• In regard to the sister blog entry about LoRa Gateway Antenna Upgrade:

    I'm surprised that the aerials are horizontal and the significant length difference between them and the wip.

    For regular 1/4 wave length ground plane antennas with standard impedance - 50R - the (four) aerials point about 45 degrees down and wip and aerials have about the same length. See M0UKD's 1/4 Wave Ground Plane Antenna Calculator.

    Do the supplier(s) of your upgrade antenna and the gateway mention:

    • Impedance?
    • Typical wave propagation pattern?
    • Low loss coax?
    • Placements of antenna and gateway?
