Nano RX or Lite RX

What is the major difference between Nano receiver and Lite receiver?

Nano receiver (2.4G version) is the first and (so far) the only receiver with power amplifier (PA+LNA). It has 100mW telemetry output and better sensitivity when longer range. Lite receiver doesn’t have a PA/LNA on them, so its telemetry power is as what the RF chip SX1280 came with 17mW.

Beside, Nano receiver comes with normal external Dipole T antenna. Lite receiver has SMD ceramic antenna and in theory it is not so long range.

High recommend the Nano receiver if the space is enough. On 65-85mm whoop drones with limited space and need light weight, Lite receiver is a better choice.

Tower Antenna or Flat Antenna

New lite receiver with a flat antenna features a 3mm extra-thin board and 0.53g lightweight, which requires less assembly space on drones with limited space. Besides, solid flat antenna without irregular parts can withstand crashes, making the receiver not so fragile.

Whatever tower antenna or flat antenna, both versions perform well in control, range and stability, bringing a good flight experience to pilots. Below chart is the basic information for two antennas. It is shown that both antennas have almost the same performance in gain. However, the efficiency for flat antenna is better than tower antenna. In spite of that, tower antenna and flat antenna V1.1 can reach about 600 meters by equal conditions.
