The kids really love it and we have people who drive their whole family to the house to see my Witch fly. I changed it up this year and made a ghost. I'm on a corner so I can zoom up and down my property and it's seen a long ways.
The ghost was much harder to do than my witch and I'll probably go back to the witch just because its so easy to set up.
I use 1.3 on all my long range flights and have a couple of stacked skew planar's for omni direction and a helical and patch.
I have a tracking antenna with 900 mhz patches and 2.4 yagi's for Xbee telemetry but don't use it very much except on one dedicated airplane.
I feed the video to a diversity box which selects the best signal from quality alone not RSSI.
