+My suggestion is to buy **CF816** Fixed reader. **CF816** and **CF811** are basically the same, the main difference is that **CF816** is using impinj E710 chip, which is more sensitive in reading and has a higher reading speed. **CF816** also has more API commands than **CF811**.\\
+**CF800** is also using impinj E710 chip and has Android operating system additionally, which I think is not necessary to us. The API of the **CF816** and **CF800** are the same.
+And buying two to four **CF-RA8080** UHF RFID ceramic antennas to use with the Fixed reader, The gate size of the chicken house is around 30cm height and 27cm width. The ceramic has a size of 80*80*5mm, with circular polarization, its reading angle is 60 degrees forward. So it is possible to cover the gate size. But we can also go for a PCB antenna. For PCB antennas, I suggest **CF-RA5005** UHF 5dBi Counter Antenna, also with circular polarization (120*120*6.5mm).

+Fig.1 CF-RA8080 (Left) CF-RA5005 (Right)
+**CF-RA6005** UHF Narrow Angle Beam Antenna fits the gate width perfectly, but it is not waterproof.
+And two **CF661** integrated readers, with a read range 0-6 meters. Prime reader and Fast reader are using the same SDK.
-The main difference between CF811 and CF816 is that CF816 is made by impinj E710 chip, so it can read more tags per second and more reading sensitivity than CF811.
