Facets:
value: with vertical polarization
type: OTHER
Source sentences:
text: This makes it a good antenna at LF or MF frequencies, which propagate as ground waves with vertical polarization, but it also radiates enough power at higher elevation angles to be useful for sky wave ("skip") communication.
