FILTERS & JOINT BOX
These filters have been designed to help eliminate signals outside the specified
group of the filter. Example: The group B filter will reduce group C- D, group A
and VHF signals.
They are useful when a strong out of band signal is present and needs to be reduced
to prevent overload, or to prevent reception of unwanted signals from distant transmitters
out of region. The Group Pass Filters and Joint Box have THRU DC power and although
they can be used between the aerial and amplifier it is preferable to use them after
** For UK & Eire; a suitable 4G filter may be required.
