Did you read the documentation? What does it say?
$ grep -nr broadcastdelay ntp-4.2.4p0/html | cut -f-1
The broadcast and multicast modes require a special calibration to
determine the network delay between the local and remote servers.
Ordinarily, this is done automatically by the initial protocol exchanges
between the client and server. In some cases, the calibration procedure
may fail due to network or server access controls, for example. This
command specifies the default delay to be used under these
circumstances. Typically (for Ethernet), a number between 0.003 and
0.007 seconds is appropriate. The default when this command is not used
is 0.004 seconds.
Specify the default propagation delay from the broadcast/multicast
server to this client. This is necessary only if the delay cannot be
computed automatically by the protocol.
