Solid dish equivalent of mesh

[highkick05]

Well you could go for a cheaper version.

Jonsa look the about the only one in the budget range in Australia far as solid go
would need to get delivered as only these sell only over east. are they a good dish though

It's also normal for cheap Chinese pressed metal dishes to warp, especially if they have had some form of impact.

Of course the signal is not affected at the edges, but if the impact has distorted the dish in any way, then it will affect performance.

Well, I don't know if it's a cheap Chinese dish. It's about 15 years old and seems sturdy, if that's any guide.

The puckers protrude outward, so aren't caused by an impact. They could have been caused by pressure applied from the back side of the dish, although I can't see why that would happen. As they would affect the parabolic shape of the dish, I had wondered if they were some sort of fine-tuning of the dish shape. However, as you guys haven't seen such a thing, I'll assume these puckers shouldn't be there and do some panel beating before restoration/assembly.

I am guessing those 'pucker' marks as you call them are the result of the Dish being either hit or dropped onto a hard surface and thats caused the deformation.

Personally unless you can see some real distortion in the actual segment I would leave it well alone unless your skilled as a Panel Beater as any attempts may cause more damage.

Whether mesh or solid a warped dish could be less then half the expected gain performance, effectively useless.

You can string the dish and check the asthmatics... more here...>>

Cheap Chinese petal dishes, such as those made by Jonsa, are made from thin metal and will distort very easily if not handled/supported adequately when transporting, assembling or during installation.

The picture you posted shows that that particular "pucker" does not extend beyond the fold in the metal and therefore will not be a problem.

If all the of the "puckers" you refer to are on the outer edge of the dish, such as the one I referred to above, they will not cause a problem provided that the dish proper has not suffered in any way.

And no, they are NOT fine-tuning!

Here is a picture of a Jonsa 1.8m panel dish, such as I referred to earlier in this post.

They wont make any difference. I have one or two on my dishes from people trying to move the dish from the panels instead of from the frame.

Here's pictures of the 1.8m solid I get from Jonsa. However the stainless steel frame made here. I do live in a country that last week at my place had 200mm of rain just in 12 hours at my home.

I also replace all the bolts holding the panel on with stainless steel bolts and add washers which Jonsa don't provide.
The bolts they do provide will just rust and eat away into the dish frame otherwise.
Also a 1 piece solid there are only 2 bolts at front of dish where panel mounts to frame and 2 bolts for the elevation pole.
Takes me about 15 mins to put a dish together and get it on a bird.

Same again two 1.8m solids on 124e and 128e ku band sky perfect Japan satellite. Stainless steel frames again.

That's clearly a more robust Jonsa (solid) dish than those (panel) dishes I've come across locally (Australia).

Yes, the bolts as supplied are a problem and quickly rust.

OT but I love the perspective in that pic... looks like a monster dish, or tiny tech with a cable next to it.

I'm assuming it's a large hose he's handling... not coax.

Power extension cable.

I'm thinking perth used to get the Jonsa petal variety in 1.8m. But old mate said they don't get em anymore, wodner why they stopped.

Would be worth getting 1.8m just for now to see what sort of strength signal it gets. Then perhaps using it later as a fixed on Intelsat19 or somethin. ppl here saying 2.3m the way to go if you want exact copy of 3m mesh

[Tappet]

My 2.6M one piece solid has the same performance (roughly) on C band as a decent 3M mesh I had.

The 2.6 is a AceSat dish- I think, that use to be used sit on top of pubs for horse racing years ago in the old analog days. The surface accuracy is still great, probably good as the day it was made but thing weighs a ton, as does the mount.

At the end of the day when it come to C band it's not the lack of holes or no holes in the dish, it's the surface accuracy.

Sill works well but hardly ever use it these days. Wondering what I can use it for now. Was thinking of using it for completely rain fade proof dish for my Foxtel or even converting it to a SETI dish :-)
