-/+ 1-2dB is perfectly fine. I'm sure most coordinators use 11.2GHz and the mid-band gain of the antenna for both Tx and Rx. And you also have stuff like time of day and temperature playing a part.

If you have an idea where to point the antennas and your mounts are level, fire them up and they'll probably be pretty close. I've done that a number of times. We left one side off by 4dB after powering up for a couple weeks because we were going back up the tower anyway so we finished alignment then. Took about one turn on the elevation and it was 2dB better than the coordination.

yeah, we are the PCN is -43 and we are -42/-41 Everything tests fine, speedtests are great, full capacity. I wouldnt be concerned if it had been hard to get the link up.

we did full H/V sweeps on both sides, then fine aligned as normal. I just expected it to be hard to find the link and somewhat easy to use it. on the sweeps we didnt see notable side lobe peaks. just strange.

Im really freaking happy with SAF on this though, great support from moonblink both pre and post sales, input from SAF sales and support directly, quick responses. I guess my only complaint is the product wasnt harder to use

    If you got the signal the PCN states you're good to go.  You can
    also do a speed test to verify your 300 some megs if you need to?

        yes.
        you do understand my concern is that they linked up too
        easily? Im almost thinking we could have just laid the
        antennas on their sides and they still would have made a
        marginal link. If I werent so pessimistic I would be excited
        about this. Im concerned when the ground thaws or something
        everything will go batty
        We have cut the traffic over to it.

                            off the site, only needed to be re-aimed
about 2 degrees to go where we wanted. And they built a platform to stand on

                            HPBW for a 12 ft dish at 11.2 GHz is 0.5
                            degree.

                            Nope, a 4 ft dish in 11 GHz should be
                            pretty narrow, a few degrees and you
                            should be into a deep, deep null. Take a
                            look at the beamwidth or pattern for your
                            antenna. It should be similar to an 8 ft
                            dish in 5.x GHz.

                            We once used an existing 12 ft dish for an
                            11 GHz link and I kept having to tell the
                            tower guy he was not going to be able to
                            eyeball it. The beamwidth was something
                            like 1 degree if I remember right.  He
                            ketp getting nada for signal until I made
                            him slowly sweep the azimuth.

                            on short paths

                            Weve never gone above 2'

                            we finished installing our 11ghz link
                            yesterday and had the antennas rough
                            aligned, one side is 3' one side is 4'. I
                            expected the tighter patterns would make
                            it harder to find the initial link but
                            they actually linked up right off the bat
                            and it was right on the projected power
                            levels.

                            This is only 10 miles, so we have visual
                            on the path.

                            We did a  little rough alignment
                            yesterday, and will do the fine alignment
                            today. when we we roughing it there was a
                            good amount of travel on the antenna (4')
                            side we were on and only a couple db
                            change. do larger antennas on such a short
                            path give you a little more leniency in
                            alignment or something? we will do full
                            horizontal and vertical panning today to
                            make sure we arent in side lobes, just
                            curious is there is more slop in this
                            scenario.
