Metrics Show article metrics. A simple vertical dipole or vertical co-linear antenna is very popular for this type of general transmission. The allocation of sub-bands enables the indicated category of users to employ any frequency within that sub-band provided that no appreciable energy falls outside that sub-band. Contest sections. See a band's article for specifics. If nothing is received after the request, a new request is transmitted.
