Portable Rubber Antenna 3G 4G Enhanced Version Antennas

The design of each model is different. The handheld type has both built-in antenna and external antenna. The advantage of the built-in is that it is compact and portable; the advantage of the external antenna is that the gain can be greater, the sensitivity can be better, and the directivity can be better. The result is a longer reading and writing distance. The fixed readers are generally not built-in, because the built-in antenna read-write distance and sensitivity are not particularly in place.
