Plant a pole, a dish will grow...

    Contemplating the best location for my BUD, and at the same time considering a good location for a motorized Ku dish in my yard. The picture below is a screen shot from Google Earth using the DishPointer sat aiming lines showing possible locations for my BUD on the right (west), and a Ku dish on the left (east).

    Ku_BUD_Locations1.jpg

    The positions indicated should allow the BUD to see over the trees from 72W to 111.1W, and the Ku from 87W to 125W. This is kind of a visual example of why I've been pondering a 125W dedicated dish. There is a big chunk of wasteland in the arc on a motorized Ku below 125W that would mean I can't locate my dish in a position where I can be sure I will get anything below 87W.

    The Ku location in the picture may allow me to hit some birds below 87, but I'm not absolutely sure about my distance and height to clear the closest trees given the declining elevation as I move east. I've gone through all the various lists of known 24/7 signals I might be interested in and these sats look like they will serve our needs. The "wild" card is whether I am really giving up anything else worth hitting if I used these locations.

    The tree shadows between the lines are ~75 foot poplars that will be coming down, similar height as the tallest parts of the surrounding canopy on the south and west sides of the picture. Those shadows also indicate the boundary of my property with my neighbour to the south. I have no control over any other vegetation that I am attempting to work around by choosing these dish positions.

    Any thoughts about the area of the sky I would be scanning with Ku or C-band given the physical constraints I have to deal with?

    Too bad that the satellites are not visible..:).. There are modern cellphones which show satellites' locations, but watching the Moon on certain days can also provide information. If you can get familiar with U.S. navy site which provides co-ordinates (altitude and azimuth) of Sun and Moon for every minute of every day, you could find out if these trees are an obstacle for certain position of your pole. The Sun can help only 2 times in a year, but Moon -50 times, usually every 2 weeks.

    You mention the cell phone app but don't really indicate why you are not using one. The best one for Android in my opinion is "Satellite AR"... and it's free.

    If you load "All Active Satellites" it will show the geostationary belt in detail. There is no guessing at all. It uses the camera function and overlays the satellites over the image. You can see *exactly* if a tree or house or any other obstruction is in the way. You can also chose specific satellites and see where they lay in the image as well.

    Thanks gents,

    I think there is some confusion about what I am asking due to imprecise use of language in my post. The location in the picture is 3 hours away from where I am right now, and intend to check things out in greater detail next weekend.

    I probably should have said, "I'm not absolutely sure about my distance and height to clear the closest trees on the east end of the Ku arc at the moment given the declining elevation as I move east." For example, no matter where I was to place a dish in the yard, 72W is at an 18.2 degree elevation from my physical location.

    I've taken a few shots of the horizon from different locations in the yard choosing positions that work well for specific sats that are of interest to me. I've been using Theodolite on my iPhone because I have read different things about the quality and accuracy of the Dishpointer virtual reality app. Also, the Dishpointer iOS app has not been updated in a very, very long time.

    Selecting specific sats that I care about has lead me to believe that locating two motorized dishes at the locations shown will cover most of what I need to reach. I have not worked my way completely along the north edge of my property scanning the entire arc.

    So, perhaps a better more specific question would be - if you could only sweep 40 degrees of the arc with either a Ku or C-band dish, what sats would you cover?

    Great question but highly dependent on what you like for programming. Me? I would center that 40 degrees on 99w. I watch on c band 58, 91, 99, 101, and 105 the most (i.e., NHK, Reelz, KBRK & ABC feeds, and NBC feeds). For Ku I like 83, 101, 121 and 125 the most (I.e., TuffTV, Pentagon Channel, Velocity and the PBS feeds).

    So, to answer the question really you need to determine what you want to watch regularly vs. occasionally.

    Agree with MrBarrett, figure out which birds you like best, or will like best during the coming football season, basketball season, etc, and center your 40degree swath on the middle. Of course I like the "however many dishes its gonna take to cover it all" approach better! I've got to get busy with the chain saw around here also, dang trees keep growing taller and fuzzing out some of my view. This year it seems to be not just the end of the arc, but now even the middle-my dedicated 103W ku dish is getting less signal than last year due to foliage.
