I've been putting it off mainly because I didn't want to remove the LCD Monitor I use as a TV display. It's been rattle free...so I've been procrastinating! Well...not anymore! With the proliferation of HD OTA signals floating around, I should be able to receive SOMETHING in many of the places I visit. Without some type of amplifier I had to be almost on top of the antenna to get any picture at all. Unlike old style Analog TV signals, Digital is an "all or nothing" affair. Either you have a nice picture or no picture at all! So I did some research and found a nice 25dB amplifier online for around $20.00. It's small, runs on 12 Volts and can be mounted almost anyplace.
So, here we go! Since I have A LOT of space behind my flat screen LCD monitor (the old CRT Tube-type TV took up MUCH more space, I try and install anything I don't have to get to easily behind it. (Of course, eventually I'll be adding some kind of hinge and latch assembly so it can actually be USED for additional storage.) First, figure out where you want to put the amplifier. It's best to find out where the antenna coax cable ends and locate it pretty close by. Make sure it will be easy to find 12 Volt power nearby as well. This may not be possible with your setup, so you may need to run power and/or coax cable around.
Disconnect your NON-POWERED antenna lead from your receiver or switch-box and connect it to the amplifier's IN terminal. Then run a new cable from the OUT terminal back to where you removed the original antenna cable. Sounds complicated, but really isn't. You may already have a power switch for an amplifier installed, if not....buy one! You should NOT leave this connected 24/7 as it will be a drain on your batteries. Connect the ground wire to ground (DUH!) and then run the power lead from the amplifier to the switch. You can use crimp-on terminals or you could solder it on.

My switch was also internally lit, so it required a little bit more wiring so it would actually LIGHT up when it was on. This way I don;t forget to turn it off when I'm done using it. (Don't ask...)
Then affix the amplifier to a convenient spot using two small screws. I used self tapping wood screws as it was the easiest. The amplifier is only a few ounces, so they will be more than strong enough, even with all the road vibrations.
I cannot stress this enough:
TEST THE INSTALLATION BEFORE YOU CLOSE EVERYTHING UP!!!
I ended up re-opening everything, because I forgot to tighten the coax connections and tape the connections.
Results? Not too bad. In the location that I am parked, I was getting ZERO channels with my digital TV receiver. Now I have four. Hey, it's better than none, right? I imagine if the RV was turned (the antenna is FIXED in place), I could get more. Hmmm...How about figuring out a way to be able to rotate the antenna?? Maybe in a year or two!
The picture looks really nice in HD coming from the digital receiver. I have the audio going through the stereo system. Sounds great and uses very little power.
If you have an antenna and it ISN'T connected to a powered amplifier, this is a really nice retrofit. Don't be scared of the lengthy instructions. It was very simple. if you have access to the wiring without taking your RV apart, it will go much faster.
