"The RTO" v2 Wearable Antenna (BNC-F to TNC-M Adapter)CAATail Antennas are handcrafted (USA), flexible antennas that are worn on the user's plate carrier or ruck. The antenna was designed and field tested around VHF UHF squad internal communications. The v2 model offers increased UHF performance and a triple abraded PET sleeve for extra cable protection. When configuring the antenna, route the cable either over your shoulder or along your cummerbund and make a "U" shape on the back of your plate carrier.
