Hi,

I'm using CBX daughter board which supports from 1.2GHz to 6.0GHz with
ANT500 (from 75MHz to 1GHz).

Actually, I didn't know this antenna coverage.

I have two question.

i) Is there any problem when I use ANT500 with CBX ?
I have tested QAM and QPSK performance using OFDM using those devices and
the results are poor(very unstable, too many bit error in very short range).
So, I doubt this is antenna compatibility with CBX.

ii) Which antenna is best for CBX 40MHz(1.2GHz-6.0GHz) and USRP N210 ?
There are three products:
1) VERT400 (144MHz, 400MHz, 1200MHz Triband)
2) VERT900 (824-960MHz, 1710-1990MHz Dualband)
3) VERT2450 (2.4-2.5 and 4.9-5.9GHz Dualband)

Thanks.
