull
What company produced your BUD (the actuall dish) 4dtv/C-band guys?

[rainman]

my dish is a orditron sx 8.5 feet with 25 degree cal amp c band lnb and .07 cal amp ku lnb. we are not saying you can't receive a signal with a smaller dish just that the picture quality is better with a larger dish. most of ky is in the 41 range for most sats.

[vj9999]

EIRP is important of course, but the reason bigger is better is because with smaller dishes beamwidth is too wide and alot of signal gets spilled over from adjecent sats.

[greenmaji]

(side note: that leads me to belive you could stack smaller dishes and use equal sized feed lines to connect multiple dishes together to get a more narrow reciving beam.. but that's just my brain going off somewere silly, it would require too much $$ to be practical)

and by that illistation a dish just over 1M can narrow it down to 4 total degrees

Ahh yes.. but that tells me nothing about the minumum size dish needed for just FTA feeds.

8.5' is recomended for HBO/MAX because the sats. are very close together.

What FTA feeds are as demanding as that? from what Ive read, there are none.

that leads me to question what FTA feeds are the most demanding, and then do I care about those. (if its something like the NASA channel I could do without it)

any more BUD dish brands (thanks rainman, have you checked out there site for supplies yet?)

[rainman]

yes i've been on their sight they team up with KTI. i don't think they make the 8.5 any more.

I don't think there is a definite answer to this. If the feed is on the satellite that has no satellite to it's left and right that has a signal on the same/approximate frequency then even 5' dish would be just fine.
