Is there any potential Trio ER450 radio interference between Microwave antenna?
Typically there is NO concern of interference between a 450 MHz system and a microwave system, as microwave is above 3000 MHz. (3 GHz)
Such great frequency separation gives a lot of isolation for interference. I would still recommend the new dish be installed a 2 meter or
more away from the 450 MHz antenna, to minimize any minor interference concern. Also, if closer the metal of the dish might affect
the radiation pattern of the 450 MHz antenna.
What is the difference between isolated and non-isolated coaxial sockets? e.g. GUE7011W
A non-isolated coax socket is a standard socket. If you wish to install a socket to connect your TV coax lead into, this is what is required. Also, this version must be used for satellite installation as a two way signal is required. The satellite box does not only receive a signal, it also sends a signal back to the satellite dish. An isolated coax socket will block the return signal.
An isolated socket lets the signal through from the aerial/satellite dish but does not allow any kind of return signal/current. This type of socket would be used where a communal dish or aerial is installed, such as in an apartment block. The isolated socket blocks interference from receivers (televisions, digital boxes, satellite boxes) which spoils the signal which the rest of the users receive.
