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.

The cellular industry like them, as they generate less intermodulation

for amateur radio.

What property of N connectors generate IMD?
