How to connect antenna power supply?
For each active antenna there is included an antenna power supply with a branching filter (separator). It is used to remotely supply DC power to the preamplifier, permanently built into these antennas. The power is supplied via a coaxial cable, leading the signal from the antenna to the TV set.
From the side of the antenna the cable is connected with "F" compression connector or the so-called "quick F".On the other side we put the cable into the antenna plug attached to the power supply, which is also the voltage separator (branching filter). This is a very practical solution and a seemingly simple action. However, judging by the numerous inquiries on the subject, it can cause some difficulties. Especially with regard to proper seating of the coaxial cable in the plug (separator).
It turns out that an improperly wired cable can lead to a short circuit of the power supply. This happens when loose hairs from the braid touch the inner conductor of the cable. On the other hand, if too short a section of the wire has been exposed, then there is a lack of contact between the inner conductor of the cable and the corresponding socket in the plug.
So how to properly connect antenna feeder with the branching filter?
It is usually easier to show something than to describe it. The instructional video presented below shows how to connect the antenna feeder with ZZA-7 branching filter to the antenna cable. ZZA-7 is connected to all TELKOM-TELMOR active antennas. Enjoy watching!
