The STLP 9128 F from Schwarzbeck Mess – Elektronik is a Stacked Logarithmic-Periodic Broadband Antenna that operates from 70 MHz to 1.5 GHz. This linearly-polarized antenna provides an isotropic gain (far-field) of 9 dBi and has a VSWR of less than 2.3:1. It has an E-plane beamwidth from 60 to 75° and an H-plane beamwidth from 50 to 65°. The antenna is available in a housing that measures 1.95 x 2.26 x 2.54 m with N-type or 7/16 connector options and is ideal for generating defined field strength levels for radiated immunity testing.
