Antenna connection set to extend receivers (T20/T60RX-03ADL) with an extra receiver. With this antenna cable, it isn't necessary to install a second antenna.
WARNING: The new receiver has to be mounted next to the existing receiver because the antenna cable is ca. 20 cm long.
In case the memory of the existing installation with one or multiple receivers is completely full, it's possible to add an extra receiver. This receiver can be connected by the green 1-on-1 parallel connector.
