I notice that there is another, recent post dealing with this subject, but rather than hijack that thread, I thought it would be better to make a separate post for my particular set-up. I will, of course, take note of the information offered there.
I currently have a Lenson Heath 80cm aligned on 13e, with an offset to 19e; the dish is in great condition (aluminium?), but the LNB arm is corroding, particularly at the LNB end. I would like to add 28e, so thought about adding a third LNB, rather than putting up another dish - is this reasonable/practical in the North of Scotland? If so, is it possible to get a replacement LNB arm for my dish, or would I have to get a new dish/arm? If the latter, what are the current recommendations for good quality dishes? Similarly, LNBs? I’m guessing that compact/lightweight (as well as good performing) LNBs would be an advantage? I have been thinking about a quad for 28e, with either single or twin for 13e & 19e.
As I have never tried setting up a dish, how easy is it likely to be for me to re-align the dish, or (more taxing, I assume) install a replacement? I assume that to receive the three locations I am interested in, the dish should be aligned on 19e, so that there are offsets either side, rather than two on one side, which is what would be required with the dish currently on 13e?
Triax dishes have been recommended in the other thread – these are steel, yes? What about modern aluminium dishes? Or plastic? All the old $ky analogue dishes I‘ve seen in the area were rusting to bits a LONG time ago, but, as mentioned above, mine is fine, expect for the LNB arm – not sure if that means corrosion is particular problem in this part of the world, or was it that the majority of dishes installed were of crap quality?!
