[QUOTE="nelson_b, post: 809164, member: 296628"] hi - looking at yesterdays close up pictures - the c120 flange does look as if it could be quite firmly attached to the feedhorn -- i was reluctant to use a flame/ extreme heat on mine - for fear of damaging the plastic feed cover , which would be hard to find a replacement for -- removing the grub screw and a regular soaking with wd40 and finaly pouring boiling water over the area - got mine -- yours may be more difficult ---- a little shock treatment with a hammer when hot as -- " aceb " suggested can work wonders :) on your picture of the feed assembly it looks as though someone has been trying to drill out the grub screw -- and has not finished the job -- :confused:-- it will never come apart if the tip of the grub screw is still in there -- i agree with "aceb " the inverto black pro c120 is the one to get -- if you go the c120 route -- i have one on my c.m. 1.8 --- and its a fraction better than the inverto white tech that i had used for the past 5 years -- the fibo 1.2 is a good dish and should certainly equal or maybe slightly outperform a channel master 1.2 mine is not being used to its full potential really --- as its squeezed in between the 1.8 and the fixed alcoa - so has only a quite limited arc - and is connected to a skystar 2 p.c card -- not bad but not the most sensitive tuner ----- you asked ---" Can the old and floppy plastic feedhorn cover cause degradation in signal? " i wouldnt have thought so it looks ok on the pictures -- i have had an inverto black ultra go faulty after a quite short time though -(and have heard of other early failures ) - it still worked but just went weak --- i e lost all its normally good sensitivity regards -- :) p.s. i must say the dish looks good on the - "as new" - channel master mount [/QUOTE]
