Purchased these before I understood the connector "terminology". They have performed fine and I am selling to get a set that match my TX/RC. These have a center pin where as I need a female receptor. To dig myself in deeper I next bought adapters to match my Boscam 832 set. But I don't like the use of adapters for fear of signal degradation, regardless of how little it is. Also I popped the cover off the antenna on my receiver to see whats in there and broke the little tabs of the cover trying to get back on. They don't look that complicated, but assume it all means something. Will sell for $20, $5 shipping and $6 for the 2 adapters if you want to go route I took.
