Dipole antenna DS2 ALT was designed specifically to operate through duplex filter on one feeder in receiving (300-310 MHz) and one in transmitting (336-346 MHz) frequency section, preserving circular pattern.
DS4 ALT and DS8 ALT antennas represent array antenna with increased gain, built using two or four DS2 ALT dipole pairs combined by adders. Such combination of several antennas DS2 ALT on one mast raises gain factor on receiving and transmitting section simultaneously. These antennas are essential for multichannel trunking systems, when TX-TX decoupling is need at the expense of vertical diversion.
