The WiNRADiO WR-DNC-3500 Frequency Down converter is
especially suitable for use with WiNRADiO G3 series VHF/UHF receivers,
such as the WR-G305i and WR-G305e receivers.
Unlike most low-cost down converters, the WiNRADiO WR-DNC-3500 down
converter features a high-stability 0.5ppm reference oscillator, to
ensure excellent frequency stability at the output. |

Installation
|
The down converter is connected to the antenna and the receiver via an
SMA connector and a suitable low-loss coaxial cable. In this
installation option the power is applied directly to the down converter.
We recommend using a well-filtered power, preferably that of a linear
power supply, such as WiNRADiO WR-LPS-12200.
|
|
Alternatively, the down converter can be placed closer to the antenna
and powered via the coaxial cable. On the receiver side, the power can
be injected via WiNRADiO
WR-BT-1201
"Bias T" device. This would be a preferred option to minimize losses in
the cable if the antenna is located at a greater distance from the
receiver.

This is a separate item
which the user can install himself. It can be also used with other
third-party products (not necessarily WiNRADiO receivers), to extend
their frequency range up to 3.5 GHz:
The DNC-3500 is a simple down-converter
with no receiver control; it is placed between the antenna and any receiver
antenna input. If used with the G305 or G315 receiver, set the top bar
option “Set Display Offset” to 1700 MHz for direct readout of the received
frequency. For any other receiver, the received frequency must be calculated
by adding 1700 MHz to your receiver’s dial display.
