Topband: Titanex SES160 and SES80 Receiving Antennas

[Clay Curtiss W7CE]

Does anyone have experience with either the Titanex SES160 or SES80
receiving antenna?  Their web page doesn't have much detail on the specs
(http://www.titanex.de/frames/ses.html).  I'd like to know how much loss
they have.  They claim to have about the same loss as a beverage, but they
neglect to mention how long the reference beverage is.  Also, they claim a
F/B ratio of 25dB, but what I'd really like to know is the RDF.  If anyone
has NEC/EZNEC models or sufficient info to build a NEC/EZNEC model that
would be helpful.

Thanks,
