The ADB Spearhead, CP Panel Antenna, has a proven track record of performance. It includes more than twenty years as a leading high power, multi-channel FM Circular Polarisation panel antenna.
Moreover, heavy-duty hot-dipped galvanised steel forms provide the screen and dipole assemblies. This also assures a long and trouble-free service under the toughest environmental conditions.
The Spearhead Panel also includes large crossed dipole radiating elements. The product focus is on high power multi-channel FM markets. It is ideal for multi-channel operation over the full FM band of 87.5 to 108 MHz. Each operating channel will achieve a VSWR of 1.1:1
The antenna design provides an excellent omnidirectional radiation pattern using three panels per tier around a triangular tower. The Spearhead panel provides a 6dB beam-width of 120 deg. A combination of unequal power division and appropriate phasing between faces provides for a wide range of directional patterns. The AlanDick Broadcast design engineers will be on hand to assist you with your coverage plans. Customisation of the antenna for your project is available.
A feature of the Spearhead screen design is the additional strength that allows tower crews to climb on them. Minimising the aerodynamic areas is also consistent with the round cross-section members of the galvanised screen and dipole assembly.
Spearhead CP Panel Antenna customisation is available
Moreover, GRP covers provide weather protection to the dipole feeds. This greatly increases reliability while reducing operating costs. With a fully pressurised feed system and careful attention to dissimilar metal junctions, the Spearhead arrays provide an integrated design. This provides reliability that is second to none.
