Information on
installation and operation All filters in the
FilterMax IV are constructed with high quality components using
Micrometals toroid cores and low-dissipation, high Q TDK capacitors.
While these filters are rugged, you should be aware of problems that can
arise when operating the unit into a high SWR which can cause unexpected
high RF voltages, even at 200 watts. Also, the filters are designed for
50 ohms and a large departure from the design impedance can change the
filter response and you may not achieve optimal band to band rejection.
Be aware that the tuners built into many radios will not correct any
high SWR presented to the FilterMax IV. If you must operate into high
SWR loads you should use an external tuner connected between the
FilterMax IV and your antenna or antenna switch. Most amplifiers have a
reasonable match on the input and should not normally present any
problems. The FilterMax IV is packaged in a heavy
duty (0.090 wall) extruded aluminum case. Front and rear panels are
laser engraved so the lettering will not wear off with use. RF
connectors have teflon insulation and gold plated center pins. Power
requirements are 12-14 vdc at 150ma.
