The pre-amp's housing should be mounted on the mast right below the antenna, where it will cancel out the signal loss that's now occurring in the coax cable between the antenna and your in-house amp. The pre-amp's power source goes inside the house (such as behind the TV); it sends a small amount of DC current to the pre-amp over the same coax cable that provides the signals.

Since the 7777 is a powerful pre-amp, it is a replacement for the in-house amp, not a supplement to it. Two amps are usually not better than one for digital reception!

Suzzie, first girl you didn't say you lived 18 miles ESE of me, and pick up some of the same channel. Though you are far enough away to pick up some I don't. But our antenna solution is very very similar.

Good thing you are at 30 ft, because that is needed in our area. Hope your VHF/UHF antenna is a big one.

Just for my interest I would love to know the model number of your amp and what channels you get after suggestions. Help me a lot in the Gainesville and Orlando threads over at the AVS forum where I post.

Don M nails it without your plot. Channel Master 7777 is your preamp, period. (actually you nailed it also, but with the data we have now, it's a no brainer). Channel Master CM 7777 Titan2 VHF/UHF Antenna Preamplifier with Power Supply (CM7777) | CM7777 [Channel Master]

And as Don says, remove your indoor amp, sell it on craigslist, throw it away, just don't use it. It will ruin the beauty of the signals out of CM7777.

The CM7777 has to be mounted up at the antenna. Also another good hint if you are installing it yourself is to not use quad shield between the antenna and the amp, with a rotor, it's too stiff. Be sure to leave enough cable so it can rotate and hand a little below the amp so the rain water drips off and not in the amp.

That should make things much better. But remember Suzzie you are DEEP FRINGE and some stations there one night won't be there the next.

If you buy the CM7777 please hang around to tell us the results.
