I have a second home with a Dish 500 Twin dish which uses a Terk splitter to add OTA signals from from a Terk 55 amplified antenna. I use splitters again at the receivers (301 and 501) to split the OTA signal from the Dish signal. This seems to work pretty well. I plan to upgrade this setup by replacing current dish with a Dish 1000.2 and replace the 301 receiver with a VIP612. I will continue to use the 501. Are there any issues with this setup?
