I will try that test when I get a chance, thanks for the suggestions.
To answer your other questions, the aerial is in the loft and the amp has the traditional (as I know them!) co-ax sockets, not F-connectors.
Mike: I am splitting to 6 room sockets which all have an outlet, I'd like them all to be usable without poking around under the stairs, although currently only one is in use. Hence an 8-way amp (obviously 6-way would do!).
An 8-way SLX amp is inexpensive on Amazon so I may as well.

David Nash: Yes, I would be interested to know the outcome of the "short wire" instead of aerial test, as obviously the signal level being fed into the Wolsey amp from the wire aerial would be a great deal less than from the aerial and I was curious as to whether the amp would still lock up or not, because if it didn't, then an attenuator could be placed in line between the aerial and the amplifiers input.


The undermentioned links are for an SLX 6 way distribution amplifier with built in 4G protection, the second link being for the same amp but with a more detailed specification being given. (by clicking on "specification")
