DIAMOND - CMF2000 - LINE ISOLATOR / COMMON MODE CHOKE FILTER - EFFECTIVE FROM 1 TO 54 MHz - MAX. POWER 2 kW p.e.p.SSB

The CHOKE BALUN is a line isolator, that is a useful filter to limit or even eliminate the noise caused by nearby devices: televisions, radios, computers, etc.
It is also useful during the transmission periods to filter the return currents that flow on the external part of the coaxial cable.
The CHOKE BALUN can be placed under the antenna, regardless of the model, between the balun and the coaxial cable.
It can also be placed in a radio station, between antenna cable and transceiver, to improve isolation.
It can also be useful to break the "ground loops", placing one between the radio and any amplifier.

The "Common Mode" filter acts on the currents that travel on the external part of the coaxial cable sheath during the transmission periods, something against which the "Low-Pass" filters are ineffective.
The union of a line / choke isolator and a low-pass filter (for example our HSP 35/600) can be successful for eliminating TVI phenomena.
It can also be very useful in mobile installation to avoid annoying R.F. feedback from antennas with grounding problems.

WE RECOMMEND THE USE OF COAXIAL CABLES WITH DOUBLE SHIELDS TO MAXIMIZE RESULTS
