This four story condo building has 4 units on each floor. Only 3 units were using DirecTV until we began the upgrade. There are 2 dishes on the roof that we can't get to without much expense (renting a lift). One dish has a very poor signal and had been disconnected over a year ago. The other dish is providing an adequate signal but not what we would like. The old switches were a combination of cascaded 6x8 & 6x16 to provide four cables/signals to each condo. Our plan was to keep 2 of the current users on a 6x16 and add a SWM32 to provide new service to one current user and 3 new users. Unfortunately, we were not able to get an adequate signal from the dish to split between the two systems so everyone is going on the SWM32. We will need to add another SWM32 for additional users. What recommendations can you give me regarding connecting the next SWM32. Will using the cascade ports be the best solution or should we use a MST 774/771 to split the dish signal? Do we need an amp? Another issue has been older receivers (H21s) in an existing installation that doesn't see the satellite. We tried forcing a software update but there wasn't a good enough signal to get the update. These same receivers were working fine on the legacy switches. Any ideas? Thanks.
