All of this is all made from aluminum.  A total of 16 mesh panels measuring about 5 feet long each by 23.5 inches wide at the outer end tapering down in the pie shape to less than 3 inches.

Among my many tools here is an older Brown and Sharpe measuring device which reads down to .001 inches thick. One of my expanded mesh panel sheets has been removed for several years because of a snow and or wind issues which pulled it out of one side and after some stress on my part I removed it completely and stored it in the garage.

Again today as I have in the past I see the expanded metal sheet at a thickness of .040 inches. The groove from where it has come out from is a bit harder to get a fair reading but I believe that groove measures at no less than .060 inches wide. I should dig out my feeler gauges as they will give a better reading.(my feeler gauges are sleeping in this morning and refuse to come out of their hiding place)

I went through the personal mental stress of my once new 10 foot mesh dish now has several dents and a couple tears in this covering. After now finding and installing 3 11.7 foot glass sat dishes with an average cost of $33.33 per dish plus the additional cost for each pole in a hole in cement I find it is not worth much to repair a lesser and smaller dish. Your results may  be different.

I have plans this summer to repair and put back up some of my mesh dishes. However with 6 large solid dishes now up and wired to the house I see little reason to spend very much time or money on the lesser mesh dish fleet. I am thinking more of a display of the good, the bad, and the ugly dish farm members. I call my solid dishes with new paint the good dishes. The ugly dishes are the ones with dents and missing panels. My solid dishes stand up well to wind and snow and hail. The mesh dishes will continue to get more damage every time we get more hail. I see little value in repairing over and over the weak and humble mesh dishes. I prefer to put my time and effort into collecting more of the good solid dishes.

For my time and money I find installing a larger dish which costs me less money a better deal. Others may see the issue differently. How much money can one throw at a dish which may get damaged again next month in another hail storm? I got no where from my house insurance company at the hail denting time so I soon got a different insurance company.

I squirt the grooves with WD40, to clean & lubricate, before attempting to replace a mesh panel.

Mine is also 4 parts, each with 4 mesh sections slid into the grooves and screwed down. I think these were by far the most common, I've only ever seen the perforated aluminum Unimesh once.

Yes I remember getting the rest of the lichen off of it. It has diamond expanded aluminum that is .040". I started to remove a panel last night and measured the gauge. I can see that the way it was assembled and welded makes for VERY difficult maintenance / repair. Unless I can find something lighter and more compliant.
Like heavy screen?

I have bad margin now things that were 70's -80's Q Are now 58. Just above the go no go threshold.

So YES please help me find a dish

Kosmo in the last month we've had a few monster storms roll thru our area...

with Hail there's been some really HIGH winds....speeds up over 60mph at times.

are you 100% sure that dish hasn't been JIGGLED and is just OFF the mark one way or another?

could be a tad high or low on elevation....maybe the dish mounting collar just needs to be spun,
clockwise or counter clockwise on the pole.....
could be small adjustments in several directions........

your current signal that close it wouldn't take much to drop a little.

i'd go out to the dish with a receiver and a tv and check closely...

might get lucky.

i fine tune mine all the time...
sometimes i'lli lean on mine...pull left or right on edge of dish...
.....manually lift up the dish or pull
down maybe while watching the tv screen....

just a thought

The dish panels have enough hail hits that some panels have slid out and belly-ed out and the great number of pock marks should be causing a lot of out phase signals. I don't think wind ALSO because I have a secluded back yard with a VERY high fence all way round. My anemometer got destroyed and I have parts on the way for that..but it NEVER measures anywhere close to prevailing winds that it would see if mounted in an open field...however I have an idea on how to fix the dish

Thank you for the specs sheet!! It gave me an IDEA!

I wonder IF the 1"by 1.25" extruded Press Locked Rib covers can be removed with a putty knife or simiilar? I envision something that is 'T' shaped and is press fit into a slot in the Radials? If those can be removed it should be SIMPLE to replace the panels.

Anyone done this? Don't tell me they break. (see where it says T-6?) They're mentioned twice.

I think if you shop for "heavy window screen" where these people live you will find the kind of material that will stand up to large hail. Even on my dishes which have the flat metal sheets with the small round holes there is some hail dents showing up.

Kosmo, try moving your LNBF around a little also. One of our huge hail stones might have knocked it off center.

Does yours not have screws in the mesh, just press lock ribs? I think those grooves that my mesh slides into is all part of the structure, made as a single extrusion. According to this mine is a 10AS, not the 10AL mentioned in that picture I had. http://www.bigdish.info/mainten/lfocal.html

10 foot Unimesh Perf. Repaired hole. (One of 3) Hail dings were gently massaged flat with a body hammer and dolly. Panels were NOT knocked out of the tracks on mine though. Hail dings were minimal. I may remove the stitching some day and solder the tears..but it performs well as is. Only touched up damaged areas with paint.May spray the whole dish later...or not. [biggrin]

Fellow Members, your posts are welcome here! Do not worry about posting everything perfect. Different receivers and LNB's will give you different Frequencies and Symbol Rates. Some set top boxes, PCI cards and USB receivers, Do Not Require all of the same information that others may need. It is not Required to post everything that others may need to tune in a feed. It is just most important to share the find. We can always adjust the Frequency and Symbol Rates and try the various Modulations and FEC's on our own receivers until we get a lock and then give a polite reply with what works for your receiver, as that information might help others as well.
