to reduce spurious output from a transmitter with up to 50 W output

power.

design and choice of materials ensurereliable operation over a wide

temperature range.

The housing is made of extruded aluminium, the chassis of brass, and

teflon insulation has been used in the coaxial cables and in the

connectors.

The filter is black vinyl coated to prevent corrosion.
