Can't help adding comments.  In the early 1970s, I worked for a company 
installing in-room movie systems in hotels.  I was assigned to survey 
the master-antenna systems in the hotels to see how usable they were.

In one hotel, I took the cover off a box I thought would have contained 
a splitter to find five coaxes all twisted together.  The center 
conductors were all twisted together as were the braids, and then the 
braids and center conductors were twisted together.  The channel amps 
were pumping 84 dBmv into that.

Better still was a motel where I went into a room and turned on a TV to 
see how the pictures looked.  They were noisy and had some ghosts, but 
I'd seem worse.  So I unscrewed the wall plate to see what kind of 
splitter or tap they were using.  When I took off the plate, I found 
blank wall behind it.  I tried several other rooms and found the same.  
I then had to explain to the motel manager that we couldn't put movies 
on his master-antenna system because he didn't have a master antenna system.
