Understanding you need for a good reliable connection for business or educational purposes. In most cases, the best solution is a direct connection from the dish to the Wally receiver. drilling a hole through a wall or floor is not a big thing, all it takes is a 3/8 inch drill. It you do go through a wall that is visible from the outside, there are several types of external wall plates available that can be weather seal with just a bit of goop or calking. If you can drill through into a basement storage area, that is even better. If you can access into a storage area, then you can attach a new coax to the receiver, then directly to the satellite dish with only one continous length of coax, and no additional connectors in between. When not needed, just roll and store the cable in the storage area. This would allow the best possible connections and signal.
