Tweaking reception

Another question then arises. If the amplifier is located 6' from the antenna then you are definitely using it outside. Is the distribution amp outdoor rated and can you safely run power to it without the risk of electrocution? Probably not. If this is a plug in distribution amp then we are talking about 120 volts of AC power sitting on the antenna mast. It would be safer to install a mast mounted preamp such as this http://www.solidsignal.com/pview.asp?mc=03&p=CM-7777&d=Channel-Master-Titan2-TV-Antenna-Preamp-w-Power-Supply(CM7777)&c=Pre-Amplifiers&sku=02057207774. It's injector is usually plugged in safely inside your home but since the antenna feed needs to move on to the satellite dish that's not likely possible. You could place the power injector just before the splitter if there is a weather protected GFCI outlet available nearby.

Yes, it is an indoor amp, but my antenna is now mounted to a shed where I park my tractor. I can mount it under the roof, and the building has electrical outlets. I may have to use a little longer cable from the antenna to the amp though (maybe 10 ft or so). I'll probably need a ground block too. I have another pre-amp/amplifier combo, but the pre-amp draws power from the amp, and running both before the cable goes into the diplexer would probably cause an overload. If it doesn't work, I'll buy a single pole mounted pre-amp.

If you have ac power and can shelter things properly with the shed, then you should be good. Just make sure that outlet is GFCI protected. Also, be sure to use drip loops and seal all your connections from weather. I use this stuff: http://www.lowes.com/pd_78453-98-2155_0__?productId=3129711 It's self-fusing, stretchable rubber splicing tape (never had any problems with water-infiltration using it).:)
 
So if I replace the coupler with the distribution amp, I should get something like this:

I can't shorten the 150 foot runs because my satellite dish is a good distance from my house in order to see over the hills. I can probably shorten the 25 foot run by a few feet and get another .5 dB.

You could also upgrade the cable to a lower loss one like RG-11/U or even a higher end one.
 
You only need enough amp compensation db's to compensate for the approximate loss you calculate you have. In other words, if you think you have say 12 db loss due to connectors/splitters/diplexers, don't put in an amp that provides much more than that.

We are no longer in an analog world with tv signals, and with the new digital transmissions TOO MUCH signal is as bad or worse than too little. It can overwhelm the tuner, and cause issues.
 
I think I finally got it. I hooked up the distribution amp as above, and fine tuned the orientation a bit. Now my signal is running a constant 85 on the Dish tuner, and 90-93 on the Coolsat meter. We've got some bad weather rolling in the next few days. If the signal holds I'll be really happy.

Good luck! :)

glad to hear it. If you scan in the channel they have ThisTV as a subchanel and they also carry some college football games (like the ACC game of the week and local KY colleges)

Replace the splitter with the distribution amp rather than putting it in line like in your diagram, that will save you 3db or so of loss.
