Voltage sampling unit
These units are designed to provide an RF sample voltage proportional to the RF voltage connected to the input bowl feed-thru assembly on the unit. These units will allow AM broadcast stations to conduct Method of Moments proofs of performance on arrays with tower heights and geometries in which base toroidal current transformer samples are not permitted. The units are designed as an inductive voltage divider. This provides static (dc) path to ground, eliminating a separate static drain choke. The input impedance of the unit is high within its specified frequency range. This high input impedance minimizes any tower impedance "shunting" and current phase shift. Units are designed for indoor mounting or can be mounted outdoors with an optional weatherproof cabinet assembly.
