They generate lots of PIM. Do a search for PIM and read all the info there.

In high power digital modulation schemes, antennas and connectors are now rated for PIM. TDMA modulation can generate several kilowatts of peak power in combined transmitter schemes. Even closely examin an N connector after it has been installed and removed? Lots of fine brass or silver "shavings" inside the connector. This is a breeding ground for PIM. 7/16 dins don't do this.

What property of N connectors generate IMD?
