Mega tvi: What is the best switch setup for 5 Legacy dual lnb's 82/91 110/119 & 129.

[tOr0nTo]

With other hd receivers I have used, a 4 port disecq with an sw21 switch exiting one of the ports on the disecq worked... okay... but my new Mega tv1 seems a more finicky beast: I have tried several combo's of Disecq 4 port, Sw21 switch, A/B switch with 2 cables, & also researched previous threads in the 'switch discussions and pictures' section of this site with limited success.

Long Story Short:

Should I buy a Disecq with 8 ports? First I'm asking if anyone has had success with some combo of 4 port Disecq, & switches of some sort or other.

OK, 5 legacy LNB's will need 2 coaxes per LNB.

Unless your talking about a DP single LNB with dual outputs.

If they are ALL DP singles then a 8x1 Diseqc switch will work, but your receiver needs to be Diseqc 1.1 compatible.

If they are truly the old style legacy LNB's (+13 and +18 volt switching) then you will need a switch with 10 inputs, 2 inputs per LNB, one input marked +13V and one input marked +18V per LNB.

EMP makes such a switch.

But if they are like the DP single LNB's (or are DP single LNB's) then a Diseqc 1.1 or 2.0 8x1 switch would be the way to go.

Each lnb has two coaxial outputs. THey're all about 10 years old. They have Dish Network on the casings. Pretty common eqpt. I'm honestly not sure if they are legacy but in my scan settings, lnb type, only OCS_DP works. I took pics of them & will pm to you if needed. The dishes say ' Dish Network 500' on both of them. oval dishes about 2' wide max, with 2 lnb's each.

THe Lnb's have 'Dish digital lnbf' on them, does the L stand for Legacy? I donno. From what you wrote, I'm inclined to think I need an 8x1 switch, but can you get closer to confirming that? Sorry I haven't posted pics, I haven't found how to do that either here or in a pm.

Here's a pic of one of the lnb's, they're all the same.22764

Well that photo is too blurry to see the LNB labels correctly.

Any way to get a better look?

And if the LNB looks to be as old as I think it is, you may be better off to get all new LNB's, something like this one.

I took them last night in the dark. I will now go up & take pics over. They are all similar: same shape & "Dish digital LNBF".

[tOr0nTo]

My camera battery is dead. New pics will have to wait.

I wouldn't want to replace them unless I was certain something was broken with them. They do give hd, & from what I know, have nothing that tends to wear out quickly. The ports are not rusted- it has the usual plastic housing.

Meanwhile I will try to find a pic of an exact model on the net. 'Dishpro' look similar but I don't see dishpro written anywhere.

That LNB from what I can see maybe an old legacy, you would need a switch that can run that type of LNB, you would need a legacy switch with 10 inputs, the only one I can think of is an EMP.

It also could be the old style standard LNB, then the 8x1 switch will work fine.

One way to test this is to hook up the one for 110 directly to the receiver and see if you get all the transponders, if you do then its the standard type, if you only get the H or V (L or R) transpondres then its the old legacy type, it then would be better to replace them all, the EMP 10 LNB swithc is a bit costly.

Look at this one.

Thanks so much. I'm gonna wait 30 min for my camera to charge up, take some pics & will also do a direct connection to 110 & figure it out soon.

Sadly my camera does not have macro but believe me, all 5 are the same- they say 'Dish digital LNBF' followed by a model # & made in usa or japan. All 2nd hand when I bought 'em but work fine.

Hooked up the 110, 99% Q. It's both h & v's, you might be able to surmise enough from this short list, if you need more let me know.

1 12224 v 2 12239 h 3 12253 v 4 12268 h 5 12268 h 6 12268 h 7 12282 v 8 12297 h 9 12311 v 10 12326 h

not sure why both ports need to be hooked up
have used legacy for years and never had an issue only using 1 port per receiver/switch setup

I've inquired on here & elsewhere & it's perplexing the range of recommendations, from just replace the sw21 with a $4 22mhz switch to replacing everything: dishes, 5 lnb's, switches, the whole kit n' kiboodle lol

Anyway the pic I attached in my last message should give a good indication of what lnb's I have.

It depends on how old the legacy LNB's are, the really old ones needed to have both outputs hooked into a combiner then to one receiver, for more then one receiver and more then one satellite you need a switch with 2 ports per LNB, SAT A +13 and +18, SAT B +13 and +18, then two or more receivers can be used.

The newer legacy LNB's can use one port to a 4x1 switch to one receiver, they call these types a "Standard" LNB, when more then two or receivers are used a SW34 or SW44 or SW64 legacy switch was used, this had the SAT A, +13 and +18, SAT B single input switching ports for the SW34, and the SAT A, +13 and +18, SAT B +13 and +18 switching ports for the SW44, and the SAT A, +13 and +18, SAT B, +13 and +18 SAT C, +13 and +18 switching ports for the SW64.

All this went away with the bandstacking LNB's used today.

After looking at the new photos it looks like he has the band stacking type of LNB, that's why the OCS-DP setting works, for 5 LNB's the 1x8 Diseqc switch will work.

Cool. So I should fogedabout replacing the sw21's with 24khz & just go with an 8x1.

Could be my last q for you: Would it be okay to use two 8x1's, each connected to alternate ports for each lnb, to go to a separate receiver in my kitchen? Would that present power up issues with the Mega tvi? I would never have both receivers on at the same time if that was a bad idea.
