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). {{projects:rfid:antennas.jpeg?200}}\\ 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. ===== Wing Tags ===== | | Seller | Wing Tags | | | 1 | [[https://www.datamars.co.uk/game-and-poultry?page=4|Game and Poultry]] | {{projects:rfid:game_poultry_2022_flyer.pdf}} | {{projects:rfid:game_poultry_catalogue_2025_euro_direct_-_english.pdf}} | | 2 | | [[https://www.datamars.co.uk/product-page/wonderband| Wonderband]] | | | 3 | | [[https://www.datamars.co.uk/product-page/ccc-tag|CCC Tag]] | | | 4 | | [[https://www.datamars.co.uk/product-page/offset-cct-tag|Offset CCT Tag]] | | | 5 | [[https://www.aliexpress.com/store/5621012|Marc RFID Store]] | | | | 6 | [[https://www.aliexpress.com/item/1005006211960256.html?srcSns=sns_WhatsApp&spreadType=socialShare&bizType=ProductDetail&social_params=60804826897&aff_fcid=e689edffc04d45ea801dcf6ba172f671-1730714897567-09218-_Ez0yeW5&tt=MG&aff_fsk=_Ez0yeW5&aff_platform=default&sk=_Ez0yeW5&aff_trace_key=e689edffc04d45ea801dcf6ba172f671-1730714897567-09218-_Ez0yeW5&shareId=60804826897&businessType=ProductDetail&platform=AE&terminal_id=777d0d9ec8b441acadffa0c95a3e58ce&afSmartRedirect=y|water washing tags]] | | | | 7 | [[https://www.aliexpress.com/item/1005004448714050.html?spm=a2g0o.productlist.0.0.66bb2989fCP8t3&mp=1|RFID UHF foot ring tags]] | | | | 8 | [[https://eshineboon2022.en.made-in-china.com/product/vJKpXTeGauWr/China-Poultry-Identification-Tags-Bird-Duck-Quail-Chicken-Wings-Identifier-Poultry-Farm-Chick-Wing-Tag.html?pv_id=1ibrr4lts782&faw_id=1ibrr54bs9a7|Made-in-China]] | {{projects:rfid:wing_tag.jpeg?150}}{{projects:rfid:wing_tag_pliers.jpeg?150}} | | | 9 | [[https://en.made-in-china.com/?acc=8642081837-lxy&cpn=37018752-1259367162&tgt=kwd-20370971&net=g&dev=c-&gid=CjwKCAiA5Ka9BhB5EiwA1ZVtvGZSCyLKepEwaXjePqXqsoteDmZifErGKgI08QP2Eks29jFwimhbfhoCY0MQAvD_BwE&kwd=made%20in%20china&mtp=b&loc=9043781-&gad_source=1&gclid=CjwKCAiA5Ka9BhB5EiwA1ZVtvGZSCyLKepEwaXjePqXqsoteDmZifErGKgI08QP2Eks29jFwimhbfhoCY0MQAvD_BwE|Made-in-China]]\\ Customization | {{projects:rfid:customize_tag.jpg?100}} | | | 10 | [[https://www.caisley.de/en/|Caisley]] | | | | 11 | [[https://www.nationalband.com/poultry-bands/|National Band & Tag Company]] | [[https://www.nationalband.com/jiffy-893/|{{https://www.nationalband.com/wp-content/uploads/2019/06/jiffy_band.jpg?250}}]] \\ Jiffy Style Wing Tags\\ {{projects:rfid:jiffy_style_wing_tag.jpg?250}} | {{youtube>4u_0VkPk5_A?medium}} \\ Wing Banding Directions -
