If you have bought the 135 degree inox brackets with the new arms you should be OKThanks CH I have got a replacement corotor coming but I will have a play with the old one as it does have a fair amount of corrosion one thing I did notice was the feed is pointing about 1 foot above the centre of the dish so it must have moved over the years . While I am changing over the arms I will realign the feed point with the centre of the dish . Light you say might just require a bit of WD40 but the centre does move by hand yes I have had the motor off before , I might remove the motor then give it a skew control and see if it moves or not .
The new arms were made up by Rimants and clamp round the neck of the corotor and not the scalar ring but I have worked out the plan to get to the old top support rod just move the dish over to about 70 east then get the step ladder in I can reach the top of the rim and the support rod . I will try a good spray of WD40 and leave it over night if all fails I will attack the nut with the dremel .
Dremel, WD40l!! Common , Brian, just take angle-grinder with curt-off disc and split all rusted nuts@bolts.I will try a good spray of WD40 and leave it over night if all fails I will attack the nut with the dremel .
That is what I am saying, you will not use those rusty parts anymore, so why should you be gentle to them?! Angle-grinding will not do any harm to the dish if you use it in the right way. Anyway, good luck.I will start removing the old arms who knows they might just unscrew .
Thanks John for the info on the Norsat C Band LNB Yes seen a few of those on Ebay my old Gardiner is still working but I might just well go the full hog and replace the C band LNB as you can see with the corotor the corrosion is very bad . One thing I will do this time round is remove both of the elbows on the corotor and bolt both LNBs straight onto the corotor as we all know bends on waveguide means loss I did this before with the C Band but this time I will to it to the Ku side as well I seem to remember the Ku elbow is held by 4 x Torx screws so it should be straight forward to remove .
As for the hunt for a SMW Ku-Band Quad there are a few S/H type R that I have found but the seller wants almost the same price as new , Does any one know what is the spec of this LNB is its model NII 1000XA Ku-Band LNB Ive been told its Quad but can find nothing to confirm this .
As for Arc well 30 years ago I could go as low as just past 60 east and west was about 60 west then my neighbour put a 6 foot fence up .My problem was that 10 months of the year I was away so did not find this out until I return , So I bought the guy a 5 foot fence panel and I put the polarmount on a 2 foot concrete block so the 1 foot of the dish rim has the fence panel in the way but I can still see stuff even with the fence covering the bottom in those days I used this scope Luly but these days I use the sat look . I also need to give my jack a good rub down and a respray so got lots to do while we still have the lock
I wonder what you receive John with your Extended C-band lnb I wont be able to use that with the corotor as it only covers the standard C .7 -4.2 maybe I could mount a offset lnb and feed to the new mount .
Thanks again to all the info as got a lot to learn all over again .
