Horn Antenna Standard & High Gain / Coaxial SMA, Type-N Input

Standard / High Gain Horn Antenna - SMA & Type-N Inputs

ATM manufactures a high quality line of Standard Gain Horn Antenna, and High Gain Horn Antenna that are Linearly Polarized, lightweight and corrosion resistant.

Sometimes called Pyramidal Horn Antenna, microwave horns like ATM's horns are based on typical specifications for standard and high gain pyramidal horn antenna. The horn antenna models listed below are the most common gain values available, typically 10dB, 15dB, & 20dB gain horn antenna.

Other gain values and horn antenna sizes can be designed to your requirements. Please call us with your specifications to discuss your horn antenna requirements with one of our RF design engineers.

	Horn Antenna Tripod with Markings in Degrees - Click For Larger Image ATMs’ TP-3W Tripod is a great option for those who require a reliable way to mount our horn antennas. These durable and weather-proof tripods have a standard ¼-20 camera mount. They are made out of Eastern Hard Rock Maple, a hard light-weight vibration damping wood, which optimizes stability. The wooden construction will also decrease any reflections on side lobes, since wood will not reflect any incoming or outgoing waves. The bracket supplied with the horn to be mounted makes it simple to change the elevation angle of the horn, while the ¼-20 mounting screw makes it easy to change the azimuth angle of the horn. All available ATM microwave horns may be mounted using our tripod. Please note: Bracket Option ( /BR ) must be specified when ordering horn antenna for tripod mounting.
