Here on a pretty windy day in Manchester, we are installing an MZR-20 high gain digital television aerial with a 4-way external splitter. The customer had just moved into the property and wanted 2 rooms connecting quickly. They asked for a system that can be expanded on at a later date without adding additional aerials and using this method we are able to run 6 rooms externally.
