Channel master 1.8M Dish

[CROSSBONES]

At last I have installed it!

The pole is concreted three foot into the ground. I have also filled the pole with concrete. I have added 18" T&K`s for extra support.

I have a few fine adjustments to make to the mount as it is pulling in most of 7w H`s.

I have given it a scrub, but will do a better job when i have more time.

nice one, the neighbours don't mind then

how far east and west can you go to ?

did you lift it up yourself on the mount as bet they are quite heavy

[CROSSBONES]

I did get a comment from one side, saying "thats big!"

It is quite high up though. I have not gone beyond 30w, as the jack is not strong enough, as it struggles to bring the dish back.

I think ill have to invest in a heavy duty actuator.

It took me and my gym buddie my eldest son, and two of his mates to raise it up. It weighs a ton!

[wod]

so you didn't go for the worlds strongest man dish lifting event then lol

on a smaller note i will be doing mine soon but its nothing in comparison to that dish

[Rd100]

So you receive nilesat at 7'w fine so what signal levels are you getting and can you receive eurobird 2 at 25.5 east? hopefully you might as you are only about 50 miles west of me

[CROSSBONES]

yes i do receive it, im getting

SNR 68%
AGR 52%

there is a good majority that I dont pull in on that bird.
what about you?

[kimbo]

Nice dish mate - please let us know how you get on with Nilesat and other birds.

[deepbluesky]

What a beautiful dish

I am surprised that you get Eurobird 2 at all.

Further on i am curious if you get anything of 42E East Beam, 39E S2 Beam and 7W Atlantic Bird 4.

Could you please write down the received frequencies ?

[don'tknowdon'taskme]

that looks the boll%^ks m8 also re-doing my setup, a 24in heavy duty actuator is a must too.

[Prodelin]

Try NTV+ on 36East.

[Rd100]

Is that just nilesat or euro bird 25.5east?

yes i do receive it, im getting

SNR 68%
AGR 52%

there is a good majority that I dont pull in on that bird.
what about you?

[PJ02]

Glad to see you've finally got it up Crossbones.

[wod]

have you tweaked the dish more and do you get 7west any better ?

[CROSSBONES]

Its going to have to come down, for me to make the adjustments

[satsid]

looks like a 1.2 that dish lol

[Nachmany]

Nice works !
Enjoy with your new System.
Also, I have Channel Master 1.8m with polar mount.
This is great dish, And the top of the dishs.

Did you ever get it back up???

[CROSSBONES]

Nope sold it now.

[GreenmanBelg]

Nope sold it now.

Well thats it, any regrets?

Asked somewhere else over the positioning of the feedhorn, mine is fitted so none of the rings are showing, RD100 says one ring should be exposed.
Any views?

Thanks.

Moved it as RD100 said as per Andrew instructions and no change.

Well at least its correct no.

[CROSSBONES]

Yes I am sorry that I sold it. But got a good price for it so that made it a little easier

I tried it in various positions but the position in the pics above gave the best results.

Rd100 also tested an lnbf with better results than the matched feed.

Have you given that a go?

[pedro2000uk]

That's what we've found.... use longer neck lnbfs or expect to extend most lnbf's focal point in about 10mm ish' to match the longer wave guide/ feed horn on the c120 + feed horn to get the most out of an lnbf.

So Pedro are you saying feedhorns plus are a waste of money?

Which normal LNB was best?

Must get my second CM 1.2m outside to test.

hi

hope you dont mind my chipping in here -
as a c.m. 1.8 owner i,v been following this thread --
out of curiosity -- a couple of months back i tried 2 lnb,fs on the dish instead of the matched feed -- which has an Inverto twin - C-120 on it

i din,t do extensive tests -- just the one transponder on nilesat
11862 V 27500 - city 7 tv --which here in the north west of england is a weak to medium strength transponder , depending on weather

i used a darkgold 0.1
and a Sharp white case -BS1R6EL 0.3

the sharp was 1 % less signal than the matched feed
the dark gold was equal to the matched feed .

i also have a 1.00 metre channel master -- i,v tried 4 - different l.nbf,s on that dish , and all have slightly out performed the inverto/ matched feed

i think its a case of - modern lnbf,s-- have improved a great deal in the last couple of years .

i hope this info is usefull to you

Thats very interesting. Maybe there should be a sub forum devoted the CM's, feedhorns and the rest.

If the weather is OK tomorrow. I'll be out testing my second CM 1.2m.

Will keep you posted.
