How is the receiving distance of car intercom shortened?

Shortening the receiving distance is related to two factors.

1, the force transmitted by the other party becomes smaller, so the corresponding distance to you is not as far as before. To solve the problem, it is necessary to check the other party's radio station, antenna and feeder, and it is best to check the output power and standing wave ratio of the antenna side.

2, the ability of your car platform to receive signals has become weak. Mainly check the receiving sensitivity of the machine, whether the antenna is matched, whether there is internal fracture, and whether there is internal fracture of the feeder.

Check the above two items, and you should be able to find the reason.
