Splitters and Combiners

GPS Two Port Power Divider
DPD-GPS
Optimise antenna performance
Run two GPS receivers from a single antenna
The Panorama DPD-GPS allows you to run two GPS Receivers from only a single antenna. The DPD-GPS splits the received signal
from the antenna to two receivers while only allowing one of the receivers to feed voltage to the antenna ensuring that the
antenna is able to function correctly.
The DPD-GPS is perfect for ensuring that multiple compatible GPS
receivers can be used in the same vehicle with the minimum number of
antennas thereby reducing clutter and installation cost.

VHF & UHF DIPLEXER
Use one antenna for two radios
The Panorama diplexers, can either combine the signals from two antennas
to a single multiband radio or split the signal from a duel band antenna to two
separate radios. There is no need for switching or matching as the DPX will
automatically split or combine UHF and VHF to route them to their separate radios
The compact unit requires no power cables and can easily be installed in the roof
lining of any vehicle or mounted next to the radio`
The DPX's ideal for all dual band and VHF/UHF migration system.
