[QUOTE="Vipersan, post: 806411, member: 325666"] Ok ..My TD110 only covers 30 East to 58 west ...but is my best ku performer.. I have the TD88 which covers 5 East to 66 East ...so full coverage of the arc with 2 dishes but of course the TD88 is smaller so reception is limited. There has been much discussion about 36 East ...but the TD110 can't 'see' this location ...and the TD88 isn't big enough for good reception ..approx 8db from 11439 H tp C11 RRsat Global Communications Network ...and of course nothing from the TD110.. Both are fitted with a black ultra at the focus.. Enter Christina which as you probably know ..I use exclusively for C band ..and performs exceptionally well. She's never been particularly good in ku ...but IF I could get anything close to the TD110s capability at 36 East ..I'd be happy. The first problem is that the focus is occupied with C-band ..so it has to be an offset ...thus I've obtained another long neck ku black ultra and mounted this approx 5 degrees off focus ... Optimised as best I can atm ...but performing better than the TD88 .. 11439 H tp C11 RRsat Global Communications Network is coming in at 9.8db ...remember the TD88 only manages 8db (all db referenced to the F15) ..but I cannot of course compare to the TD110 which draws a blank due to the troublesome tree. So ..to compare a common signal I used BBC world news at 0.8 west ku. The TD110 pulls a mighty 16.7 db ... Christina (pf) a respectable but insufficient 11.2 db. So ..In conclusion thus far .. Christina with a black ultra (wrong feed as its designed for an offset dish) is performing better than the TD88 ...but not as well as the TD110 ...but then the lnb is offset by 5 degrees...so what should I have expected ?...certainly not miracles. My last hope is to cut the feed off the black ultra ..and graft an invacom adjustable pf feed onto it .. This is the next experiment.. If I can get above 11.2 db at 0.8West ..ie ..anything close to a black ultra at the focus of the TD110 ...I'll be a happy bunny.. Not expecting 16.7 db ...but would be very happy with 14 > 15 db .. Anyone think fitting the invacom feed will achieve this ? 11.2db to 14 db is quite a big ask ...and remember the lnb wont be at the focus ..but will have a pf feed instead of an offset feed .. Answers should be texted to ******* ...to arrive no later than *****. Late answers will not be counted but may still be charged for.. :D rgds VS [/QUOTE]
