Interested to see results, my personal view is that amplifier will do nothing in this setup, only degrade, unless they are placed at the antenna to compensate for loss through coax, connectors etc.... it may be worth putting your heltec filter on the amps input.
@bryan but is it not important how long your coax is? Loss is there, but otherwise you have to put a non waterproof amp outside.. you know what I mean. Building a enclosure etc. etc.
@@Righttorepair880 not how it works.... amps introduce noise, and also amplify noise, they are not selective, if you put an amp away from the source it will amplify the degraded signal Inc noise, you will be worse off.... and yes, an amp can and does make things worse if located in the wrong place, you are better off without it if you can't place it next to antenna output....
SPF5189Z present a very low Z at output..you have to see the power current not more then 120mA...I found is woring better with lower ..like 100..don't worry about the low inpendance..check the current.
Reverse Polarity is when a receptacle is wired backward. This happens when the “hot” wire, also known as the black or red wire, is wired on the neutral side and the neutral wire is wired on the “hot” side.
Waiting for the results
Not later then a week..
Bravo, more testing please
Comin'...
Waiting for the results😁
Soon..
@@viocaia hope it works keep posting bro love it

Still worth a try..now I have a good setup so I can have a clear image.
I'll try that in the second test..and third.. filter in and out of amplifier..

@@Righttorepair880 Of course..but it's always a balance between feed line and signals..we have to find a proper one..

What happened to AirBuddy? Did you tested it?(with miner)
would like to know this to!
results soon..I need few days fro a proper idea..
If current is sent from the miner (beacon) won't it burn the amplifier?
Maybe that's why he had to repair it! 🤣🤣🤣
No..I already test that in a previous video..check for that..
Im trying to repair a broken board so i soldered in the new spf5189z and now vcc and gnd appear to be shorted? Can this be normal?

@@viocaia hello, my board seems to draw 130ma. How can i limit the current? Thanks for your help
Kind of ok for ''fakes'' SPF..you can add a 10ohms resistor to ''cool'' it down..from plus adapter to plus amplifier..
@@viocaia makes sense thank you a lot!!
@@user-mm4zs5ts9i Any time!
Reverse polarity?
