Product Information

The UPA3 series antenna was designed specifically for the purpose of on-site radio paging systems. It consists of two half wave dipoles at 90 degrees of each other and fed in phase with a matching harness. This antenna is very robust and can withstand the harshest environmental conditions. The antenna can easily be installed and with a bandwidth of 25MHz, it can operate both on transmit or receive frequencies without loss of performance.
