ANTENNA NVIS, for mobile Codan 3040 tuner

Definition

NEAR VERTICAL INCIDENCE SKYWAVE (NVIS) KIT
The NVIS kit is an add-on accessory for Codan's 3040 Antenna.

Short vertical whip antennas are poor radiators at high take-off angles. This makes short distance communications difficult,especially in hilly terrain. Making the whip longer and more horizontal improves the high take-off angle radiation efficiency.

Improves short-range communications
Transmit and receive paths over the range of 0 to 500 km will be greatly improved with the addition of the NVIS kit.

Easily attached to a variety of vehicles
The NVIS kit can be quickly and easily attached to a wide variety of vehicles. All fitting instructions are provided – no special tools are required.

Robust design
The robust design of NVIS has been proven by numerous field tests.

Note: The frequency range of the NVIS kit is 1.6 to 12 MHz.
