Horizontal or vertical near water?

    I take a KX3 to the ocean and to a fresh water pond. At the ocean I go vertical with a Buddipole but should I go horizontal at a pond? Does the pond give me any advantage over land based with the same setup?

    Not enough information to answer the question.

    Bands? Intended QSOs? Available height for horizontal? Desired pattern?

    Bogarting is bad practice.

    Fresh water does not offer the advantage that salt water does.
    But I think you already know that...
    Bring a fishing pole, nice bass in that pond.

    For years we camped at a Myrtle Beach campground on the ocean. Our campsite was about 400 yards off the ocean. Our camper backed up to a retention pond with sort of brackish water. I would take one of those 5' Radio Shack TV mast pipes and hammer it in the pond about 3' off shore (about as far as I could reach out without falling into the water). I mounted my screwdriver to this pipe. I ran the coax into the trailer and terminated it to my TS 570....It worked great and I worked 20 during the day and 40 during the evening... Oh yes, I also threw a coil of bare copper wire into the pond which became my ground...

    It worked and it was lots of fun...

    Pass on the bass, go for the trout without a doubt!

    No advantage to antennas (either polarization) over or adjacent to fresh water other than zero or little ground clutter. In fact, if I have my facts straight there might even be a tad less performance for horizontal antennas over fresh water (instead of ground that happens to have good conductivity) because there is less ground gain possible in that scenario.
    But saltwater is the best "ground" around and there is about a 6db advantage for low-angle stuff when using a vertical above it.

    Rule of thumb: Think of fresh water as lossy ground and saltwater as ideal ground.

    Brackish Water for all intent and purposes is Salt Water, not fresh.

    I wonder at what salt concentration in the water it becomes a 'good' ground plane...

    I heard Ponds can rejuvenate signals.

    Or something like that.

    Good question, but it's also a matter of the size of both the near and far-field saltwater surface area/ground plane, too. I think that would kind of make the salinity a moot point in the real world scheme of things. ( I once thought of installing a bunch of kiddie pools installed around my vertical and saturating them with lots of salt---but fthen ound out about the "far-field factor.":D)
