About SMA vs. TNC, Have you ever observed the external antennas? <\/p>\n\n\n\n
The newly purchased antennas must match the radio interface; otherwise, they will not work correctly. <\/p>\n\n\n\n
You may think they are all the same, but you will see different antenna interfaces if you notice them closely. <\/p>\n\n\n\n
This article will introduce two commonly used antenna interfaces; SMA and TNC.<\/p>\n\n\n\n
RF connectors play an important role in any antenna system, functioning as a connection between the antenna and related RF systems. <\/p>\n\n\n\n
The antenna market deploys SMA and TNC RF connectors for a rugged connection with several variants, including reverse polarity, non-rotating, rotating, and male\/female options.<\/p>\n\n\n\n
People use RF connectors for several reasons, but the common ones are their inexpensive nature, capacity to handle different operating frequencies, RF power levels, and large mating cycles.<\/p>\n\n\n\n
