Additional Antenna Options

If you live more than 20 miles from an FM transmitter of interest and you live in a wood frame building, consider placing or mounting an FM antenna in the top of the build- ing (attic or crawl space). Run additional coax lead-in wire to the radio. “Rabbit Ears” could be used for this purpose.

It is also possible to use an FM antenna designed for outdoor use in an attic or crawl space. The performance will not be as good as outdoor mounting but it will still be much better than lower down in the residence.

The best overall radio reception can be obtained from an FM antenna designed for outdoor use mounted on a roof- top. Some examples follow:

Winegard PR-6000 (length 33”, width 65”),

an directional antenna, good if all stations are in roughly the same direction.

Antennacraft FMSS (max width 54”),

an omnidirectional antenna, better if the stations of interest are located in widely different directions.

Am Antenna Options

The Wire Loop AM antenna included with the SoundWorks Radio 820HD is a precise match for the AM tuner. The only reliable way to boost AM signal strength is to place a tunable, sympathetic booster antenna next to the Wire Loop AM antenna. This type of booster antenna is passive. No wire connection is needed. The dial on the booster antenna should be adjusted for peak signal strength after tuning in an AM station.

Two models of this kind of antenna are:

Terk AM Advantage

C. Crane Select-A-Tenna Regular Model
