[QUOTE="oneill, post: 24203, member: 176292"] I have a 1.25 m dish (symmetrical with the LNB held in position by three arms converging from the edge of the dish - i.e. it is not an offset focus dish). Sadly I havent got a bracket for the LNB, so I making one out of an old bicycle tyre, an empty Heinz baked-beans tin and ½ lb of blue-tack (well not quite, but ...) Im in doubt about: - Should the dish focus on the surface of the LNB head or the diode-thingy inside it ? - If the latter is the case, how far inside is the diode ... is there anyway of knowing ? - Lastly, but not leastly: what distance should the LNB (diode or otherwise) be from the dish surface, given it is symmetrical and 1.25 cm across ? Kind regards Soren - Denmark ... where I hope to get BBC back, now that CH4+5 seem to be going out ... [/QUOTE]
