Diamond CR8900 Quad Band Mobile Antenna


The CR8900A is returned to give the best bandwidth and VSWR over the FM portions of 10 m, 6 m, 2 m, and 70 cm ham bands when mounted on the side of the vehicle (i.e. trunk lid) using a K400 or K600 series mount.


With a gain of 2.15 dBi at 144 MHz and an impressive 5.5 dBi at 430 MHz, this antenna ensures optimal signal reception across multiple frequencies. Boasting a length of just 1.26 meters and weighing only 490 grams, the CR8900 is the perfect companion for those on the move. Its sleek design not only enhances portability but also adds a touch of sophistication to your communication setup.

Equipped with a power rating of up to 60 W, this antenna can handle demanding situations without compromising its outstanding performance. Don’t let impedance concerns hold you back – our CR8900 features an industry-standard impedance of 50 Ohms for seamless compatibility with various devices. Forget about complicated installations; connecting your device is as simple as ever thanks to the PL259 connector included with this antenna. Spend less time setting up and more time enjoying uninterrupted communication wherever your adventures take you.
