What interface is ANT?

Antenna hardware interface ANT is the antenna interface, used to connect the antenna. Commonly found on radios, or GPS, etc. An external antenna is required when receiving shortwave or FM to increase reception sensitivity.

The antenna interface of SMA should be SMA, and SMA and RP-SMA are different. There are many types of SMA. The difference in polarity is that one is called "SMA" and the other is called "RP-SMA". The difference between them is: the standard SMA is: "externally threaded hole", "internally threaded needle", RP-SMA is: "Externally threaded needle", "Internally threaded hole".

The antenna interface is an interface end of the wireless device.

The antennas of the wireless devices themselves have a certain distance limit. When the distance exceeds this limit, these external antennas must be used to enhance the wireless signal to extend the transmission distance. There are three concepts involved here:

1. Frequency range It refers to the frequency band in which the antenna works. This parameter determines which wireless standard wireless device it applies to. For example, 802.11a standard wireless equipment requires an antenna with a frequency range of 5GHz to match, so when purchasing an antenna, be sure to look for the corresponding product with this parameter.

2. Gain value This parameter represents the antenna power amplification factor. The larger the value, the greater the signal amplification factor. That is to say, when the gain value is larger, the signal is stronger and the transmission quality is better.

3. Antenna interface is mainly for wireless devices that can be disassembled and connected to external antennas. Correctly match the corresponding antennas for different interfaces to increase the signal and extend the distance.

Common interfaces of antennas:

Antenna with SMA interface: The full name of the SMA antenna interface should be SMA reversing male connector, that is, the antenna connector has threads inside and the inner contacts are pins ( One end of the wireless device is threaded on the outside and the contacts are tubes inside). Wireless devices with this interface are the most popular. More than 70% of APs, wireless routers, and more than 90% of PCI interface wireless network cards use this interface. This interface is moderately sized, and many devices such as handheld walkie-talkies also use this interface. type, but the needles and tubes inside are the opposite of wireless devices. Wireless APs and wireless routers using this interface include most civilian equipment. TP-LINK, DLINK, Netgear, Belkin and other brands basically use this interface as long as the antenna is detachable. The antenna interface of SMA should be SMA, and SMA and RP-SMA are different. There are many types of SMA. The difference in polarity is that one is called "SMA" and the other is called "RP-SMA". The difference between them is: the standard SMA is: "externally threaded hole", "internally threaded needle", RP-SMA is: "Externally threaded needle", "Internally threaded hole".

TNC interface antenna: The full name of TNC antenna interface should be TNC reversing male connector, which is thicker than SMA. There is a layer of metal shielding between the external and internal contacts of the antenna connector. The most typical one is the network Most of the wireless devices of CISCO and its sub-brand LINKSYS use this interface. The exceptions are the two wireless bridges WET11 and WMP54G, which are SMA. In addition, the two cheaper gain antennas, 5dbi omnidirectional and 9dbi directional, are CISCO's spare parts, because CISCO's APs are sold without antennas, which is different from home APs.

MMCX interface antenna: It is more common in APs and wireless routers with built-in PCMCIA interface wireless network cards. There are two types of transmitting parts of APs and wireless routers. One is a wireless network card. This card is usually PCMCIA (there are also MINIPCI’s). In addition, there are also wireless transmitting modules, such as MSI's pure AP, LINKSYS's 11S4 wireless router, etc.
