One if three will do much better for combining two signals. Using a regular splitter backwards will likely eat up most of the improvement you’d gain.
ok so I am late to the game and there were a lot of great questions and answers
I am going to try to pull them together and add my own part
​
first thing is you want to test the antenna and amp direct to the TV
so get a long piece of coax and if you have a small tv you can position near the opening of the attic that would be cool if not you need to run one long enough to reach your tv..
See if your setup works.. no splitters.
Next if it works you want to use the signal indicator on your tv to set the position of the antenna to its best direction for the best reception.. it might just be a nudge in any direction that you need for the best signal. Pick a weak station on your tvfool report to do this.. the strong ones you won't have problems with.
​
Ok so it works and you get good signal.. now your home's wiring.
If a splitter is used anywhere on the line from the injector to the antenna it will block the voltage getting to the antenna.. UNLESS its a bidirectional AND power passing splitter.. they are harder to find than you might think .. there are a ton for satelite dishes and you can screw yourself on those...

see how each port says in-out and its also DC/IR power passing on all ports? thats what you should look for.. it just makes life easier
​
to tell if you are getting power at your antenna its not hard you just need a voltage tester if you live near harborfreight you can get one free (with any purchase)

go up to the wire going into the antenna amplifier and test on the center wire and the outside screw on part.. you should get somewhere between 12 and 18volts DC.. make sure the tester is set on DC.
​
if you got that and your inserter is placed at your tv and its shooting power up to the amplifier then you should be getting signal..
​
like others have said you can also test without the amp and maybe thats fine.. just remove the inserter and go directly to the antenna in the attic instead of passing through the amp.
A dead amp or an amp that isn't getting power will shut down all signal from the antenna.. Its a good way to know your amp is dead if you get no signal .. but your amp is probably not dead.
a bad wire .. a bad crimp on a wire.. that can cause problems
I bought a Channel Master Preamp that came with a cable but the cable wasn't crimped correctly .. it was the small inserter cable from the power supply to the inserter.. so I replaced that and it worked fine.
so idk if i missed anything.. and others have touched on other things
​
good luck
I get 11 channels right next to Gainesville High School.:
I used to work at Gainesville Television Network. In order to pull in the stations above, you'll need an attic to put an antenna in - or you can mount one on the roof or outside pole.
Antenna 1: Amazon Basics clone of the Leaf antenna
Antenna 2: Clearstream 5
Combiner: Channel Plus Combiner/Splitter
Signal Booster: Motorola Signal Booster
Take those items and some lengths of RF cable (CATV style cable) and connect as such:
Cable from each antenna into the two ports labeled "IN" on the combiner.
One cable from the "OUT" labeled port of the combiner to the "RF Input" connector on the signal booster.
One cable from the signal booster "RF Output 1" to your TV.
One cable from the signal booster "Power 12vdc" connector to the included power adapter, which is then plugged into the wall for power.
This will pull in the above 11 stations nearly anywhere in Gainesville. Of course, your results may vary depending on your location and such.
>What kind of high quality splitter would you recommend?
Dunno really. You are mostly just avoiding the counterfeit ones. This one seems popular, but probably mostly because it is marked on the case for both splitting and combining:
>Also, if I go this route,,,how far should I space them? Or does that matter?
It apparently depends on the gain of the antennas. I think that most people won't have enough space on their mast to worry about it. Here is an appropriate search:
The 30-2476 seems to be the only high gain VHF-high antenna available right now for a reasonable price.
Sometimes no amount of antenna gain can make a weak signal reliable. Signal levels can vary a lot over time/season/weather.
Oh and I use one of these to combine my digital TV antenna signal and the one the modulator puts out.

I've seen devices that will selectively combine (or really replace) one channel on an antenna with the signal from another antenna. That's one option.
A friend of mine is using two antennas with a simpler combiner (he bought this one: antenna combiner) and he has had no complaints.
