best way to wall mount cm 1.2 dish ?

[wod]

I have just got hold of a channel master 1.2m dish and would like to upgrade from my current setup but doubt the wall mount is strong enough

currently have 90cm fibreglass channel master dish on jaeger 1224 motor which is sat on set of 24" inch t&k brackets, 3inch pole.

will fitting the cm 1.2 be pushing it ?

was thinking of using a flat roof mount as there is a very solid flat roof below but problem is height of the poles on these can I extend them past 1metre high as i will need to raise it to help clear some trees as 2 metre high flat roof and then 1.5m should be enough.

pic of how dish is now, is below.

I just want to make sure it will be safe in strong winds as the dish is massive in size

Don't know ifyou can still get the Channel Master Tri-Mast wall/ground stand still, that's a heavy-duty 3" mount. I use one as a ground stand.

A NPRM might do well there.

Terrible May weather isn't it Wod ;)

The new dish will have a wind loading of about twice the 90cm. You will need to move the pole off the house by another 20 cms if you want the same arc coverage, or raise the pole up another 60cms or so. I would suggest adding two more T and K's to the wall and lift the whole thing up.

The pole looks substantial enough, so if nothing is moving at the moment, then you should be OK.

yes that is an old picture i have.

anyway the arc of the dish in the picture goes 23east to 58west. i'm hoping to increase this to 39east, will i get mbc on 26e with the 1.2m ?

i have thought of dropping the dish lower and using 36" t&k but will that be enough ?

a roof mount i was hoping would work and extend the pole and use some lashing wire to stop it taking off in strong winds

hi - i,m in n.w yorks -- 1.2 channel master is fine for MBC -- even in bad weather --

Dropping it down may cause trouble to the far West with the house next door, plus 36 T/Ks may give a bit more movement than four of the ones you already have.

Unless you have trouble with neighbours, I would raise the mount slightly.

 

[wod]

no trouble with neighbours but there might be if the 1.2 goes up on the wall, as it is larger then current dish which is up and to the west the house is ok as it is well past 60degrees west.

i'm just keeping a look out for a non pentrating mount as i might just up the current dish and stick the 1.2 in the garden for something west 1/4 or 7west if i could receive verticals to have a play with.

Is the roof good enough to cope with a static 180 odd kilos ?

I would add 2 more K brackets on to original setup and raise the dish up slightly? Are you going to be using an actuator arm?

 

[satelliteman]

Guess he'll be using the current 1224 motor, ...Wod?

yes the roof is solid concrete as its an outhouse thing, not sure why they was made like this in the 1970s used to be council houses but all estate bought now I think.

yes I will be using 1224 motor.

got home from work and had a look today, I can put the dish on side of house but the area is very open and people can see it.

my mistake was I didn't realise how large 1.2metre is, well only paid 50 for it so not wasted a lot of money if its not used.

 

[wod]

well going back to this i've decided not to use the 1.2 and I have lifted up current setup which is cm 90cm with 1224 motor above the gutter and I can now get around to 42east, originally only could get to 23e.

In the process I think i've damaged one of my arms, due to trying to save time and lifting the whole motor + dish up the ladder and on to the pole in one go, stupid I know

does this look safe, as I'm going to buy another set of 24" brackets. I was thinking to add a t just below the gutter to hold the pole in case of movement in windy weather.

the first bracket is 5 brick courses down the wall.

 

[Channel Hopper]

Add one more K at the top and all should be fine, a T would only secure at the top course and they are rarely as well mortared as the ones further down.

Only you would know how well the existing bolts have remained secure, though a quick half turn of all of them wouldn't go amiss.

Wod, I hope this was one of the LNB support arms (which are replaceable) and not one of your limbs (which are not)

I was going to put the t, 3rd course down, as you say the top course might not be solid. I just want to make sure the pole wont move about as its 4ft above the top bracket.

sonnetpete, yes it was one of my arms that I hurt not the dish but its fine today.

I would leave at least 5 brick course from the eaves as it could lift your mortar joints, any less with wind factor i would not expose above roof if you can help it, and go for 36in t & k 3 of ,which should bring it out enough from the wall

Use the 'K' as you will have one spare. You could then get away with the second course down as you will have the fifth course tied to it with the bracket.

 

[satelliteman]

Won't a 'K' take you too far up towards the eaves. I'd be inclined to fit a 'T' 3rd course down.

yes that was what I was thinking, as is it really safe to mount to the first course of brick work at the top ?

what I was going to do is put a t on the 3rd course and change the bottom t bracket with a k bracket which I hope would stiffen the mounting up

so I would have
t
k
k
