Antenna DP1 LB is highly effective as a component for trunking and common repeaters with significant (up to 4 MHz) TX/RX separation. It is very handy for adjustment and installation due to its design. In spite of its dimensions antenna has high mechanical strength, provided by additional mounting brackets. You can refuse removing transmitter for a long distance from mast as an advantage of antenna power supply system. Antenna DP2 LB is two-level collinear antenna with high gain factor. Only girder masts suit for its installation. Dipoles, mounted on opposites sides of the antenna, provide possibility to produce practically circular directional pattern (with some loss of the gain). Antenna has wide operating bandwidth, as single-dipole antenna does. Equipped with TK-52LB adders.
