[R-390] Antenna Coupler

[Mike McCauley]

As I understand, the "traditional" cable systems are now up in the low 
GHz range, and ADSL is fiber up to the last mile, and then VLF over 
single or dual twisted pair. That's what I've heard, anyway.

In Dallas, I know that Time Warner uses a "traditional" RF system, and 
it's up in the 1-3GHz range. Everything but the house drops is 1"+ hard 
line. AT&T U-Verse is fiber except for the last mile. Unknown if that is 
uniform across the CONUS.

I see the old line amps and splitters now and then at the hamfests. The 
chassis would be nice to use as a foundation for a multicoupler, but I 
don't know about "as is".
