I don't have the OB9-5 but do have an OB7-3, which is two element on 15 and 20
and 3 on ten. I've modeled it and see about 10 to 11 dB F/B (freespace) on 15
and 20 and about 20 dB F/B on 10. I would expect about the same for the OB9-5.

Hi, has anyone tried to verify the F/B (dB) of 18 - 25 , on the OB9-5? It seems
high to me with a 16.73 ft boom and literally 2 elements on most bands.
