Question about 11GHz 2.6ft dish on PTP820?

We get this question raised from one customer asking about why there is no 2.6ft antenna option on 11 GHz on PTP820 direct mount antenna?

here is what i like to share:

1. For all bands, we use 1, 2, 3, 4 and 6ft dish for PTP820 direct mount antennas, which is aligned with most antenna manufactures offer on dish size.

2. on 11 Ghz, we decided not offer 2.6ft dish and replaced with 3ft dish. the 3ft dish offers better antenna pattern and better antenna gain. In addition, we make the 3ft dish more cost competitive than the 2.6ft currently offered in PTP800 line.

Following is the antenna pattern
