FM Antennas
Vertical Dipole Omnidirectional FM Broadcast Antenna
FM Antennas include dipoles, panels, yagi and logarithmic antennas for directional and omnidirectional patterns, ideal for any kind of coverage. Available polarizations are: Vertical, Horizontal, Circular.
DB provides both the antennas and all the elements of a complete antenna system: power dividers, coupling cables, mounting brackets.
We can also design the estimated coverage area for your antenna system thanks to our accurate software based on satellite maps.
MAIN CHARACTERISTICS:
-
General. The P1 Vertical Polarization Dipole Antenna series is designed for FM Broadcast Band (87,5 –108 MHz). Each antenna is composed of one balun feed vertical dipole and is made with stainless steel (PX1 models) or resistant aluminium alloy (P1 models).
-
Omni-Directional. The radiation pattern is omnidirectional (see horizontal pattern in the next page).
-
Antenna systems. By stacking more antennas it is possible to obtain customized patterns, to increase the gain and the power handling capacity according to user’s requirements. Custom patterns, electrical beam tilt and null fill designs are available upon request.
-
Broadband. Suitable for single channel or broadband operations with multi-channel combiners.
HIGHLIGHTS:
-
Easy installation. The standard mounting brackets are designed for instant installation on poles with diameters from 32 mm to 90 mm. Special brackets are available upon request.
-
Water, icing, moisture protection. The input connector is protected against rain and icing by a special housing. The internal balun is also protected against water, icing and moisture by a sealed housing.
-
State of the art mechanical design. By employing the finest materials (stainless steel, non-corrosive aluminium alloy, marine brass, virgin PTFE) it is assured a longer life service.
-
Lightning resistance is assured by the DC ground potential of the entire antenna.
