Andy,

The hygain monoband beams were available with 3, 4 or 5 elements.

203-BA, 204-BA, 205-BA  (20m)
153-BA, 154-BA, 155-BA  (15m)
103-BA, 104-BA, 1-5-BA  (10m)

One key to identifying them is the impedance match at the feedpoint.
The hygain beams all used a "hairpin match" which really looks something
like two gama matches connected in parallel.  To my knowledge, hygain
was the only manufacturer to ever use this method.

Hygain also used compression clamps on the telescoping elements.
These clamps are much more secure than a normal ring clamp.  They
actually put a "dent" into the point where the two pieces of the
telescoping elements are seated.  This makes it impossible to
disassemble the element without drilling out the compression point.
This was poor for a "portable" antenna but much more secure than
standard clamps.
None of the older manufacturers did this but I don't know about the
newer ones which have only been in business for the last 10 to 15 years.

Use these two data points to determine if the antennas are hygains or
not.

Now that I use a computer, I'm able to solve problems I never had
before!

Hi,
tut mir leid, aber das scheinen doch keine Hy-Gain beams zu sein, denn
sie
haben jeweils 4 Elemente!
Sorry!
