Model APT-4732 4400-5000 MHz 31.5dBi Gain 
 

TACTICAL RADIO RELAY ANTENNA

Design Features: The APT-4732 tactical microwave grid parabolic antenna uses 6063T6 ultra corrosion resistant architectural anodized aluminum alloy. It consists of full Parabolic reflector having a diameter of 1.3 Meter for use in all tactical and fixed station applications for conventional radio relay systems. The antenna covers full band IV, operates in linear polarization and requires only one operator for installation. The antenna features a rare combination of high gain, low side lobes and a rugged construction. APT-4732 is perfect for use in crowded electromagnetic spectrums which avoid interference from co-sited antenna. The mounting arrangement of Tactical Antenna permits to change the polarization from horizontal to vertical and vice-versa by mounting hardware fitted at rear end of the antenna.

Constructions: Radiating elements and the dipole feed are made high quality aluminum alloy to avoid any dissimilar materials. The rim and supporting arc are welded with argon welding technique to provide smooth finish and strong joints. The APT-4732 tactical microwave antenna operates in the 4400-5000MHz. frequency band and can be installed at vertical erected mast. The parabolic reflector is illuminated by a primary feed which is fitted to the center of assembly with quick fastener system. Radiating elements and the dipole feed are made of high quality brass. The grid parabolic antenna operates at D.C. ground with low resistance discharge path for protection against lightning and immunity to noise. All the screws, nuts and bolts of tactical microwave antenna are of stainless steel. The antenna supplied with army olive green color.
