More Specialist Iridium Antennas

The following Iridium antennas are also available upon request.

Active Iridium Antenna

Designed for harsh environments, the AD520-10 consists of two RHCP dipole antennae housed within 4mm thick GRP radomes mounted on a common base. One antenna is for signal transmission and one for reception.

Note: This is an expensive, specialist antenna, needed only for very long cable runs.

Iridium Car antenna

(with 5 feet cable)

Iridium mobile (car) magnetic mount antenna

Magnetic mount, pocket-sized antenna travels with you from car to car, providing improved reception. Must have large metallic surface to mount antenna (40 inches square).

Note: this is the same small antenna as supplied in the box as standard with the Iridium portable phones.

Larger Iridium Car Antenna

(with 5 meter cable)

Iridium mobile magnetic mount antenna

Larger magnetic mount antenna performs much better than the smaller "car" magmount antenna. This antenna works very well for delivery skippers, and other situations where better reception is required, but a permanent installation is difficult.
