Our customer is using Cisco 4G-LTE-ANTM-D= antennas (they've got several included with Cisco routers). They have ordered new additional batch, but the issue is that despite same part number they are different from "old" ones - it seems that manufacturer is different. Main issue is that on original (ie "old") antennas the joint is firm (ie antenna is not "loose"), while on new ones antenna is very loose in joint and moves considerably at slightest touch.
The manufacturing standard on "new" batch is quite bad, compared to "old" one - the "gap" in plastic assembling is noticeable, while on old ones it is almost invisible. Also font for part number print on antenna itself is slightly different.
Is there any way to resolve the issue? I think "joints" in "new" batch are faulty ... Suggestions (TY in advance)?
