Band Pass Filter 4 meter 66-88 Mhz BPF4/3

25.00

BPF 4/3 Good used –we can tune if required -Image is for 2 cavity device -BNC connectors
Band-Pass Filter for the 80 MHz Band
DESCRIPTION
The BPF 4/3 is a 3-helical resonator band-pass filter with aperturecoupling
between the resonators.
This filter can be used as a preselector to protect a receiver against
interference from transmissions out of the pass-band, or it can be used
to reduce spurious output from a transmitter with up to 50 W of output
power.
The filter can be tuned within the entire 66 – 88 MHz band.
It has very small dimensions owing to the use of helical resonators.
Careful design and choice of materials ensure reliable operation over a
wide temperature range.
The housing is made of extruded aluminium, the chassis of steel, and
teflon insulation has been used in the coaxial cables and in the
connectors.
The filter is black vinyl coated to prevent corrosion.
