    More than adequate for a good strong signal in all weather.

    I`m not so sure about the percentage either. Only time will tell. I`ll be putting the dish up either this weekend or next. Will post my results.

    Cheers.

    I found a difference with Select TV on an 85cm as opposed to a 65cm but if there was extremely bad weather then either didn't work!!

    Default Best size dish for Brunei?

    What do you think would be these best size dish to receive optus C1 in Brunei Darussalam? Would a 3m dish be sufficient? Or over the top?

    Details from satsig.net for location of Brunei.

    Latitude = 4.6257, Longitude = 114.3979
    Lat = 4 degrees, 37.5 minutes North
    Long = 114 degrees, 23.9 minutes East

    If you want to point a satellite TV dish at Satellite= 156 East orbit longitude
    Dish elevation= 41.7, Azimuth= 95.4 (magnetic compass), Polarisation= -83.1

    No issues with a 65 cm in Melbourne, even in bad weather - provided the dish is aligned properly.

    A 65cm strong dish is great and served me well for years.

    The Elcheapo thin bendy dishes that installers use with crap lnbs on cheap setups are the problem.

    Use a quality lnb for good signal.

    Interesting trade off. On IS8 a 65cm antenna will give better than 99.95% avail in Melbourne. I've not done the calcs, but a 95cm will probably improve this by half to, say, 99.98%. However, this big increment in availability only translates to a couple of hours per year of additional uptime.

    I spent a lot of time doing link budget calcs accross the country - I gave up doing detailed calcs in VIC as a 60cm antenna always gave > 99.95% downlink availability.
