Shure HA-4540 PWS Tour Series Helical Antenna

The HA-4540 Tour Series helical antenna delivers dropout free RF performance in a lower profile housing that packs and stores easily, which suits touring productions and any installation where space is limited. Like other helical designs it can serve as a transmit or receive antenna for wireless microphone and personal monitor systems, giving reliable coverage without the polarization sensitivity of a plain whip antenna.
