Hi,
We are having a bit of a strange issue, we have have a site with 200’ tower that has a large wave guide going up to a high gain boradcast omni. This site was once used by another carrier who operated an MMDS system. We are doing some testing and when we connect an RB711-2Hn to the wave guide we are able to get a remote unit online however the signals are very different. We can hear the CPE at -54, yet the CPE can only hear us at -80. We thought it might have been a bad board or connector so we had an RB411AH + UBNT XR2 card, same exact issue, signals slightly different due to output power difference on the XR2 but ratio still way off.
We then popped a UBNT Bullet M2 on and magically our signal RX at the CPE that was -80 before was not -54. The CPE was an RB711-2Hn in all cases with a 14dbi ITElite panel antenna.
Any one have any ideas on what could be going on here?
We have tried swapping the MMCX to N jumper as well as the N to N jumper between the MMCX and the wave guide. So everything I can think of has been swapped even RB711 to RB411 and different RF cards.
Thanks
Tom
