Need to tweek it a little

[slater]

Hi,
Earlier last year i had a 1m motorised dish with a 0.2db lnb profesionaly fitted (as i knew very little about them) paired together with a TM5400ci.
Since then however i have really got into things and moved on to a Dm7020si and now have a rough understanding about things.
Recently we had some very strong winds and thankfully my dish held up well, apart from it was just slightly nudged on the elevation of the dish (i think!). My problem is:
All available sats are ok apart from, 5e viasat channel signal strength has dipped to 80%. The Nordic beam on 1w, and Astra 3A at 23.5 cannot be recieved at all even in perfect conditions, and the S1 beam of turksat is only just watchable without clouds. Before i was having much better success!
My question is: To check wheather or not the elevation is out, are the markings on the side of the motor my latitude position? and if so do i understand corectly that by using one of the online calculators this will tell me what the angle of the dish needs to be?

I should mention the dish is mounted to a polar mount motor, 2'' vertical pole with T & K brackets. My co-ordinates are 53.5 N, -2.6W and my calculations say: Polarmount axis angle = 54.25, & dish elevation = 28.76. would this be correct?

Many thanks
