Orbitron SX-10 Dish

I never had any issue with the buttonhook as it's very solid, sliding into a tube welded to the faceplate of the center compression hub. Somehow looked better to me than the 4 struts as well. Also with the low f:d ratio it's fairly short.

Who knows, maybe one day they will make solar panels light enough to use for dishes again. They do have them, but everything is so heavy, and they cost too much.

I love it when a solar salesman asks me to buy it. I say Sure, if you come back every six months and clean the panels of dirt and bird poop.

Hands down, prefer a well constructed buttonhook design over a 3 or 4 leg support. Optimizing the FD and FL is a breeze with a buttonhook... Not so much with 3 or 4 leg supports and shims. Always carried several cans of penetrating oil and added many buttonhook guy wires to customers BUDs over the years.

Right, for the ones that weren't so solidly designed and thus flexed. I seem to recall claim made that buttonhook blocks more signal than struts, because it's blocking some of the reflected (magnified) signal rather than some of the ambient signal (before reaches the dish). But yes, far more amenable to focal length adjustment.

I now also recall a buttonhook with a plastic adapter shaped like a funnel that the feedhorn sat into (so that you couldn't see any of the front of the feed). This was, I'd guess, to address the inevitable small amount of signal blockage inherent in any metal support. The signal would presumably pass through the plastic unimpeded.

Possibly fractionally? I think that claim was made by the brands that only offered leg support designs.... LOL!
