[QUOTE="nelson_b, post: 1040942, member: 296628"] HI - Made up some "temporary" arms for the 2.4 c.m. to see how it performed in k/u without its subreflector and dedicated feed ... played around for a while using a normal channel master feed and C120 l.n.b. results at Amos 4 west were decent - but about 1.0 db down from subreflector results on 11176 H 30000 swapped the l.n.b. for a standard Black ultra single and gained back most of the loss 8.0 to 8.1 db with sub .... 7.9 to 8.0 with black ultra ..... spurred on by this i ran a 2 MHz blind scan with the F15 at Amos 4 West and turned up 1 middle east beam transponder. The idea to run the dish without a subreflector is that i might then be able to fit 2 C band l.n.b,s either side of the k/u as this arrangement has served me well on the 1.8 .. which would be replaced by the 2.4 setup if the results are good enough ....
