01 When it is needed

When a team usually needs a repeater.

Obor Kuasa designs, supplies, installs and supports walkie talkie repeater systems for teams in Malaysia.

01

Floors, basements, blocks

Calls break up between floors, basements, car parks or separate blocks.

02

Large sites

Users on a large site (plant, campus, quarry, plantation, venue) are out of handheld-to-handheld range.

Shared channel plan

Several teams share one channel plan and need a dependable common path.

02 Follow the signal

From a dropped call to a shared talk path.

  1. 01 / Problem

    Calls break up

    Handheld radios cannot reach each other across a site, building or route.

  2. 02 / Repeater

    The talk path goes up

    A repeater, with its antenna placed for the coverage area, receives and re-transmits the call.

  3. 03 / Coverage

    Teams share one path

    Several teams share one channel plan and a dependable common path. Not every site needs this — a survey tells you.

03 What we design and deliver

One system, from repeater to antenna.

What we look at before proposing a system: the repeater and frequency plan, the RF path, power and protection, indoor coverage and monitoring.

04 Coverage topology

How the blocks connect.

Select a block to see what we check. Light pulses trace the talk path from handhelds through the antenna to the repeater.

  8. Alarms and who responds.

05 How it works

Survey. Design. Install. Support.

Every proposal starts from where people need to talk, not from a product list.

Drag the handle. Left: handheld-to-handheld only, with typical problem areas. Right: the same site with a repeater on high ground.

Licensing

MCMC frequency planning

Radio frequencies in Malaysia are regulated by MCMC. We check the licensing requirements for your frequency plan as part of the design.

Do you need one?

Not every site needs a repeater

If handhelds already reach each other where people work, a repeater adds cost without benefit. A site survey tells you which case you are in.

09 Field questions

Repeater questions.

Short answers. The final design still depends on what the site survey finds.

01Do I always need a repeater?

No. If handhelds already reach each other where people work, a repeater adds cost without benefit. A site survey tells you which case you are in.

02Can a repeater work with the radios we already have?

It depends on the band, the mode (analog/DMR) and the radio models. We check this during the survey.

03Where do you work?

We are based in Bandar Sri Damansara, Kuala Lumpur, and serve teams in Malaysia.
