...One other item that could have been proven with the 1996 catalogue would be the different feed arms supplied by Precision for C and Ku band variants, since the holes in the reflector remain the same, there must be a difference in the lengths to allow adapters for the same focal length...

This point is correct, the lengths of the feed arms were different for C-Band and Ku-Band feeds for the same size reflector. I have both the C-Band feed support arms and the Ku-Band feed support arms for a Precision 1.5m dish and confirm they are different lengths.

...I wish I had the right support arms for the dish but all I have is threaded bar ...

In the absence of the original feed support arms I can highly recommend the adjustable stainless steel feed support arms manufactured by forum member "RimaNTSS". They are high quality and do a great job. In addition to stainless steel feed support arms "Rima" has also manufactured stainless steel feed holders that can accept either a C-Band LNB or a Ku-Band LNB for a prime focus dish with three feed support arms.

I have attached a couple of pics below of an adjustable stainless steel feed support arm, the pics do not do it justice, they are an excellent quality product.

Thanks manys MoonBase for the reply yes I had a feeling you did not paint the whole dish as I hate to think how many cans you would use . Ok on the Cromadex 2K paint in RAL 9010 white. I found this paint online . I hate to think how many cans I am going to need for a 3.7m dish , I will only do the bad bits on front as the rear is fine . As far as the primer goes I used Hammerite Red Special special Primer this was on my rototor that had been up on the tower for over 40 years but nothing like the size of a dish one thing is for sure I need to wait till it gets warmer before I start doing spraying some thing this large outside . But I will take the muck up off the dish with the karcher .

Any way I get this battery replaced and get the sat look up and running again but heard nothing back so far regarding a ADC1 from Germany so it looks like the states but looking at the companys there it was Discontinued - October , 2019 So looks like looking for old stock .

I wonder who on here watches C band on here and what spec Lnbs are you using ? Mine is a 30 year old Gardiner 40 Kelvin .

Oh yes your support arms are much better than mine as mine are just steel threaded bar and now its more rust than steel were did you buy your adjustable stainless steel feed support arms from ?

There is a C-Band section on this forum but it is not as active as it was in the early days of the forum. A few of us try to regularly contribute to it but new faces are most welcome once you get up and running again. For LNB's, I have tried Norsat single probe PLL, Titanium twin probe PLL, Chinese single probe and Chinese single probe for the extended C-Band range of 4500-4800 MHz.

I have pasted a link to the C-Band section of the forum below.



As indicated in my earlier post, I had the adjustable feed support arms made for me by forum member "RimaNTSS". He is based in Latvia but shipping cost to the UK is reasonable. In my personal opinion, the feed support arms and postage cost are great value for a high quality product.

...Your 3.7m dish has the same focal length as the Precision 2.8m and 3.0m dishes at 1207mm. The difference between them apart from size was the location of the 3 x press stamped feed support holes on the dish surface, they get closer to the edge as size increases. All three dish sizes shared the same length of feed support arms.

Correction:

I made an error in my post (reply 65) where I said the 3 x press stamped feed support arm locating holes get closer to the dish edge as dish size increases for different size reflectors that share the same focal length and feed support arm length.

It is the reverse, the feed support arm press stamped holes are nearest to the edge of the smaller dish and furthest away from the edge for the larger dish. I checked the pictures of different size Precision dishes I had worked on that shared the same focal length and feed support arm length to confirm this point.

I have attached some pictures below for Precision 1.8m, 2.0m and 2.2m dishes. These three sizes all share the same focal length and feed support arm length. The location of the 3 x press stamped holes can be seen to be closest to the edge for the smallest dish and furthest from the edge for the largest dish.

Thanks MB on the info on the links for C band + feed arms yes I think that will be a good idea to change mine out over the summer the only problem I have is going to be getting the old steel ones off due to the rust and corrosion I will give they a good spray of WD40 if they still wont come I may have to cut the nuts off with the dermol . Once I have the new arms I think I will change one out at a time since I remove the whole thing its going to be a bugger to reinstall all 3 arms at the same time by myself .

John I did contact Titanium Satellite Sales last night and they confirmed they stopped making the ASC1 but they told me to contact SkyXpress :: Positioner on checking on there web site they have some in stock so I hope they have .

Thanks again guys for all your help .

Alpi, our man in Rhodes with the 1374 was using an ASC positioner, it was having trouble with the standard actuator mounting points at the extreme low elevation satellites. He might know where there is somebody with stock or potentially sell his one on.

That is most gracious of you. I am happy to update my errors with a correction, it is not an issue for me.

I notice in your "counter post" yesterday you made no reference to your joke about coronavirus, are you considering an apology for that joke or do you think it unwarranted?

Thanks Channel Hopper I will drop Alpi a PM and see if its still available , As there be no import duty from europe but 25% from USA , I wonder what satellites he was having problems with a very low elevation satellites here its about 70 East to about 60 west buts all down to the time of year with the trees .

If you have no luck in sourcing a Titanium ASC1 unit I have a spare Research Concepts RC2000 dual axis controller with skew control that I could loan to you for a few months for testing purposes.

Thanks for the offer MB I will first see how I get on with sourcing one or I might get lucky finding a suitable receiver but we have 10 weeks of lock down to go so lots of time since I retired I just take my time the same way I did with my tilt over tower , To service that andl replacing all lift cables and feeds it took me about 10 months that did include stripping the rototor down since it seized up .

But I have sent RimaNTSS a PM for the feed arms but stainless steel would be much better than these steel ones .While out in the garden I take some more pictures so I can show RimaNTSS what the require is but it should be a case of using my current band that goes round the scalar ring and just replacing the arms one at a time or just remove the corotor to remove the weight plus if these bolts that screw into the end of the feed arms might need heat to remove the bolts . Then use the Sat Look to set the feed up for max signal .

Were abouts are you in the UK MB I am in the north of Essex next door to the A12 .

I am in Surrey, just a few miles from either junction 6 or 7 of the M25 and about 30 miles from the Dartford crossing.

Oh your near then in Surrey down A12 M25 over the river and carry on the M25 . Ok here are some pictures of the band going round the ring then bolting to the steel arms so just means remove them one by one and replacing them with SS ones . but I bet there all seized up .

Is there a reason why you wish to replace the feed support arms one by one rather that remove the entire feed assembly? I can understand that you have the scalar in its clamping ring at the correct focal distance from the dish but if you measured the appropriate lengths of the existing assembly arms from the dish face you should be able to replicate that when reassembling.

If you were to remove the entire feed assembly it would only need the three nuts at the rear side of the dish removing in order to lift off the feed setup? By adjusting the elevation to place the dish in something close to a "bird bath" position it might give relatively easy access to remove the three nuts and allow lifting away the feed setup from the dish.

You could measure the currrent elevation of the dish using a digital inclinometer on one of the vertical struts of the square frame section that the dish is secured to and use that angle as a reference to return to after a "bird bath" tilting of the dish.

Hi MB The main problem here is man power because there is only me here so if I could do one arm at a time I can do it on my own if I remove the whole thing its going to be a nightmare try on my own to refit the arms . When I was fitting my HF beam to my head unit on the tower it took 3 of us to re install the boom thats 32 feet long and 3 inch dia and I had to hire 2 guys the dish is much smaller but you need to think one step ahead when your doing it on your own . Any way still waiting for my Torx screwdriver set to remove the battery clamp on the sat look so cant do much until I have fitted a replacement battery . But when the Sat Look is up and running again I might remove the corotor from the scalar ring then see what I can do with the arms assuming our friend can make up some replacements .

It was clear your feedarm post was littered with a number of fundamental inaccuracies, hence the response, 'Eh ?'

It should have provided the impetus to check through and correct as necessary, for that I apologise for not being clearer with my retort.

My feedarm post was not littered with innacuracies, it contained one error about the positioning of the feed arm support holes with repect to dish size, hardly litter.

Please do not quote my replies out of context, it is my personal opinion that you quoted me out of context with your "Apology Accepted" quote. I was correcting an error I made about the feed support arm holes for the sake of accuracy and future reference should it ever be needed by any forum members.

In order to return this topic to one of satellite related content I will restrict my future replies in the topic to relevant points about the equipment under discussion.

Hi Trust yes it does run of the power adapter but far better to wait for the new battery to arrive since less cable to pull around . It should arrive next week mine you I still waiting for the Torx screwdriver setweek mine you I still waiting for the Torx screwdriver set to remove the battery clamp .
