TFC (Times Fiber Communications) vs CommScope? CATV vs satellite?
TFC (Times Fiber Communications) vs CommScope? CATV vs satellite? I just paying $ 30 for a roll of 1000 feet of TFC Analog [http://www.timesfiber.com/] RG6 Quad Shield. Black PVC, flame retardants, 60-40 single released on the label: T6Q-VBV Series 6 Quad NEC 820 CATV (UL) 18AWG Published Jul/07 E86650-2 printed on the cable: TFC-T10 File No. E86650-2 CATV (UL) 6 Series 18AWG FT xxxx How CommScope compared to TFC? Which is better? The cable is rated for cable TV [1 GHz], but this cable can be used for satellite television [3 GHz]?
@ 1 GHz, attenuation is 9db/100 feet. @ 3 GHz, attenuation is near 18db/100 feet. (That's not twice – db registration is not linear. 9dB Additional loss is almost 10 times.) Can I use satellite? Yes, if you are wearing a pair of feet. If you need 1,000 feet, the attenuation @ 3GHZ is 178db. What it means is that, technically, there is no signal at their end, but if the power cord with a 1KW transmitter instead of a satellite dish, you probably signal will not see enough to know how bad it is. LMR-1700FR not be bad for the 1,000-foot run @ 3 GHz – Only 19db loss. And at least one new mortgage about your house. (It's $ 20/foot, and accessories are a few hundred dollars each. But it is not necessary to a feed of halogen.) OIA, 1,000 meters to 3 GHz is not you want to do. RG6 And it's not something you want to 3GHz.
