Topband: Non-resonant receive antennas

[James Wolf]

Not wanting to distract from this thread too much, but I'd like to ask a
question of the group.

If one had the opportunity to install two receiving antennas (such as loops
EWE's etc.) for Topband in either a series or parallel configuration, which
would be preferred.   Since Rick correctly stated that RDF doesn't account
for all variables, such as polarization, the same may be said for a pair of
antennas in the above configurations.  Two receive antennas in parallel will
narrow the lobe, but two in series will bring down the upper lobes.   

Can anyone comment on the advantage or disadvantage of either configuration
in real-world practice?

Thanks,
