Can someone do an educated comparison between these two antennas?
A study at http://www.gordon.army.mil/ac/Winter...02/USMCnet.htm
seems like an ad, instead of a fair comparison.
Hi Tony,
It is a fair comparison using a well known modeler. They cite EZNEC
which is our "gold standard" here for modeling. True, this is an
amateur group, but there are a lot of professionals here, many with
military experience, obtained directly or through contracts. None
would shy from recommending EZNEC for professional work.
Performance-wise the two are a wash. One dB accuracy is exceedingly
difficult to achieve in the field, and all the variables of
installation, terrain, use, what-have-you could easily erase slim
advantages. Of all things to be considered is height and visibility
and even here, both seem to be equivalent. Matching is examined and
taken care of suitably for each's design - again equivalent.
The only difference appears to be that the OE-254 appears to suffer
some loss. How and where, the authors don't seem to be either aware
of it, or go into any explanation. Still, even with this the OE-254
seems to be a performer.
Choose the one with the fewest parts (or simplest design).
