When I ordered my 2014 Y6 (fully assembled) I purchased the full OSD/FPV kit and FPV monitor from 3D Robotics. To avoid any issues.
Have it set up where I am using the "dual" receiver on the Monitor, not the receiver that came with the kit.
Well, to put it nicely, my FPV stinks. Start getting a pretty broken signal at <100 feet. So I decide to upgrade the antenna's, opting for Immersion RC. Reading all, or lots, of the RP-SMA v. SMA posts, I carefully research that 3DR uses RP-SMA on their kit. Get the antenna's and it may actually be worse.
So today I am re-reading the Monitor User Guide and the specs clearly list it has having 2 SMA antenna's.
I am not expert, but I do believe that SMA & RP-SMA are not compatable.
So I 3D Robotics actually selling and FPV Monitor, with their name on it, that is not compatible with their FPV kit?
Thanks.

Sma male has thread on inside with a center pin. Sma female has thread on outside with no center pin. They fit together.
Rp-sma male has thread on inside with no center pin. While the rp-sma female has threads on outside with a center pin.
The wiki has an explanation: http://en.wikipedia.org/wiki/SMA_connector
RP just means it's a SMA connector with a reverse polarity center conductor, the outside is basically the same between the two. Make sure to look at the inside of the connectors you have to verify that the center wire is only on one side. If you have 2 center wires (or none) things could have been damaged.
Set the monitors receivers band to "E" though it's setup menu, and verify the channel settings on the transmitter, the sticker is on the silver receiver for the dip switch settings. The default is channel 8.
