< Optibeam's OB4-40, which I have (sold the M2) has both proper 
distance to the loading element (in their case a coil) as well as a stub. It 
shows no impact on 15 or at least small enough that I've not been able to 
measure a degradation on the FB on 15.

I'd say you'd have a 100% chance SOMETHING is going to be impacted on a 5 
band hex beam. The amount will vary.... for most they happily move along 
knowing they have the antennas...

## Ok, so where does the Optibeam OB4-40 resonate ?   It has to
resonate somewhere.  The f12 N series resonates around 24 mhz...
and of course will screw up a 12m yagi.
