Hi there... making plans to get a slimline. However, I've read that there was or is a "lot" or brand of slimline lnb assembly that gave very low signal readings and had to be replaced for good ones. As far as I have been able to research there are several manufacturers such as wnc, eagle aspen, calamp, etc. So.. which are the good ones and which are the ones to stay away from? Thanks in advance !
