I don't have a pic at the moment. Anyways, yes, I did reinforce it. Yes, it's not hard to reinforce. Basically there's a blank spot between the area just in front of the bottom of the lnb and the bottom of the arm. I wadded up some electrical tape around a thin piece of wood that I had that had busted off of a part of one of those things you put behind flowers and stuff and more or less just made a filler for that hole to keep the arm more steady.
I then reinforced that with some electrical tape wrapped around the lnb and arm a few times. The heaviness is not as big of an issue as some make it out to be, but it's significant enough that you need to think about it and come up with a solution like I did. It's really pretty easy to reinforce. Just make sure that your lnb is properly skewed before doing reinforcements. On a motor, that's pretty easy since it's just straight up and down. Without a motor, that may be a bit tricker.
