  1. MikroTik MTAO-LTE-5D-SQ mANT LTE Omni

    jonirak replied to Admin's topic in HF, VHF and UHF

    I know it's old post but could I have the dimensions in a sketch file? I'd like to copy it using a double side pcb like the original. What other designs would you suggest for 4G 1800MHz to build easily using pcb, copper wire or sheet metal? I have build this for 1800MHz and it's decent but I'm looking for a better one.

    What about the 75 Ohm cables+connector? I don't know about antennas so I don't know if I can use 75Ohm with the Huawei modem. Can I use any type (50/75) with any modem?

  3. 1800MHz Patch Antenna

    jonirak replied to Admin's topic in Modeling antennas

    I wan to build an antenna 1800MHz for a Huawei E5372. I have ordered TS-9 to F female connectors. Is it possible to use 75 Ohm cable+connector to use them on my modem or it supports only 50 Ohm? I would prefer a disk yagi because it's much easier to build with galvanized sheet. Should I isolate the driven element? Are these dimensions correct?
