(click thumbnail)Slant-VPropagation Systems Inc. is displaying various FM antennas, including medium- and high-power versions of both the Power-Tiller and Slant-V, along with a cavity-backed panel antenna and its vertically polarized PSIFLV.
The Power-Tiller is an omni-directional, circularly polarized FM broadcast antenna with copper and corrosion- resistant brass construction for good conductivity and longevity, as well as VSWR bandwidth.
The high-power PSIFHR supports input powers up to 60 kW; the medium-power PSIFMR is for input powers up to 15 kW.
The elements are stacked in arrays of up to 12 bays for increased gain, and are end-fed from a support boom. For arrays requiring beam tilt and/or null fill, a center feed system is required. The entire antenna system, including the feed, is pressurized.
Each antenna is supplied with standard galvanized mounting brackets for round leg mounting on uniform cross section towers. Custom mounting brackets also are available. Fiberglass radomes are available for antennas exposed to adverse weather conditions.
The Slant-V antenna consists of two shunt-fed dipole elements in a slanted V configuration forming a circularly polarized radiator. It also is available with vertically or horizontally polarized elements.
The Slant-V is available with “breakdown” elements to allow the dipole elements to be disassembled from the support boom. PSI says this reduces crating and shipping costs. The Slant-V is available in low-, medium- and high-power. Models include: PSIFML for input power up to 4.5 kW; PSIFM for input power up to 12 kW; and PSIFH for input power up to 40 kW.
