Telex BTR-300-71276
VHF Wireless Intercom Base Station, BTR300-71276

BTR-300-71276

VHF Wireless intercom base station. Single channel, fixed crystal intercom base station supports up to four full time transmit, full duplex beltpacks (TR-300). Four base stations can be used together in one location to support up to 16 beltpacks in simultaneous operation. This is a great choice when budget is the primary concern, but you cannot do without high quality RF performance.

BTR-300-71276 Features
