General Information
• The WA-AS4 antenna splitter is a 4-way wideband antenna
splitter operating in the frequency range of 470 to 1,810 MHz.
• For the diversity operation the WA-AS4 is provided with two
identical antenna paths.
• For each antenna path there are four outputs available for the
connection of receivers.
• The operation is possible with antennas that are directly or
remotely connected.
• Each antenna input provides a supply voltage for active antennas
or antenna amplifiers. A maximum current output of 150 mA at
a voltage of 8 V DC is available for each input.
• The white LEDs "Ok" on the front side (
,
) show that the
antenna power supply is working. The red LEDs "Ovl" (
,
)
indicate that the maximum current consumption of an antenna
cable (e. g. due to a short circuit) has been exceeded. In such a
case, the antenna supply voltage is switched off automatically.
• The WA-AS4 provides two DC outputs. These outputs are
designed to drive one TG 500SR each. This eliminates the need
for space-consuming external AC/DC power adapters in mixed
setups of TG 500SR and TG 500DR. The WA-AS4 itself has an in-
ternal switching power supply.
• The dimensions and design are adapted to the TG 500DR and TG
500SR receivers, to create an optimal interplay with the TG 500
system.
