We have a partnership with Poynting, and they are experts at antennas, so they will definitely be able to help you out!
As for directional or omni-directional antenna choice, if the antenna will be stationary in a rural area, it would make more sense to go with a directional antenna. However, if the setup will not be stationary, omni-directional antenna may be a better option.
