Jabarkan Reka bentuk sistem dari Pengulang radio dalam bahasa melayu

Pengulang radio biasanya terletak di tempat-tempat yang memaksimumkan keberkesanannya untuk tujuan tersendiri:

Pengulang "aras rendah" repeaters are used for local communications, and are placed at low altitude to reduce interference with other users of the same radio frequencies. Low-level systems are used for areas as large as an entire city, or as small as a single building.

"High-level" repeaters are placed on tall towers or mountaintops to maximize their area of coverage. With these systems, users with low-powered radios (such as hand-held "walkie-talkies") can communicate with each other over many miles.
