Best solution for automatic aiming for DISH reception

for our seasonal location, we bought a dish western arc antenna and tripod off ebay for less than $200 and it works great.

Our roof mounted KVH dome, while it is programmed to recieve 110-119-129 dish satelites, is always a pain, and our seasonal site is heavily wooded, it only gets 119 there.

It would seem odd your dome won't get the dish satelites, there should be a way to reprogram that unless it is very old.
