We are finding it difficult to establish a good relationship with any provider of RFID readers and tags. Our application requires a reliable reading range of 5 meters (16.4 feet). Any suggestions?

Oliver,

Achieving 5 meters of read range with animal ear tags would be difficult, which might be the reason solution providers are not engaging with you. Such tags often use passive low-frequency (LF) or passive high-frequency (HF) transponders, which have a maximum read range of about 3 feet.

There are passive ultrahigh-frequency (UHF) ear tags, such as GOA RFID’s 860–960 MHz Livestock RFID Tags, but the transponder in an ear tag must be relatively small, which limits the read range. GOA RFID’s tags have a read range of about 3 meters (9.8 feet). You might need to adapt your solution so that it will work with such a range.
