Any Tips and Tricks For Separation Between Inside & Outside Antennas?

Remember that antenna separation can be horizontal, vertical, or a combination of both. If you don't have much room in your establishment for more horizontal separation, a vertical separation is a lot more effective than horizontal separation. This is simply because there're more obstacles between the two antennas like multiple ceilings, etc. in for example a two storey home, and simply because installing an outside antenna higher may mean that you can get away with less antenna separation than actually required.
