HN7000S best signal is 29

i have a hn7000s my dish is pointed at 227 azimuth, polarisation +40 and elevation at 37.

I'm at 44 east 33 north my feed horn is set up with 505 number and the single hash mark on the throat is away from the assymbly like i've read here on site.

In my info i got with the dish my lnb polarization is vertical and tx polarization is horizontal in the manual  commissioning info were u enter al the info for your modem i have it as recieving polarization vertical and transmit polarization horizontal is the receiving and and transmit backwards??

I've tried switching them but it only worsens and i know everything else is correct in my info weve tried sweeping the sky  and everything but best signal is 29 donno if you can help.

so just move the whole thing so that the single mark and the feed numbers are still directly away but it now on the side ?? kk ill try it ty

The single tick mark on the spacer tube must always be directly away from the feed support arm.

There is a joint, with 6 small screws, where the filter/LNB assembly attaches.  There are two alternative positions.

If the filter arm and LNB are at the side, either side, the nominal receive polarisation is vertical.

The image above shows vertical nominal receive polarisation.

If the filter arm and LNB are at the top, away from the feed arm, the nominal receive polarisation is horizontal.

The image above shows horizontal nominal receive polarisation.

The two small white yokes may now be finally tightened, exactly in the middle or exactly sideways.

Polarisation adjustment: If you have the Prodelin dish with the mode match feed there will be a giant circular polarisation scale behind the dish where you set the polarisation adjustment angle. You rotate the entire reflector and feed arm and radio assembly as a whole using this giant scale.

The image above shows the polarisation set to +30 deg.  The whole dish has been turned clockwise, while facing towards the satellite.  During this polarisation rotation, the beam pointing remains fixed, unchanged, towards the satellite, and at right angles to the metal polarisation plate scale where you can put an inclinometer.  You need to set about +43 deg (my guess).

If there is confusion about whether or not you are supposed to be receiving nominal horizonal or nominal vertical, don't worry.  Just set is one way correctly, with the single tick mark exactly away from the feed arm.  Then you can turn the dish +40 deg clockwise; if no good, turn a further 90 deg to +130 deg.  That will enable the opposite polarisation.  It will work perfecty well, even if it looks unusual with the feed arm high up.   Note the beam will stay pointed at the satellite all the time.
