The UA874 antenna uses a log periodic dipole which provides a cardioid directivity towards the desired coverage area while providing better rejection of RF signals outside this area compared to an omnidirectional 1/2 wave standrad antenna. The integrated amplifier provides four gain settings to compensate for different levels of signal loss from the coaxial cable.
The UA874 antenna can be mounted on a stand, suspended from the ceiling or fixed to the wall by means of its integrated articulated bracket.
