FG4490 HOPF GNSS time server Antennas
$0.00
The antenna is placed in a round and waterproof plastic housing. The body cover is arched, to prevent any rainwater, snow or other impurities penetrating inside the antenna. The mechanical structure is made of solid, anodized, and cast aluminum. It is designed to withstand strong winds. In addition, special thermal elements are used inside it, for automatic melting of ice and snow. The active antenna gets its amplification power through the coaxial cable and the time server itself. It has the ability to amplify weak signals, and remove unwanted noise. It is one of the best antennas for time servers in the world.

Mechanical structure of the antenna
The antenna is housed in a round weatherproof plastic casing. The casing cover is arched to prevent any rain water, snow or other impurities from settling on the antenna.
The mechanical construction consists of sturdy, anodized aluminum or aluminum die-casting and is designed to resist high winds.
The plastic housing can be installed horizontally as well as vertically to the mechanical parts, allowing both wall and flat-roof installation of the antenna. The antenna cable can be fed either through the base or through a slot on the side of the mounting flange.
Electrical structure of the antenna
As the antenna is non-directional, reception cannot be improved by mechanical shaping as, for example, with parabolic antennas. Therefore the signal strength at the antenna input is about 1 x 10-16 Watts and already below the generally permitted noise level.
An extremely low-noise pre-amplifier is placed behind the antenna in order to feed the signals to the electronics via an antenna cable. The antenna cable also supplies the voltage to the pre-amplifier.
