EUCAST Co. Ltd. All rights Reserved antenna. GPS antennas should be spaced at least 1m to prevent interference between the two Because the GPS antenna receives +5V DC from the receiver inside the ECL4248-2401, the connection point between the GPS antenna and the feeder cable must be waterproof.

(The GPS antenna connector has to be waterproofed using Insulation tube.) If a cable short circuit occurs, damage to the power supply of the equipment. Because GPS is a device that receives very low level signals, it needs to be separated from the surrounding radio sources (another communication equipment, RF antennas, etc.). Installing the GPS antenna closely to the ground terminal of the building or the external conductor, the signal power is attenuated. so, install it as far as possible. The GPS antenna must always be level. 3.3.2 Installation GPS cable The GPS feeder is selected that the loss is less than 30dB at 1575.42MHz. The loss value of the cable is different depending on the Cable Type and Using Cable length. The cable must be selected and used according to the installation environment.
