Question: If i only plug in the power injector and not the pre-amp with fm trap will it still improve my signal?
Document: Then run a wire from the output/power port into the house. In the house, you need to attach the power inserter on the coax line to power the pre-amp. From their, you can plug the coax into the TV.The pre-amp has a built in FM trap to reduce interference.
Item seems to work great I live in a rural area and am able to pick up stations at 60 miles that I was only able to inconsistently problem with this is that after tightening the f connector from the cable to the pre amp am not able to remove the cable as the device is broken inside now I have to cut the cable replace 50' cable and order a new amp this amp can be used as a combined UHF and VHF combined and/or for separate signals as well a s a fm trap.
BTW...this pre-amp has a capability of attaching a second TV antenna just in case I have another one for FM radio or another antenna pointing to another direction of the compass. I'm glad that I did not buy the other brand that is around $25 more than this RCA pre-amp, and I hope the small step-down plug-in converter will last more than 3-years along with this constant lightnings and electrical power spikes here in Houston.
Still no luck. My final effort was to unplug everything in hopes of possibly resetting something. When I plugged it all back in and then performed a program search nothing improved. In fact, when I unplugged the preamp, it didn't even register a change in signal strength. It made no difference at all whether plugged or unplugged!! The only thing I noticed was that the power pack on the plug was warm to the touch when left plugged in for just a few minutes.
From the attic mounted power injector I stretched about 65 feet of new RG6 cable and subsequently attached a two-way splitter at second-floor-level with an additional 50 feet of cable from each split. The unit works much better if the power injector is in line before the Splitters, and the attic was the overall best fit for a convenient plug-in.
I had thrown out all the packaging, so returning to Amazon might not be an option - I'll have to contact RCA.Update 10/18 - After some back and forth with RCA, they sent me a replacement free of any charges, and the pre-amp worked as expected. It took some prodding - as their first response was that I might not need an amplifier and the signal is too strong for the receiver. Definitely a possibility - but the hot output still wouldn't happen in that case.
Took a lot longer to install than I anticipated (I work in IT, so installing a signal amplifier isn't outside of my ballpark), but once I got it set up correctly, it worked amazing! Extra channels (not a huge concern because I had everything I wanted) and a LOT better quality on every channel. I would definitely recommend.pointers for installation:* don't put the power supply on too long of a cable run from the pre-amp.
I split an antenna signal three ways. Using this amplifier helped keep the signal strength high on all televisions. Make sure you hook the amplifier up in the correct order : Antenna, amplifier(the one in the picture), splitter, power injector, television.
Our big ol' attic antenna needed some help so I added this to the loop. It has an optional power injector/amplifier that actually degraded the signal when I plugged it in.I cannot explain it, but at this point, if it ain't broke I ain't going back up in the attic to fix it.
Same for using split inputs. Again, put the FM trap in to start, then remove it and compare results (to make sure FM isn't overloading the system). Also, you CANNOT insert a splitter between power supply and the preamplifier as this will short out the PSU and the preamp won't receive any power (in which case you won't get anything). Inserting a ground block or barrel splice between amp and PSU is ok though.
Answer: Probably not. The power injector powers the pre-amp. I wouldn't try it, even for giggles. It's low voltage, but the power would be sent somewhere. You might cause a rip in the space-time continuum.
