All radar altimeters have three basic components, an antenna, a receiver transmitter, and an indicator.

Antenna
The antenna can come in different types depending on where you decide to mount it on a flat or skewed area under the fuselage. Antennas are designed specifically for each system, so changing the unit also involves changing the antenna.

Receiver Transmitter
The core of the device, a radar altimeter actually is a single frequency radar system that broadcasts a pulsed tone directly downward. The time it takes for the reflected tone to be received directly translates into your height above the terrain. Clearly, the better the Receiver Transmitter, the more accurate your readings will be.

Indicators
All models allow you to select a decision height (DH) altitude or any other altitude to about 2,500 feet above the ground. When you descend to this preset altitude a visual and aural warning will sound. Some models use electronic digital displays and others use the more common analog (dial) displays. The indicator you choose depends on whether you have the required panel space for a 3 inch analog type or if you prefer a smaller size. A few indicators and units offer some additional features and are all digital models.

At APG-Eastern Avionics, we have a full selection of radar altimeters for a wide variety of aircraft. Call us -- we can help you select your perfect system.
