Hi guys, today i got my new antenna for my goggles ( i have the cheap ev800, i know they are cheap but i won't invest for new goggles for now), i just wanted to replace the stock one with a lumenier axii long range, but when i did the test it was so bad vs the stock one for some reason, i tested if the lumenier antenna work and it does but after going 10 meters away from it get way low signal....
it more long range the stock than the luminier...
did i do something bad or what?
btw i have a nazgul evoque f5d 6s (600mw vtw power)

frank lichen Apr 7, 2023, 10:19 PM

#

i got an adaptor to get it in, cuz the antenna has a male SMA and same for the goggles

#

and yes they were all in

the adapter is probably the problem here

#

but my EV800Ds have the female SMA

frank lichen Apr 7, 2023, 10:20 PM

#

green snow Apr 7, 2023, 10:21 PM

#

frank lichen Apr 7, 2023, 10:21 PM

#

frank lichen my first goggles btw and i regret that i didn't get the one with 2

#

frank lichen Apr 7, 2023, 10:21 PM

#

green snow Apr 7, 2023, 10:21 PM

#

#

#

the right one is the antenna and the left is the adaptor

green snow Apr 7, 2023, 10:23 PM

#

ohhhh your antenna is RP-SMA

frank lichen Apr 7, 2023, 10:24 PM

#

ye i really didn't get how the male and female works 😅

#

i always say male has the thing and female the hole

#

but sma works different for some reason

green snow Apr 7, 2023, 10:24 PM

#

yea adapters sometimes dont work right

frank lichen Apr 7, 2023, 10:25 PM

#

so the adapter is the problem?

green snow Apr 7, 2023, 10:25 PM

#

probably

sweet plinth Apr 7, 2023, 10:25 PM

#

oh its just the D so it wouldnt have 2 spots for it

green snow Apr 7, 2023, 10:25 PM

#

I think what you need is a RP-SMA male to SMA female

#

wait a minute

#

oh im the dumb one here that is SMA male and the goggles are RP-SMA female

#

interesting

frank lichen Apr 7, 2023, 10:27 PM

#

i don't know why the antenna as the same SMA of the drone itself

#

Probably cuz modules have those sma connector?

green snow Apr 7, 2023, 10:27 PM

#

why would they have SMA on the EV800Ds and RP-SMA on the EV800s

#

thats stupid

frank lichen Apr 7, 2023, 10:28 PM

#

Oh it fit on the D?

green snow Apr 7, 2023, 10:28 PM

green snow

ye

green snow Apr 7, 2023, 10:30 PM

#

well trying another adapter might fix your problem

#

looks like what you would want is a SMA Female to RP-SMA male

frank lichen Apr 7, 2023, 10:30 PM

#

i went back on ebay where i bought the adapter

#

it say SMA female to RP:SMA male

#

idk, i might do some test

#

btw thanks for the help 😄

#

frank lichen it say SMA female to RP:SMA male

that should work…

#

ur goggles r rp-sma female

#

so that connects to the rpsma male

#

and then the sma female in the adapter should connect to the sma male of the antennas

green snow Apr 10, 2023, 2:45 AM

#

well its the right adapter but I've had issues with adapters not working
