WIRING
The ILER-20 wiring is very simple, as long as you remember that:
- For the antenna connection use a thin, RF-rated coaxial cable such as RG-174 or similar.
- If you install the tuning polyvaricon off the circuit board, you should use short and stiff wires, as the
mechanical stability is very important.
-A metal box is highly recommended.
The ILER-20 is not protected against reverse polarity!
It is a good idea is to place a diode (i.e. BY255 or larger) in parallel with the power supply input. The
cathode (the end of the diode with the printed band) goes to the positive wire. If your power supply has
short-circuit protection or has a fuse on its output, fine; otherwise, you will need to build or buy a cable
with an in-line fuse in series.
