I think the hail storm reduced my Q a little. We had hail for about an hour steady. So my question is not so much as WHO has replacements as to HOW would you install a replacement if you had one.

I am thinking that if I can remove a panel I could easily copy it with a pair of tin snips and replace it.

has anyone done that?

I have cut patch panels with heavy scissors. The mesh on the 10*ft dishes I have are held on with screws. It should be easy to fabricate a panel to replace yours.

On many dishes the mesh fits into grooves in the ribs. It is not always so easy to get them back into the tracks after removing them. Different animal than the ones which lay on top of the ribs and just get screwed down. I have spoken many '"bad words" trying to put them back into the grooves. Just saying!

On my uni-mesh I have sheet metal that has little diamond cutouts. There a some button head sheet metal screws along an arc at the outer diameter and one rib at about a half radius. It looks like I would just grab the pizza slice by the crust and pull it out. Then the new sheet metal piece would install pointy end first towards the center of the dish and seat into the grooves. Maybe get some grease to make the job easier.

Again...I am asking ....has ANYONE found a source for this material???? I will cut it.

The best thing to do is jump in the car and look for another Unimesh Dish. Replacing damaged mesh would be the absolutely last resort for me and you will never get it the same as it was before.

Looks pretty pricey..I see a lot of choices still. Not sure what was used on my dish. Especially ..

Question: How do you determine the "gauge" for instance #18 etc I assume I need to use a micrometer on the thickness? I am about to try find a table of metal gauge if there is one.

Does anyone know the original typical dimensions size of the diamond hole, and gauge?

I looked over my small fleet of metal dishes and found several different materials used a few had a flat panel sheet with round holes while others had the expanded sheet with the diamond shaped opening in the metal. (called expanded metal sheets) Some what at issue here is whether there is a desire to use the dish for Ku freqs. and of course the metal may need be proper thickness to fit back into the rib grooves. It would be easy if only one lived near the store which was selling these sheet products. Shipping costs for just one or two metal sheets could be a bit high and hard to swallow also.

We should first start over and ask if it is possible to just repair the dents or tears in the original dish panel? One of my dishes has a few small tears in the fabric glues back together. Cheap and simple to do. Not perfect but a fair way to fix only a few issues. My Unimesh got a few tears clean through from hail hits. Broke my heart as I had bought that dish new. It sits still in storage--waiting waiting waiting---perhaps it will self heal. Perhaps not.

Yeah mike for thickness, you could use small drill bits to measure the openings in the mesh. Some Unimesh were expanded sheet, mine is and it sounds like yours is. Some were perforated sheet, so round holes in those.

how many panels are you talking about being damaged?..

I have the 10 foot Unimesh sat dish which has 4 separate panels all welded up of separate ribs and then there are in each of these 4 panels more each mesh inlays with the diamond expanded design. 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.

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.
