[QUOTE="sonnetpete, post: 793575, member: 310216"] Recently I was tinkering about with my TD88 which has a Triax multi sat bar which held eight LNB's. Now that we have stronger signals from 7°W I decided that I no longer needed 26°E on this dish and removed the LNB (reception of Badr was always tricky due to closeness of 28°E). Using the now spare LNB holder I realigned for 28°E as near to dish focus as I could. Surprisingly the results were quite poor (only in the region of 50 - 60% SNR) Now most Triax users have grown to "love" the idiosyncratic LNB support arm. Through experimentation (ok, pushing it up and down) I found that I could gain 10 -15% SNR. However having no spare matchsticks at the moment I searched around for a more suitable and durable object to insert in the space between the arm and the dish. (the weight of the multi sat and LNB's made the problem much worse). Luckily I came across a very handy piece of plastic which was both the right size and thickness. Being loathe to throw out anything, I had some spare fittings (spacers brackets etc.) from my IKEA kitchen units. One of the spacers fits perfectly and has proved a really excellent solution. I now have an extremely healthy 99% SNR on some 28°E transponders. [/QUOTE]
