That's a de-icing system. Starlink dishes have the opposite problem, they get too hot because they have to dissipate 100 watts electric energy plus the heat from the sun and the nearby rooftop. OK, maritime outfitters will sell you a climatized radome, which will set you back a few grand. Proper engineering costs money (can't have radar fail in the middle of the Strait of Malacca), and that's why Elon relies on his army of fanboys, Elon's outrageous conduct is part of marketing.

To be fair, isn't the maritime market a bit like the aviation market, where a pack of 6 disposable AA batteries potted in a pack will cost you $43?

I'm not sure how much water you would actually need though, it might be an unconscionable waste in the regions that are prone to these sort of temperatures in the first place.

Fair point, a portable AC sets you back 150 dollars or so, so with outdoor proofing and all, you can build a passable cooling system for 250 dollars. That would be the proper engineering solution, but it wouldn't look cool, like the steering yoke in the recent Tesla.

What sort of magical solution is there though for the price of the dish? If the ambient temperature is 50 degrees C, you need cooling. It looks like the Hughes dish is a little better at 55 degrees C. Looks like the expensive solution is that randome irrespective of the particular dish. The cheap solutions seem to be myriad. Relocating it, putting it under shade, sprinklers, fans.
