The frequency in MHz and the modulation used for a particular BroadcastService.

Property	Expected Type	Description
Properties from BroadcastFrequencySpecification
`broadcastFrequencyValue`	Number or QuantitativeValue	The frequency in MHz for a particular broadcast.
`broadcastSignalModulation`	QualitativeValue or Text	The modulation (e.g. FM, AM, etc) used by a particular broadcast service.
`broadcastSubChannel`	Text	The subchannel used for the broadcast.
Properties from Thing
`additionalType`	Text or URL	An additional type for the item, typically used for adding more specific types from external vocabularies in microdata syntax. This is a relationship between something and a class that the thing is in. Typically the value is a URI-identified RDF class, and in this case corresponds to the use of rdf:type in RDF. Text values can be used sparingly, for cases where useful information can be added without their being an appropriate schema to reference. In the case of text values, the class label should follow the schema.org style guide.
`alternateName`	Text	An alias for the item.
`description`	Text or TextObject	A description of the item.
`disambiguatingDescription`	Text	A sub property of description. A short description of the item used to disambiguate from other, similar items. Information from other properties (in particular, name) may be necessary for the description to be useful for disambiguation.
`identifier`	PropertyValue or Text or URL	The identifier property represents any kind of identifier for any kind of Thing, such as ISBNs, GTIN codes, UUIDs etc. Schema.org provides dedicated properties for representing many of these, either as textual strings or as URL (URI) links. See background notes for more details.
`image`	ImageObject or URL	An image of the item. This can be a URL or a fully described ImageObject.
`mainEntityOfPage`	CreativeWork or URL	Indicates a page (or other CreativeWork) for which this thing is the main entity being described. See background notes for details. Inverse property: mainEntity
`name`	Text	The name of the item.
`potentialAction`	Action	Indicates a potential Action, which describes an idealized action in which this thing would play an 'object' role.
`sameAs`	URL	URL of a reference Web page that unambiguously indicates the item's identity. E.g. the URL of the item's Wikipedia page, Wikidata entry, or official website.
`subjectOf`	CreativeWork or Event	A CreativeWork or Event about this Thing. Inverse property: about
`url`	URL	URL of the item.

Instances of BroadcastFrequencySpecification may appear as a value for the following properties

Property	On Types	Description
broadcastFrequency	BroadcastChannel or BroadcastService	The frequency used for over-the-air broadcasts. Numeric values or simple ranges, e.g. 87-99. In addition a shortcut idiom is supported for frequencies of AM and FM radio channels, e.g. "87 FM".
