"swept" means that it was tested at that frequency, it does not necessarily means that higher frequencies won't pass.


Here’s to the crazy ones.
The misfits. The rebels.
The the troublemakers.
The round pegs in the square holes.

The ones who see things different.
They’re not fond of rules, and they have no respect for the status quo.

3.0 Ghz sweep tested isn't much more expensive....why take a chance?

I would never use existing cable for a new install without testing it.

SWM lives in the 1076Mhz to 1790Mhz space. (Guide data on 974 Mhz.) I would think you are taking an unnecessary risk by not upgrading. But, it is your call.

Which was my source for the freqs I gave. But, I like your idea of including the source better.

I would bet for a price of new cable, that old cable would be fine up to 2.2 Ghz (if not 3 GHz) with acceptable linear loss

don't scare him ;)
