How do I install it?
on PCB is written connectors
antennas input.
Top SMA UHF antenna (no offset, local frequency off)
Middle connector need connect to RTL SDR tuner dongle antenna input.
Bottom SMA connector need connect HF antenna.
switch to select the active antenna input.
The offset frequency HF band +100MHz,
for example: 3.5MHz = 103.5MHz
RTL SDR in software set frequency 103.5MHz etc.
UHF mode the signal passes through.
SMA A and SMA mini B connectors only +5V power supply.
