Signal lost after installing sh-2500 2.4ghz amplifier

[Daniel.p4]

Signal quality bad after putting on 2.5 watts sunhans boosters. Does better when I attach just the antennas. Any ideas?

Not to sure on this set up but you know your remote should have those brass gold plated ends inside those silver chrome antenna holes with nut on top to secure them so wire not get moved around or plug torn out of board,,,I just have quick look but me think these need power source to work,

 

[Daniel.p4]

Yes that is just to show the equipment and I'm experimenting. The sunhans are powered by a 3s lipo 5200mah.

 

[Daniel.p4]

Maybe a relink will resolve the issue. Is it necessary to relink after installing sh-2500?

Screenshots of pictured setups signal strength.

And I did perform a relink preflight.

 

[Daniel.p4]

Switched back to antenna only. Relinked and get this.

Is it possible when you got that bad channel 13 on auto,,what happen when you select custom and choose a channel,,does it stay the same,,auto is finding channel for you but manual you can select one

 

[Daniel.p4]

It just cuts out the same on manual

Gezz tricky one,,tryed change the 2 top antenna ones around,,does that do anything,,looks like set up good so running out of ideas,,

Modifying a cable until I can order the right combination mmcx sma male. Only thing I can thing is signal loss due the excessive connections and wire length.

I do believe that your On the right track.....even that male to female connection is a great Db loss in top coax in the picture and yes plus the excessive length too is Not Good that is cause its usually the coax length that is a part of the antenna tuning /loading ....i believe its called resonate ( correct me is I be wrong Thanks)
Plus.......... after all the great ideas from ianzone......just might have some weak / bad Rf Amplifiers !

Good Luck and let us all know what you finally do to get the system working OK !

I tryed to correct all my mistakes LOL

 

[Daniel.p4]

Looks a hot mess

Daniel.......Only because you First said it.....Yes I agree.

Is it still under a years warranty ? (the craft and RC unit)

 

[Daniel.p4]

I void all warranties. I take everything I get apart. Its still a work in progress.

I forgot to plug the left stick in and tested it.. Let's just say I made a good attempt at landing without the left stick and some how put it down without damage. Landed upside down

Cool ,,,I think you should dismantle all,,have a big coffee and reassemble, yes cable lengths look like something I would do,,bit overkill,it's hard though not having bits to use,,we make do with what we have,I think you'll get there
