The dual and quad links from TrueRC.com are an easy way to connect multiple antennas of the same frequency (1280MHz only) together for increased performance. By using 4 antennas, you will make your own Gatling; a long-range antenna with very high gain but a narrow beam. If you use the dual link, you'll be making a pepperbox which has 3dB less than the Gatling, but a much wider beam width and reduce the need for an antenna tracker.
Taken from TrueRC's website: Dual Link: Here's yet a new thing at TrueRC: The 1280MHz "dual-link". Like the quad-link, but to match two antennas instead of four. I made it for an interesting use: To convert a Gatling into a pepperbox antenna by replacing part of the matching network. Just unscrew either the two left or two right elements and screw the dual-link. (be sure to mark your connector to put them back at the same place.) Your Gatling will then turn into a 13dB pepperbox, useful at the field in case your tracker let you down. Quad Link: Matching network to link four antennas together for increased gain (5-6dB). Coax from antennas must be exact same length. Place four antennas 9 1/4" apart center to center, forming a square.

No, these are designed for two like patch antennas (i.e. a pair or 4 crosshairs)
you would need a separate receiver and diversity switcher for an Omni and patch combo.
