The following DIPLEXER separates the
following
bands:
- HF and 6m on one side (= 0 - 52 Mc).
- 2m and 70cm on the other side.
It allows the simultaneous operation of 2 different equipments (HF
and VHF/UHF) over one coax cable,
or the use of 2 antennas of the corresponding bands with one coax
cable.
That means, you can operate on HF and listen or transmit at the
same time on VHF or UHF,
all through the same coax cable.
It is also suitable to connect a 3
band antenna (uhf/vhf/6m) with
the
antenna connectors of a transceiver as IC-706, FT-100, or TS-2000
transceiver.
The following data was measured at 50
Ohm input and output:
- Attenuation of the other band is very high (over 60 db)
- Insertion loss is negligible (less than 0.2 db).
This technical description with
circuit diagram, construction guide, and adjustment
procedure for proper operation, together with a list of providers for the required components.
