when trees might be getting in our way, it's a good idea to understand exactly how high they are today,
knowing that they'll keep growing... you can google numerous ways of measuring the height of an unknown tree, but here is one.
https://en.wikipedia.org/wiki/Tree_height_measurement

Another important tool for sighting a proposed dish location is to use something like dishpointer.com to tell you how high an obstacle can be before it becomes a Problem.
http://www.dishpointer.com/

Place the green dish at the exact location of the proposed dish location, check the show obstacles box,
move the red balloon along the green LOS line to the potential obstruction. ie trees, houses, etc.
The result will tell you at that distance how high the obstacle can be when it becomes an obstruction
to your Line of Sight to the selected satellite. Do that at a few extremes in the arc, and understand the heights of what's around you. Here in similar tight quarters, I wound up going a little higher than I normally would have when setting the pole, as well as set it back as far as I reasonably could from any obstructions.

In the example below, the building across the street in Manhattan or wherever that is, outta be lower than 53m, if I wanted to place a dish
in the center of that rooftop or I'd be blocked to 91w.

Dishpointer.com has been a great tool once I figured out exactly where my dish was in the yard. That line is pretty close to dead on. I've sighted all the birds I get without the aid of a compass just dishpointer and using hand estimates on where the next satellite should be from where I'm at.

Learned estimating degrees of arc from my AstroPhysics classes.
with arm extended toward sky
25 degrees is roughly the distance between thumb and pinky stretched as far apart as you make them,
15 degrees for index to pinky,
a fist is 10 degrees,
three middle fingers together is 5 degrees
and the pinky itself is about 1 degree

I like the switching idea but the dish`s will let you down on many signals.

is that building in post 13 your house or an apartment? It looks like it has a flat roof?

as far as not being outgoing, etc. Talk about dishes with your friends and family all the time, like ya would
the family pet... Sooner or later, someone you know may come across someone they know looking to get rid of something
and may think about you. If you don't talk, no one knows your interested other than you.

JHOLT...WITH A LITTLE CREATIVITY YOU CAN IN FACT FIT MANY DISHES IN A SMALL AREA..

BUT PLEASE...FIND A 10 FOOTER AND WORK IT IN THERE SOMEPLACE....LOL

GOOD LUCK

Yeah I know from experience for example on 103W I can't pull in the NBC mux on 11880 H 30000 and 12080 H 30000 I get high signal 85% and Quality of 40% but my X2 just won't lock. the 11760 H 30000 will lock but I have to really fine tune before it will.

 The building is my house just bought it used to belong to my grandparents. Aside from the pine its one of the tallest buildings for a while. It does have a flat roof or mostly flat the back third has a slight grade so water doesn't pool, and there is a 2-3 ft wall on the front and sides that is flat. I could mount them there but unless I motorize or go the multiple dish route might be a pain 20 years or so from now climbing up there.

pines are kinda messy, could you get out the chain saw and put up a non penetrating roof mount?

I see where majortom is going with this...Flat roof??..Many options up there.

Right now the pine is maybe 2-4 ft higher than the house so I don't think would be a problem right away. Dishpointer says the tree would have to be another 30ft higher before becoming a problem if the dish was toward the front of the house 

I'm planning on having it taken out but I've quoted as low as $500 and as high as $1000 to get completely removed.

if you ever need a new roof, consider installing a roof hatch and a ladder for easy access?
I'd be goin up there all the time, at a minimum, for OTA antenna projects etc.

And a 2nd reply from me on this.lol..I once did this using 1.0x.7 Primestars,1.0,1.2 Ch Masters parked at 15,22,30,72,83,85,87,89,91,93,95,97,99,101,103,105,113,121,123,125 and 127.It made for a very nice setup as all the dish`s were very good performers and made blindscanning so fast.Could scan all those sats within 10 minutes tops as all were tied into every receiver,computer by way of 4x8 multiswitches Going into 16x1 Diseqc switch`s.

Cutting the grass and weed eating around the poles was time consuming so I downscaled and dont regret a bit!..Now just having 4 1.2m Ch Masters.3 are parked-91,103 and 105.The 4th is motorized.All still tied into multiswitches going to every device.ALOT cleaner out in the yard and I dont miss much.Scanning is slower but much happier.

Motorized is the way to go jholt...Flat roof..Perfect.[cool]

I do have a hatch actually, you can kind of make it out in the picture so not that huge of a climb. I think I will start putting them up there. I should get most of the arc from that height
