High Gain Antenna Kit
The Shure ® PA805 (Figure 10) is a directional antenna for
increased range and reduced interference. The “gain” of this
antenna enables it to receive signals from a greater distance than
at typical “whip” type antenna. The antenna allows for increased
performance of wireless microphones with 6 db of gain. The
directional antennas may be located up to 50' (15.2 m) away from
the announcer’s rack.
