The need for clear and strong transmissions is important for constant communication in the field. Whether a first responder, electrician, or construction worker, a misheard word or sentence can lead someone to the wrong home or substation.
The Necessity of Antenna Strength
Thus, a powerful antenna is absolutely necessary in any type of geography or climate. Not only does it allow for extra bandwidth but also expands the signal coverage. And this means quicker response times.
Increasing an Antenna’s Power
However, there are some environments where the juice is not available to ramp up the signal strength. In these situations, you need to look into directional couplers. These devices provide the ability to link two devices or power sources together. They can either draw power from each other or one can increase the strength of the other.
To get an idea of which directional couplers are right for you, here are three types to consider.
This model contains a main line hookup and a coupled line. The manual switch enables you to redirect power if needed should one antenna need more power.
Both ends of the device setup the use of coupled ports. Thus, power to the destination equipment is immediately doubled. Before using this coupler, the user should make sure all loads are well-matched at the 50 Ohm level.
4-Port Dual directional
Similar to the bi-directional unit, dual directional couplers do not require exactly matched loads on all ports. Therefore, equipment or power sources with differing Ohms can be hooked into the device.
Choosing the Right Coupler
Select the right directional couplers by reviewing the items or power supplies you need to combine. Next, ask the right questions at locations such as Werlatone. These companies have Subject Matter Experts (SMEs) who have advanced knowledge of these items.
In the end, you may need to experiment with a few couplers to see if they do the job for your power needs.
