Is SMA better than BNC?
The SMA is better at resisting water intrusion than the BNC and is the most popular style connection on most 2-way radios. For a free-wide connection, such as to an external antenna, yes the BNC is a better choice but it isn;t something that an SMA to BNC adapter wouldn't solve.

SMA is much more mechanically convenient but has lower power rating compared to N. I assume you are operating under tens of Watts when I suggest SMA. If you look at the minicircuits catalog, their N connector attenuators are rated to 6 GHz and the SMA ones are rated to 18 GHz.
Is N connector same as SMA?
An additional advantage of type-N connectors is that they are meant to be hand-tightened, whereas SMA connectors should be tightened with a torque wrench to achieve the best performance. The main advantage of the SMA connector seems to be size, since it's quite a bit smaller.
What is a 2.9 mm connector?
SMA 2.9 also called "K" or "2.92 mm" connector was developped in the 1980's and is standardized per IEC 61169-35. Intermateable with SMA and SMA3. 5, SMA 2.9 is used for test and measurement and for high frequency microwave modules.

What's the difference between SMA and RP SMA?
The RP-SMA female socket has a barrel with external threads and a centre pin. When they are plugged, the two are indistinguishable and the signal quality is the same. Although an RP-SMA plug fits mechanically into an SMA socket, it does not fit electronically. Such a connection is therefore not functional.
