Topband: Beverages over Radials

[Clive GM3POI]

I'm not sure whether this subject has been aired before, but given that a
Beverage needs ideally to run over lossy ground. Is it the collective wisdom
that a Beverage running for a large percentage of it's length over a radial
field won't work as well. That is for the moment Ignoring  coupling to the
Tx antenna. Has anyone proved this to be the case. 73 Clive GM3POI
