Why does my Dishnet lnb work better than others?

[rhino1616]

I have been dropping all the horizontal transponders in my multilnb setup. i had a ROC lnb dropped H transponders, I swicthed 2 different Microroyal lnb same thing, switched to Invacom same thing. I though to myself why dont I try my old legacy dual dishnet lnb, I installed it & every single transponder came in PERFECTLY. Does anyone know why, could it be that the dishnet lnb draws less current. I would still like to use my other lnb's, but has anybody encoutered this problem or know why this happens, could it be that dishnet lnb's draw less curent from the ird?

it also depends on how you have the lnb freq set if it is not set to say 10750/10600 it can drop the transponders

I have it set to the correct frequency 11250 for circular sats

I have it set to "legacy twin lnb1". I have also tried Twin legacy lnb 2 & standard settings with all the same results. Im 99% positive I have all the proper settings set.
