LoRa Antenna Frequencies
Antenna gain
It is worth noting that a high-gain LoRa antenna will give you the best witness returns, but there are many LoRa antenna designs to choose from.
Omnidirectional antennas VS Direction antennas
The Advantages and Disadvantages of High Gain LoRa Antennas
Hence high gain Lora antennas will let you achieve longer ranges and better signal quality as far as Lora communication is concerned. However, you have to aim precisely in the receiving antenna direction to accomplish this. On the other hand, low gain antennas have a shorter range, they hence do not focus a lot on the direction of the antenna.

RF connector
N Connectors
The Type N connector is a threaded weatherproof, medium-sized connector for durable applications that can easily handle frequencies up to 11 GHz. This type of connector follows MIL-STD-348 and is widely used in lower frequency microwave systems where ruggedness and low cost are needed.
SMA Connectors
The SMA (SubMiniature version A) connectors are semi-precision coaxial RF connectors operating up to 18 GHz, though some proprietary versions are rated to 26.5 GHz. It is commonly used in RF power amplifiers, RF isolators, microwave systems, mobile telephone antennas, Wi-Fi antenna systems, and radio astronomy at 5 GHz+. It is mostly used in indoor solutions as it is not sufficiently weather-proof for outdoor deployments.
RP-SMA Connectors
The same as SMA but with reversed polarity Reverse-polarity SMA (RP-SMA) is a variation of the SMA connector specification that reverses the gender of the interface. The term "reverse polarity" here refers only to the gender of the connector's contact pin, not in any way to the signal polarity. It is suitable for indoor solutions.
