Off air Antenna + amp on same wire

[mickel1138]

The subject almost says it all.

I'd like to add an old fashioned off-air antenna, I know this works I have diplexers allready in place from back when I still have cable TV. (Have U-verse now.)

But can I add an inline amplifier for the antenna on the same line, or will it interfere with the switching voltages for the LNB or my motor? I believe the answers is yes, but maybe someone has a better answer on how I might accomplish this. If not i'd just go with the antenna itself. Right now I can receive about 50% of the digital channels in my area, and that's on the disconnected coax outside.

Thanks,

Mickel

personally I would put the inline amp before the diplex so it's only amplifying the terrestrial input.

I use my spaun 5801 this way, it has a built in amp, one for each sat input and one for terrestrial, works really well.

a separate RG6 always works better. Careful if you have a PC card. A diplexer works fine with an stb box minus a few ground-fault situations. But it smoked the lnb power on one of the tuners of my lnb card. I now have to use lnb power from the STB box to utilize that particular tuner on the pc card (via loop out of the stb box). RG6 is cheap per foot if you buy it in the 1000 foot roles.

Yes, separate is best. Dual coax is good for this application. Perfect Vision makes some nice dual coax with solid copper center conductors. That's what I'm using from the satellite/OTA antenna farm to run both satellite and OTA signals separately.
