This bow-tie antenna kit is suitable for use with our 10mW 2.4GHz Audio Video Transmitter / Receiver kit (K229). The antenna was tested with our 2.4GHZ  TX / RX kit and gave good quality reception at just over 100M in a industrial estate just over 100M wide. This was as far as we could easily test the units over. We are confident that it has much better range. Kit includes PCB and case.
