This elevated feed antenna delivers a remarkable 4 dB improvement, even when mounted on roof racks or gutters. It is pre-tuned to the specified band, offering quality construction and adaptability for diverse mounting options.

Product Features:

• This antenna is suitable for mounting on vehicle roof racks and gutters, elevating the 1/4 wave antenna above lights and sirens.
• Whip is replaceable hence the antenna can be easily transformed into a high gain antenna in seconds by replacing the whip section.
• This is a durable antenna with handcrafted choke assembly from solid brass, chrome-plated for durability in challenging conditions.
• This antenna has pre-tuned bands for convenient, ready-to-use communication solutions.

Application Areas:

• CD91-70-70 is ideal for Emergency Service Vehicles, specifically designed for emergency service vehicles, ensuring optimal performance in critical situations.
• This antenna can also be used at static or fixed locations. We recommend using RF surge arrestors like Polyphaser GT-NFF-AL with this antenna when using at fixed location.

In The Box:

• 1x RFI CD91-70-70 UHF antenna without any cable and connector

Note:

• Mopole antennas such as the CD91 exhibit a 4 dB improvement in performance over a 3-wave whip but in pattern tests deliver only 2.0 to 2.5 dB of actual gain.
• This improvement in performance can be attributed to a lower angle of radiation and is of particular benefit to users in rugged terrain conditions and in heavily built-up city areas.
• Available pre-terminated with 5M RG58 cable. Use -73 to replace -70 suffix.
