  1. Hello,
    Thanks for posting this info! I purchased a used Verizon Wireless jetpack MHS291LVZ (made by Pantech) and have been trying to figure out the correct antenna adapter spec. I measured the outer diameter of the (two) antenna connectors on the jetpack and found this to be exactly 2.5mm! That would seem to indicate the connectors are neither IP-9 (2mm), nor CRC9 (3mm), nor TS-9 (3.5mm). Is there still another type of connector which has a 2.5mm spec??? Any insight appreciated. Thank you!

  2. I had some wireless cards that used MC connectors, not sure if that is what you needed
