Usage of the Antenna

When listening to short wave & FM Radio & WB weather bands, pull out the antenna and adjust the length or direction to find the best-receiving position.

Tip: if strong radio interference causes crosstalk, you can shorten the telescopic antenna.

Listen to the MW medium wave broadcast. The radio uses a built-in magnetic antenna to receive the medium wave. The magnetic antenna has a certain directive when receiving the signal. Therefore, when listening to the medium wave, rotate the direction of the radio body appropriately to find the best listening effect position.

External Antenna
When the indoor signal is poor, connect an external antenna can help improve the FM/SW reception. 9.84 feet long, it’s portable and flexible, very easy to install.

Put the spring coil of the external antenna outdoors or hang outside the window. Make sure the spring coil is perpendicular to the horizontal plane.
Extend the antenna cord.
Finally, clamp the alligator clip of the external antenna to the head of the radio’s built-in antenna.

NOTE: DO NOT use the external antenna during thunderstorms.
