I use these connectors to connect an antenna on my FatShark ImmersionRC Black Pearl 7 "screen. Perfect signal, I did not see any particular problem. I recommend for this type of use.
I had doubts in this adapter commander saw the reviews, needing only one I ordered and I received a bag with 2 adapters. I now use and nothing to report, I recommend!
A single connector instead of two in the envelope! So unit price doubled. Do not buy from the seller, since I am not the first to have this unpleasant surprise.
