I'd like to try an external antenna, but one was not included with my

Thanks....

Hello Jim,

Every type of metalwirewill work for you situation (solid, stranded,
plasticized galvanized washing line, etc).

Most modern SW receivers with internal antennas are very sensitive,
but cannot handle strong signals, so longer will not always be
better.

To reduce the interference from electronic equipment close to your SW
receiver, you may put a coaxial cable between the actual antenna and
the receiver. You can use any type of 75, 90 or 50 Ohms cable. The
center conductor goes to the center pin of the mini plug and the bread
goes to the ground of the mini plug.

The antenna side of the cable needs some clarification. The antennawiregoes to the center conductor of the cable, the braid should be
connected to ground outside your house (or at least far away from
where you expect or have interference).

What is "ground"? *When you live in an apartment, it can be the metal
fence or railing of the balcony. *You can use a ground rod or any
other large metallic structure outside your house. Connect the braid
of the cable directly to the ground structure. Do not insert a long
run ofwirebetween the metal structure and the braid of the coaxial
cable.

For some form of static / impulse protection you may add a 1… 3 uH
inductor between the center conductor and the braid. Note that this
inductor will attenuate AM broadcast band reception.

As others said, you have to experiment with the orientation of thewireto get best signal/noise ratio. When you are very limited in
space for thewire, you may use some 5..10 feet of chicken mesh as
reception antenna or use more wires in a fan shape.

Best regards,

please remove abc when using PM.

OK, sorry, I see I was confusing the antenna and radio sides of the
coax. The radio side: center of coax to center of mini, shield brain
to surround of mini. Antenna side: braid to ground post, center to
antenna wire. So I can have the run between outside ground post and
radio using coax.

But can I damage G5 with an external wire? If so I'll use the whip
inductor. Please advise....

thanks
