The HA-4540 is a Tour Series (TS) helical antenna that gives dropout-free RF performance in a lower profile for easy storage, made for touring productions and any application that needs a compact size.
The HA-4540 covers 460 to 900 MHz with an on-axis gain of 7 to 9 dBi and a beamwidth of 72 degrees, matching the gain and circular polarization of the HA-8091 domed helical antenna.
A helical antenna radiates a circularly polarized field, so the signal is distributed through all polarizations. This greatly reduces dropouts when performers or wireless devices move and their orientation cannot be controlled.
The HA-4540 has a 50 ohm BNC female right-angle RF connector and a dual mounting adapter that fits 5/8 inch 27 (US) and 3/8 inch 16 (European) stands.
The HA-4540 has a rear rejection (front-to-back ratio) of 14 dB, which helps it focus on signals in front of the antenna and reject interference from behind.
