I have been reading many things on this site and learning alot and sometimes getting confused a little. What LNBFs from Directv systems or DISH systems are suitable for legal FTA??? I thought that all of the LNBFs on the little dishes were for circular signals only!?!?!? After reading some threads it sounds like some are or can be set up for linear. Which ones are the good ones??? I am pretty sure the LNBFs off of the old 18" dishes were not good for much. I have some leads on some newer style dishes and want to latch on to them if I know that they work for FTA. My pile of the older style dishes is getting big and I know that they are limited to certain legal uses only and I think I have enough of those!
