    How many dishes do you have--HD?

    Four dishes: Dish 1000+: 110, 118, 119 & 129 (HD) Dish 500: 61.5 (Voom-HD) Fortec Star 90 cm: 91 & 82 (Bell ExpressVu HD) Fortec Star 100 cm: Motorized (HH-120) for FTA, but no HD wild feeds seen yet! ;)

    Anyone making a spring FTA "to do list"?

    In between all the rain, I'm actually doing my list. In the last week, I've updated one dish from 24" to 90cm, moved from a Dish 500 to a Dish 1000+ (adding two new LNBs), have added two more DPP44s to support 8 Dish receivers + 4 FTAs, and will next be upgrading my motorized dish from an...

    Dish Order Mixup: My Fault, Not Sadoun's!

    Hi, Sadoun! I thought I'd already posted this, but obviously missed hitting the Post key! Please accept my sincere apologies for the misunderstanding - I'd never before encountered a drop-ship situation such as this one, and I was genuinely confused about where that package came from. As you...

    Offset LNBs: Theory & Practice

    Hi, Guys! If other folks try this out, please post your results here! If indeed this formula works out well enough, an interesting possibility comes up: you could reverse the formula as a means of measuring the focal length of any unknown dish. You'd want to be careful to measure accurately...

    Offset LNBs: Theory & Practice

    Hi, Anole! Many thanks for the excellent advice - I've revised the first post to include west/east, and have posted in both of the threads you mentioned (at least I think I posted in the right threads ;) ). Thanks again! Best Wishes! Mark

    Adding 110 to 119 on same Dish

    Hi, Howard! Recently, we've come up with a new solution to the offset LNB problem that appears to give very accurate results, as posted in Offset LNBs: Theory and Practice. I'd be happy to compute the offsets for you, if you'd like. To do so, I just need three numbers: your latitude and...

    "Dish 500" out of a True-Focus 1.8M?

    Hi, SForgue! I've made some progress on coming up with a more accurate formula for estimating offset LNB positions. Based on your zip code, the sat calculator I'm using says that the satellites are at: 119: Azimuth 149.17 - Elevation 13.58 110: Azimuth 139.83 - Elevation 11.28 The formula is...

    Offset LNBs: Theory & Practice

    Hi, Gang! As an interesting observation, when I say left/right or up/down motion, that's exactly what I mean. In the tests above, my motorized dish was practically laying on its side due to the very low elevation of the 82 degree satellite here. No matter which way your dish is oriented, the...

    Offset LNBs: Theory & Practice

    Eureka! It Really Works!!! Hi, Folks! Yippee! It really works! There's just one small caveat: I had the sign bit wrong on the left/right correction. :o How I tested this was to rest the LNB on an old speaker with a varying pile of books on it, and placed this next to my motorized 80cm...

    Dish 1000 plus help please

    Hi, RWJGA! I've just finished installing a new Dish 1000+ setup, and I have exactly the same message (though it's in orange on my ViP 622). However, I believe that this is a normal message! With DishPro+ twin LNBs, they include an integrated switch, so they are capable of manipulating their...

    Offset LNBs: Theory & Practice

    Hi, Anole! Thanks for the very nice post! Unfortunately, it's raining again, and we're scheduled for three more days of rain before we get a break. I'm tired enough of being held back, though, that I may just risk dragging out the FTA receiver and the TV today if we get a short break. I may...

    Offset LNBs: Theory & Practice

    Hi, Anole! Let's use your example where I aim the dish halfway between the satellites. Only this time, we'll go after 119 and 129. As a result, we'll aim at a hypothetical satellite at the "124 orbital location", splitting the 10 degree difference. For my location (zip code 94306, in what is...

    Offset LNBs: Theory & Practice

    Hi, Bob! Exactly! In fact, in the example I gave for 110 and 119 from my home, the azimuth angle is a whopping (174.9 - 160.5) = 14.4 degrees, and from Acapulco, it'd be 18.5 degrees, even though the satellites are "only 9 degrees apart". The error keeps getting bigger as you go further south...

    Offset LNBs: Theory & Practice

    Hi, Anole! I don't know if this will help or not, but the formulas from the other thread will give perfect results if you are at the North pole (since the azimuth angle will exactly match the orbital spacing), but will yield increasing error as you head south, with a worst-case error at the...

    Offset LNBs: Theory & Practice

    Hi, Anole! I just thought of a good thought experiment that'll prove that this is a more accurate method. Imagine that you are on the equator itself. The original technique would still recommend a horizontal offset of focal_length*sin(9), but the right answer is 0, which this approach will...

    Offset LNBs: Theory & Practice

    Hi, Anole! To restate the difference in methods in a different way, the original approach used a fixed value of 9 degrees, which was the difference in orbital positions. However, for most folks and most pairs of satellites, the angular difference between the two satellites won't match the...

    Offset LNBs: Theory & Practice

    Hi, Anole! It was very easy to understand and extremely helpful, and I thank you again for it! The assumptions that I'm making here are identical, except that I believe that the original calculations ignored the actual delta azimuth and elevation, which I use here. I may well be mistaken, but...

    Offset LNBs: Theory & Practice

    Hi, Folks! To be clear, please note that I keep saying "approximation"! No matter what you calculate, it's important to be able to tweak things for maximum signal, no matter what the numbers say. My goal with this thread is just to be able to get as close as possible to the correct position...

    Offset LNBs: Theory & Practice

    Hi, Folks! I'm in the process of setting up a second LNB on a 90cm dish, and thought that it would be worthwhile creating a thread that seeks to understand both the theory and practice behind adding additional LNBs to a dish. For folks that aren't familiar with this, the goal of doing so is to...

    "Dish 500" out of a True-Focus 1.8M?

    Hi, Anole! Well, I'm the kind of guy that seeks to understand both the theory and the practice. I'll be experimenting with this today, at the same time that I'll seek to better understand the math. I've made some progress, and have come up with a better position approximation than that shown...

    Hi, Anole! I've changed the thread title to "Dish Order Mixup: My Fault, Not Sadoun's!". Since I can't change the external view of the thread title myself, I've asked Scott if he would consider changing it to match the internal thread title. Cheers!

    Dish Order Mixup: My Fault, Not Sadoun's!

    Hi, MotleyFool! Yeah, that was my original goal, but it seemed strange that that would leave the 91 LNB physically below the bottom of the dish. After reading up on other offset dish setups, though, it turns out this isn't all that weird after all. So, yes, I'll be setting it up with 82 at...

    Dish Order Mixup: My Fault, Not Sadoun's!

    Hi, Folks! You're not gonna' believe what actually happened! As it turned out, when I decided to upgrade my satellite dish setup, I kind of went hog wild and decided to increase the size of all of my dishes. So, I went off to ebay, found the best prices, and wound up ordering a Dish 1000 Plus...
