permanent mount for Yagi antenna

I want to mount a Yagi antenna for a cell phone booster somewhat permanently on my 5th wheel. Has anyone come up with an easy inexpensive way to do this and still have the ability to point the antenna? Thanks.

    I had thought about something like that but I was afraid the yagi antenna and inside antenna would be too close together to work properly

    I would go with a pole mount on the ladder... Put it up and peak it .. Then return to ground.. take it down to move....

    Reasons
    One: you don't always need it
    Two: IT won't bother the OTA antenna
    Three As I recall those antennas need to be | not /

    I haven't seen any change in the performance of either antenna set. Monitoring the cell MIMO Yagi's signal levels, they don't change at all when the Sensar OTA antenna amplifier is powered up. The MIMO set does make a significant difference in cell signal levels when it's aimed at the nearest tower though. Often a better boost than our $600 cell amplifier/repeater.

    Time to learn something new, John...

    Polarisation diversity

    To take full advantage of MIMO, (currently used in 4G LTE communications), two antennas must be used.

    When installing directional antennas like a Yagi antenna, the first antenna must be rotated horizontally to a 45 degree angle and the second to a 135 degree angle. This is because of "polarisation diversity".

    LTE uses polarisation diversity to help distinguish between the two data streams sent from the tower.
