Hi guys,i bought this hardware for my my outdoor antenna, but i'm confused these seems to be 2 antenna amps? or the white with the power supply is an inside power inserter? https://www.amazon.com/Winegard-LNA-.../dp/B00DQN3R9O

amplifier bolts to antenna and power supply at tv end between tv and antenna wire . -
Re: Winegard-LNA-200-Preamplifier-Antenna-Amplifier
The black unit with the two F's and waterproof is the amplifier that should be placed near the feed point on the antenna. The white unit with two F's is the power inserter which is not waterproof and should be indoors. The thing that plugs into the wall is the power supply.Comment

Thanks guys for the info,i only asked because i have seen people use only the white inserter with power supply by itself inside as an amp,{See Link bellow} i already installed it the way you said and it works great, i have the best reception i 've ever had here in Boston area 60 miles away.

Re: Winegard-LNA-200-Preamplifier-Antenna-Amplifier
There are different ways to do this but the best place to put the amplifier is at the feed point, not near the TV. There are probably some crappy TVs that don't have or have weak RF amplifier stages that could benefit from any amplifier anywhere, but it's not optimal.Comment

Who knows what's in those things. It may or may not have another amplifier. Also the DC offset it introduces may affect the receiver stage. The coupling from the power lines could also add to signal strength. So it's hard to know definitively what's going on, from hidden amplification stages, offset effects, injection, and of course the placebo effect.Last edited by eccerr0r; 11-10-2021, 03:11 PM.Comment

Re: Winegard-LNA-200-Preamplifier-Antenna-Amplifier
Thanks mate, appreciate your explanation and your great expertise. I have it installed just like suggested. LNA 200 near ant. and LNA 100 in the cellar 100 feet from ant. and 10 feet from Tv, Works great. If i was younger i sure would go up there to the roof 30 feet high and just would try antenna connected just with LNA 100 only, but at my age i already did too much 1 time, hope i don't have to go up there for the rest of my life, i already took precautions for that, installed matching transformer and Amp 200 LNA inside weather prove box attached to the ant. mast .Last edited by ivtec; 11-11-2021, 10:35 AM.Comment

The lna-200 is meant for use with an outdoor antenna to boost the signal from the antenna to the tv, The lna-100 is meant for use with an indoor and not to be used together, The white power inserter (for the lna-200) has no amplification, it is just to insert the dc voltage onto the cable going up to the amplifier and it also blocks the dc from going into the TV's rf input.
The white LNA-100 does not supply voltage out the R.F. connector, it is a stand alone signal amplifier.

Vizio e601i-A3 - Has Sound and Display, But No Backlight - Bad Power Supply Board or Bad LED Bulbs ?I was given this TV from my great uncle. He said it just wouldn't turn on one day out of nowhere, replaced the TV, and gave it to me to possibly fix and use for myself.
Upon bringing it home and plugging it up, it showed a standby light.
I powered it on and without a flashlight, the display showed the "V" but the lighting is very dim, but visible.
The screen seems to blackout and stay black, but with a flashlight I can see the display.
With my Playstation 4 connected via HDMI, and running a game I can hear sound.

I have wanting to do this project for quite sometime now and I finally found a switching power supply that will work on this desoldering gun station ZD-915 that the original switching power supply took a shit and just was not worth trying to fix it because this switching power is not quite big enough to handle the heater element and the vacuum pump
One note when I tested the switching power supply and the voltage control board I noticed that this desoldering gun heat up much faster than the original switching power supply which I was really surprised by to the point that I might buy... -
I have been working on this concept for quite some time now with limited success but recently I found a switching power supply that is setup for the voltage that this soldering station needs to operate at however it also needs part of the secondary circuit from the original switching power because you need several voltage rails
I once tried to get a ZD-915 desoldering station to work on a 18 volt battery power supply but unfortunately things did not go well but I did find a work around but I might try this idea again but going at a little differently more about this another time... -
The sub developed a constant popping every couple seconds from woofer and power LED flickering with nothing but wall AC connected. Connecting an audio cable didn't change anything. It doesn't play but a second or two of audio in between the pops.
Opened it up and discovered the power supply is making a faint clicking or ticking sound.
I measured the amp's output to the woofer and it pulses up to 50mv DC to be driver. The pulses coincide with the power supply ticking/clicking.
I measured the power supply output going to the amp board and it too has this pulsing. Voltage cycles... -
Recently I switched from my Gray-Hoverman to the Antennas Direct ClearStream 4 MAX. Seems to work about as well as the old G-H in my attic (one-story ranch home), but the Antennas Direct unit can be mounted outside on my chimney if desired.
I should mention that I was also using a 29-inch "T" shaped antenna for RF channel 11. I know you're not supposed to use TWO antennas unless they have the same length coaxial cable going into your combiner (and even then there might be problems). So I made sure the cables were equal length.
Years ago I made a "T"...
