SMA is an acronym for SubMiniature version A. It uses a threaded interface. Semi-precision 50 Ω SMA connectors provide excellent electrical performance from DC to 18 GHz although some 'general purpose' versions will not perform as well. SMA connectors are compact in size and mechanically have outstanding durability. SMA connectors can be mated with other SMA and APC-3.5 mm connectors.
SMA is available both in Standard and Reverse Polarity (RP) versions. Reverse polarity is a keying system accomplished with a reverse interface, and ensures that reverse polarity interface connectors do not mate with standard interface connectors. Most manufactures accomplish this by inserting female contacts into plugs and male contacts into jacks. Other manufacturers use reverse threading to accomplish reverse polarity keying.

PL-259 Quick Disconnects For Ham Radio Lightning Protection
A simple and inexpensive method to protect your ham radio investment from lightning damage is to install PL-259 / SO-239 - UHF 'Quick Disconnect" connectors. Doing this allows for quick removal of radio equipment from the coaxial cable feeding the antenna system. Quick disconnects are very reliable and as the name implies these are quickly installed or disconnected.
It's always a good practice to disconnect your radios from it's outside antenna system if you plan to be away from your ham station (QTH) during periods of unstable weather such as thunderstorms.
Many ham radios operators pay particular attention to the weather and as a result have advance warning of inclement weather. In fact, the amateur radio community is very active in the SkyWarn program which is a partnership between the National Weather Service and local communities.
You will find a large selection of UHF components at TestParts.com. TestParts is called 'America's RF Superstore' and one visit our their website will prove this. You will find an excellent UHF Quick Disconnect at TestParts for $3.95 each. TestParts SKU #97530.
