    At times like this I wish I had my motor on my dish. I've 6 lnbs on my 1.1m dish arm, Christ does it wobble in the wind. Might try to put some extra linking brackets on the lnbs to stablize it, but I think its the arm its self wobbling in this wind.

    Mine's ok, six lnbs on it, but it's low down and relatively sheltered. Motorised dishes have a nasty habit of twisting on the motor stub, so they can be just as problematic.

    I replaced the supplied U-Bolts with ones that I made myself with 10mm threaded bar. I find it gives much better grip and not as prone to twisting on the motor arm.

    Mine has been rock solid with 7LNBs on it.
    Located on a south west facing wall @ 15ft up.
    I had a little bit of attenuation last week during the peak wind/storm but nothing needed readjusting so I'm happy out with mine.

    I noticed this as well on a TD88. The LNB arm is fairly light aluminum and really cant handle the weight of 6 LNBs. That bolt that is meant to used at the arm base is worse than useless.

    There are a lot of cheap way too light aluminum mounting brackets out there too.
