Model CD-135-470 135 - 470 MHz 2 dBi. Gain 


Design Features: CD-135-470 multi band coaxial dipole antenna is rugged all weather model, enclosed in a ABS radome, uses high class aluminum alloy and does not require any field tuning or adjustments. The compact size of omni-directional coaxial dipole antenna allows easy handling, shipping and highly suitable for receiving, transmitting, scanning, monitoring and jamming applications without having the requirement of multiple antennas. Antenna termination and feed cable lie enclosed inside the mounting pipe for complete weather protection.

Constructions: The multi band coaxial dipole antenna is consisting of large diameter radiating elements stacked vertically and enclosed in ABS radome. The special choke and spark gap technique is used for smooth VSWR and constant 2dBi. gain over the entire 135-470 MHz. frequency band. The UV resistant ABS enclosure has excellent transparency for RF signals and enough strength to withstand specified wind loads. The stainless steel mounting hardware is supplied with the antenna. The mounting hardware is suitable to mount the antenna on 25 mm to 51 mm outer diameter vertical pipe.
