Expandable horn systems from the specialists

Horn antenna systems are AFC's specialty. Antennas For Communications offers full design and manufacturing capabilities for Conical Horn Reflector Antenna Systems.
AFC's monolithic antenna design enables a level of horn precision that no metal horn can match. There are no seams on the reflector or radome to affect the radiation pattern, and no moisture intrusion, with AFC's proprietary molding process.
AFC is recognized as a world leader in the development of 7-, 8-, and 10-foot models offering performance which has long been the industry standard. Expandability and competitive price are additional benefits.
AFC offers its customers a complete line of waveguide, combining networks, couplers, hangers, and dehydrators. Our experienced erection team is capable of handling any installation, whether atop a skyscraper or on a mountainside.
Conical Horn

**Advantages**
The Critical Horn Advantages	The AFC Advantages
Multi-band operation Very low sidelobes Superb cross-polarization discrimination (XPD)	Experience works for you - Years as a telephone industry [-spec] horn supplier nationwide (and offshore). Ours is the standard. Choice of mounts - Platform or side-tower mounts available to meet your application needs. Color options - AFC white is standard, but your color can easily be matched. Single frequency or multiband - AFC networks enable you to combine up to three bands on one antenna; AFC couplers are available with single- or dual-polarized operation from 1.7 GHz to 17 GHz. Fully equipped horns - Every AFC antenna arrives complete with stabilizers, adjustment tools, lightning rods, safety rails, waveguide hangers, and all necessary hardware: you need not "shop" for critical parts of an AFC system.
