need a little help, I'm aligning a single feed (dual LNB) antenna for dish network 119 the super buddy meter I'm using only locks on transponder 2 & 7 is that normal. I'm also having trouble with dish receiver(s) 311 wont stop flipping thru transponders ( signal meter on receiver shows no signal) but I have signal on meter. I have 15 311 receivers 5 are doing this 10 are ok. these have been working for 15+ years. This all started happening after the antenna moved and a bad LNB. any ideas
