1000.2 and 1000.4 Eastern Arc switch out LNB's

[jtoo]

Hi,

I have a 1000.4 Eastern Arc setup, the one with the 3 LNB's (61.5, 72.7 and 77). I don't get 77, never have and don't need it for locals. Anyway I'm wondering can I switch out the triple eye LNB and it's bracket for the 1000.2 dual LNB (61.5 and 72.7) without having to take the dish off, readjust skew, aizmuth etc? Would it be as simple as just unscrewing the bracket changing the eye and reconnecting the coaxial cable? Could I still use the 1000.4 dish itself with the dual? I only ask because I find the signal with triple LNB not to be very good at times and I'm thinking because the dual has bigger LNB's I could get a more reliable signal. I have friends with it who get a much better signal then I do. I'd rather not have to put in a work order with Dish and just do it myself is why I'm wondering if it's a simple procedure.

Thanks,

J

As far as I know,no you cannot. You have to use the 1000.2 Eastern Arc LNB with the 1000.2 Dish. If your 1000.4 dish & LNB is working for you as far as 61.5 & 72.7 goes,why switch it out? Let me digress,I also have Directv. Because I added a fourth DVR to my 3 DVR & 2 receiver set-up,I had to install a SWM-16 multi-switch. Well Directv is going to come out with a 13 tuner LNB,but if I want it,I'd have to undo everything I went through installing the SWM16(& suffering from heat exhaustion doing it).
Back to Dish,I have a 1000.4 Western Arc dish. Because my LOS is blocked now,& because my DMA broadcasts in Eastern Arc as well Western Arc,it would be a whole lot easier to get a 1000.4 Eastern Arc LNB & install that than to replace the whole thing with a 1000.2 Eastern Arc dish.
Save the grief & stick with what you have.

Maine, eh? I think that's why you can't pick up 77. What exactly does " not very good" mean? If your neighbors are getting better signals and they have the 1000.4 dish, I'd say yours needs repeaking.

Very northeast Maine. I only get around 25-30 on 72.7 at peak right now, 61.5 is 10-15 (grey Turbo HD triple LNB dish). Every time it rains I lose signal, however I have a neighbour with the dual LNB's (the black dish) and he gets 60-70 on 72.7, no obstructions for either of us. So I thought maybe it was the much larger LNB eyes on twin LNB dish that were making the difference. Hence why I thought I'd swap out the triple LNB for the twin one. Just take the bracket and LNB off and put the bracket from the twin one on (I have the twin LNB and bracket already) without having to pop the dish off the mast and change it all out. Or maybe the LNB itself is bad, not sure. I hate having to call a tech as my work hours make it such a nuisance (past experiences, same results) and would just like to do it myself.

 

[TheKrell]

Whoa, those are very low signals. Something is wrong with your setup. Do I understand a Dish tech was out already to fix this and failed to do so? You need a better tech!

IIRC the 1000.2 dish is smaller and has a shorter focal length than a 1000.4. Also IIRC, because of the focal length problem, the bracket on a 1000.2EA LNB assembly will not fit on the 1000.4 dish. About the only thing you can easily do is replace the 1000.4 LNB with another just like it, and see if that fixes the problem. The 1000.4 has a fine azimuth adjustment screw; you could try that as well. But my recommendation is to get a tech out again anyhow. Maybe Saturday?

I don't think that he's called a tech yet,maybe dirt can help him as far as scheduling someone to come out & look at it?

Yeah I know the tech is an option, but Id really like to do it myself, as I'd like to learn how to do it anyway. But do you actually think changing out the whole thing would make a difference in signal strength? Meaning, leave the mast, just take off the 3 LNB turbo dish and put up the black twin one. I've just seen so many stronger signals from that type of dish up here (can't buy the triple here anymore). I'd think it'd be easier point and peak at the very least. When pointing, which twin LNB is 72.7, is that the one you're to peak? I've looked and looked for the instruction manual for this particular dish on the internet but i cant find it (lost the one that came with it).

Have you tried DISH's site for instruction manual? The 1000.4 is a larger dish than the 1000.2 so it will capture more signal. The 1000.4 can be peaked to receive 61.5 & 72.7 so there is no reason to swap dishes. You can DIY or get a good DISH installer to do the work, do you have the protection plan?

We have consistently seen the EA 1000.2's get higher signals than 1000.4's. I know the K4 is larger and has better fine tuning but the K2 just does better.

 

[NYDutch]

I have two triple horn EA LNB's on hand for my 1K4's, one with individual feed horn covers, and one with a combined 72.7 & 77 feed horn cover and single 61.5 cover. The combined cover LNB gets signals that run a few points lower than the single cover LNB, but both get signals in the low to mid 50's at our cottage in Upstate NY. A neighbor with a 1K2 dish with a dual horn EA LNB gets signals in the high 40's to low 50's, no matter how much we tweak on it. Another neighbor with a 1k4 dish and triple EA LNB gets numbers similar to mine.

 

[JSheridan]

I'm basing my opinions on seeing 200+ of each in action.

 

[NYDutch]

Oh, it's certainly possible the 1K2 neighbor has a dual LNB that's not quite up to par. I'm just reporting my admittedly limited experience. I don't have another dual LNB on hand to substitute as a test.

 

[jtoo]

I can't find the instruction manual for the dual LNB anywhere, I'd just like to know which transponder I should be peaking on. If someone has the manual in PDF or can direct me to to a link to it, that would be great. I've had the local installer out in the past and Ive been told at 20-30 is the best Im going to get with the triple LNB Turbo Dish up here, but I've seen evidence of the dual LNB signal (no rain fade, etc) being so much stronger that I thought swapping it out would be wise. Looks like I'll have to change the whole thing, aside from the mast, to do so which is fine. I miss the days of the Dish 500 setup, 110 and 119, had a fantastic signal up here, but alas I could never get 129 for the HD channels.

 

[ChadT41]

21 or 13 if I remember correctly on 61.5

 

[lucky86]

I use 21

In my experience, I live in Los Angeles and have installed the Eastern Arc due to LOS issues with 129. At first I have the 1000.2 and at beast I could pick up in 15’s on 72.7 and 30’s on 61.5. With 77, I could barely get 10’s. I called my installer and asked for the 1000.4 and he said that the best dishes are the 1000.2 and he would have to special order the 1000.4 tripple lnb’s and that would cost a lot. So I went on ebay and got it myself and installed it using my meter. My readings on 1000.4 came to 40’s on 72.7 and 50’s on 61.2 and not to mention, I get 77 which I don’t need at 50’s. While tweaking, I ensured I got the most on 72.7 and then decent on 61.5. I didn’t even try for 77.


In my experience, the triple LNB combo is the way to go. But then again I’m on the west coast so I may not be a perfect test point for the eastern arc.


I’ve moved my configuration recently to 110, 119, 118.5 and 72 as a wing dish just for HD, as I realized San Diego is close by to hit on spot. My Eastern Arc 1000.4 and 1000.2 are happily sitting in my storage.


Another observation, You cannot combine the eastern arc into the western arc builtin switch. It wont pick up 72.7 unless you have the dish 300 (old style) to get just the 72.7.


In my opinion, dish should officially allow 72.7’s on the west coast as it works perfectly well.

Hi JDT,

This is just anecdotal stuff from a DIYer who was in a similar situation. My 1k4 triple LNB setup had better signals than yours, but not a lot. The techs who did the install were out a few times and could never get 72.7 higher than mid 30's and 61.5 maxed out in the low 40's. Rain fade was a problem. Like you, I have no need for 77, so I switched a few weeks ago to the 1k2 with the twin EA LNB. I relocated a new mast 3 feet away in case it all went horribly wrong. Using the receiver as the meter, the 1k2 has signal strength of 57-61 on all 61.5 and 72.7 transponders. No rain since then, but I'm impressed with the 1k2.

That said, peaking the 1k2 was frustrating and imprecise because of the lack of fine adjustment. My current tinkering project is to try the 1k4 dish with the twin EA LNB. After snipping the center bracket tab flush the twin LNB fits perfectly on the 1k4 bracket. Remains to be seen whether the 1k4 dish with the twin EA LNB (assuming it works) will actually be better. On a tripod earlier tonight I got about five points higher with this setup on 61.5. Not sure that's enough to make a practical difference on rain fade over the 1k2 signal, but at the same time it couldn't hurt.

Good luck!

Hi,

Thanks for the great info. So you just left the 1k4 dish in place, left the arm as is, did some snipping and put the 1k2 twin LNB on the dish? Basically I could climb up take the triple LNB off and put on the twin LNB one, with some snipping and Im good to go?

 

[kbell]

Unfortunately my tinkering project did not prove successful, or at least not yet. I could pull in a pretty good signal for 61.5 with the twin EA 1k2 LNB mounted on the 1k4 dish. The problem was that it wasn't seeing 72.7 at all. The two possibilities are that this configuration is physically incompatible due to length or angle of the arm on the 1k4 dish, or the LNB I was using for the test had a bad 72.7. The particular 1k2 LNB I put on the 1k4 dish was a used one that I had not tested before (not part of my working 1k2 install), so either of those possibilities is still in play. If I have a few hours this week or next I may try the test again using the twin 1k2 LNB that I know works well.
