UA874 uses a log periodic dipole array to produce a cardioid pattern towards the desired coverage area with greater rejection of RF signals outside the coverage area when compared to standard ½ wave omnidirectional antennas. An integrated amplifier with four gain settings compensate for varying degrees of coaxial cable signal loss.
The UA874 can be stand-mounted, suspended from the ceiling, or wall-mounted using the included swivel adapter bracket.
UA874 is available in different versions:
-
- UA874V = 174 – 216 MHz
- UA874E = 470 – 790 MHz
- UA874WB = 470 – 900 MHz
- UA874Z17 = 1492-1525 MHz
- UA874Z18 = 1785-1805 MHz
