    YUP! i picked stations (VHF TV RADIO) from Chile (1000km or more ) by refraction that way with the helical monster...and some other antennas...with lots of FADING and it doesn't last long...

    HEIGHT above GROUND is of utmost importance beyond 200kms...

    PS: it will be useful to know the POLARIZATION on the TX...

    nice...I did some 400km 500km dx back in the 90's ...but i have a cement glass fiber roof W (dielectric until rain) over which i put 2 x 30 mts helical wire , feed at the middle with 300 ohms cable over or close to 15 dbi i guess...to mi advantage the roof was aligned with the big cities...

    stations piled up and kick each other out...(yamaha fm receiver good selectivity and sensitivity)

    He's VERY limited in Theory and Software...

    It seems like he's always GUESSING  with some things he REALLY know (from experience) the guy is old school...see his EQUIPMENT...

    In the Comments , he's always being CORRECTED...

    I asked him SEVERAL times about the IONNICA...(avoided me always)

    Knowledge is HARD...you must be flexible and keep at it...there's ALWAYS something NEW

    not is NOT the best design for less than 15dbi....

    There's hundred or thousand designs for 15dbi or more (in this iste even) EASIER to MAKE

    With the 722 i use ONLY METAL antennas...dielectrics SUCK the juice of the signals...

    PS:The BIG change in VSWR is not a real life issue...is a SOFTWARE setting , intersections, port, or other...(can't change THAT much for 0.01 or 0.02)
