    I needed to be able to tighten the bolts without them having a load. For me, manhandling to tweak in micro adjustments and tightening the dish would always end in average results. With this, it doesn't bear any particular weight once the dish's elevation nuts are tightened (I made sure to use washers) so it should last as good as anything else in 8 months of rain per year. Looking at it now it couldn't have been easier and I am seeing signal levels that I've never had. I peaked the elevation with the turn buckle, then tightened the elevation bolts - the signal levels were unchanged. Once the nuts were tight, the adjuster doesn't have any real load on it but would be able to take a load if needed (wind?).

    Mad, it looks like the arm for your lnb is upside down. If it were flipped over then you could move the lnb back to the end of the arm and not have to use the block. I have a 90cm dish but the arm has that same bend as your dish and the directions showed it opposite as the way you have yours attached to the dish.
    Anyway, just a suggestion.

    tried that. thanks for the thought. even drilled holes to bring the support rods higher. shes parked at 125 and happy it does something.
    and i did not take the sledge hammer to it like i wanted too a few timeS. was told they sent me the wrong lnb holder twice none of the 3 worked right from the back hole(flipped). # 2 is on it.

    The LNBF is not aimed into the correct area of the dish. The face of the LNBF shouls be aimed at the bottom third of the reflector. You are lucky if you are collecting half of the reflected signals.

    Fortec 120cm 1.2m dish assembly instructions

    Yes, good eye Brian - Mad's lnb support rods are Left / Right reversed and upsidedown. I've attached the assembly instructions for the fortec 1.2m dish.

    As Brian pointed out, the lnb is at the wrong spot for the focal point. If you have the lnb holder that came with the dish - it looks exactly like the one in the assembly instructions attached - it does work better than others I have tried on the dish.

    thanks guys
    hoping you guys are right but may never touch that dish again unless become bored near death.
    still don't have that lnb holder. but did try all that were sent and moved that arm both ways for each.
    did not get any assembly instructions. would have helped at least would know Still have the wrong lnb holder. yet not sure it's a fortec no stamp on it all my others have one.
    kinda wrote it off as 1 bad saduon buy(unmarked Chinese junk) and everything else i got there was very good so...
    when ordered it was a white dish with the stamp well when opened it was that and things near never got better.
    will look around for That lnb holder. got other projects now. that sucker has been so frustrating my stomach churns now.
    my first big cband dish took less time out of the box.
    that said it gets all the pbs stuff really good for over a year now. yippee
