Big Dish Pictures!

[PSB]

I had an install to do round the corner from this cable companies down-link facility and just had to stop and have a closer look, these dish were 10-15' across! Hey they almost have as many dish as Iceberg!

sweet!!

I've got to take pictures of my antenna farm one of these days

I'll eventually have a big dish one of these days I'd like a solid dish cause they look cool, but I'll probably be going with a mesh.

Nice pics

Bigger Is Better : )

Those are Andrew dishes, high quality stuff.

Kool dish farm PSB!!!

Now you are gonna have to answer a whole bunch of FTA questions cause you are FTA king!

Bad choice, mesh dishes don't pick up Ku signals that good. Spun aluminum is your best bet.

I agree with Diamond Jim,

I worked in a little cable system on a dish a couple of weeks ago trying to pull in the HITS transponders on G4R on an aluminum dish and for kicks we switched things over to a mesh dish and looked at the signals on the spectrum analyzer. The mesh dish showed considerably more noise although the carriers were relatively at the same level as the spun aluminum dish we were comparing it to.

I wish I has taken the cable along with me so I could have of saved some screen shots of my findings.

Someone correct me if I am wrong but I believe at the Ku band wavelength less signal is reflected back toward the focal point of the dish. Also mesh dishes are made in sections or petals and are not as perfect of a dish shape as one made out of 1 big sheet of aluminum.

With Ku Band, the bandwith it a lot narrower than C Band thus causing it to go right through the mesh instead of being directly in to the feedhorn.

If I had a choice to get a dish I'd rather have a professional solid dish, but I can't seem to find one.

take a trip through a sprwling rural area.

They are out there a lot of them. It doesn't have to be spun aluminum it can be a fiberglass dish.

On a side note if I scan it I will post a spun stainless steel dish that I saw in Wisconsin. I know a guy who used to install them and he said they had to paint them flat black because the mirror like surface reflected so munch heat that it would literally burn up LNB's.

My farm pics are in the You might be a SatelliteGuy post....

 

[Mr Tony]

just added a 6th dish over the weekend

Got a DirectPC dish (thanks Pete!!) and have it installed for G3...North Dakota Hockey & Football

I know a guy who used to install them and he said they had to paint them flat black because the mirror like surface reflected so munch heat that it would literally burn up LNB's.

That is true. During March and October the sun aligns it's self at a ceratin angle and the heat rays reflect off the satellite to the dish causing big time heat. It starts about noon on the eastern satellites and moves west disrupting the the signals for about 15 minutes per satellite. I have never had a problem with melting LNBs and feedhorns, I think it's because of my location, but I have seen pictures of ones that were melted to the core. I do move the dish to the first satellite to the East of the one I am watching, just as a precaution.
