[QUOTE="jeallen01, post: 992404, member: 176704"] )You don't plug the holder into the dish LNB arm - you leave the existing LNB in place and fit the clamp for your central LNB around its body (which means that you need a central LNB with a fairly long 40mm diameter section on the body, and not all LNBs have that - Technomate ones are good in that respect). That leaves you two spare LNB clamps: one should be on each side of the central LNB already on the dish. The central LNB should be aimed at 19E and you need to adjust that for best reception before you do anything else; and then the one on the left (viewed when standing [I]behind[/I] the central LNB ) will be for 28E, and the one on the right will be for 13E - and then you adjust those separately for best reception. PS: be careful when opening those LNB clamps to fit the LNBs because they can break at the base (I've had 2 do that) - so do it gently! PPS: you then adjust the angle of the support bar up (on the left side then that "up" for 28E) to get the best reception. PPPS: in some cases you [I]can[/I] add a 4th LNB to the support bar, but it's difficult and you need very narrow-bodied LNBs or else they physically interfere with each other. OTOH, you could bolt a metal strip on one end of the existing support bar, but it will need bracing back to the dish or it will "wave all over the place" if touched or if there is any wind (been there, done that!) PPPPS: Your grasp of the English language is actually very good! [/QUOTE]
