![]() ![]() All equipment, regardless of whether it has internal or external antennas, is subject to the same maximum limits. In Norway, the transmitting power of wireless equipment is strictly regulated by law. No differences in transmission power on internal and external antennas Internal antennas, on the other hand, have slightly lower aerial gain but deliver signals more efficiently over a larger area. This, however, assumes that you are only looking at points within the antenna’s doughnut-shaped coverage field, pointing in the same direction as the antenna. External antennas have the best aerial gainĪntenna gain is the ratio of an antenna’s effectiveness, the direction in which it transmits, and the effectiveness of an imaginary antenna with no signal loss.ĭue to the fact that antenna gain is an indicator that combines efficiency and directionality, external antennas produce the best results. External antennasĬonnectors on the circuit board may occasionally become loose due to rough handling, resulting in an unreliable connection and diminished effects. Interference will also be introduced where wires cross over electronic components. Because the antennas are basically external, they must also be connected via cable, and the connection points and cable contribute to the difference’s efficiency loss. ![]()
