    Nope. None at all. The modelling already posted shows there's not even a single dB, so little difference you won't see any at all on a S meter or hear it with your ears. It would be a whole lot of effort and money for absolutely no difference at all.

    The only difference there could be is for local contacts if you were in a town but when you're on the top of a whacking great hill or a mountain an extra 10ft will make no difference at all.

    lol, 6 feet but on the water. I have my beams up pretty high but being on the ocean I dont think it matters, the dipoles and verticals all work fine at 20 feet. I plan on putting my old 3 element beam on a ten foot pole and see what happens, I am betting it does fine for DX . 73's

    I’m usually over inland salt water/ salt marshes...and the sort. It’s perfect.

    Hey homer,

    I operated MARS from USS Dwight D Eisenhower aircraft carrier.
    I made friends with the radiomen in the comm center.
    I had 5 acres of steel flight deck for a ground plane, floating in the middle of a salt water puddle somewhere on other side of the world.
    Sateside MARS operators were giving 30 to 40 over S9 RS reports.
    I don't know how much output power we were running but the RM guys said we were heating up the comm center.:sneaky::sneaky:

    I operated /MM on Kitty Hawk (CVA-63). The ham/MARS station was under the forward end of the angled deck; the port-most compartment on the ship. Right outside there was a catwalk that once served as access to a couple of verticals. The low-wings on the F-4s made relocating those antennas a hot priority. Antennas left....but the bases remained. A chunk of RG-8 ran from the shack out into the weather and to the best-located antenna base. From there we hung "about" 16 feet of stainless steel cable with about 20 pounds of scrap on the end to keep things fairly vertical (that SS cable used as aircraft tiedowns is NOT fun to work with).
    But we could work anything we could hear. When we joined 7th fleet we had to QRT until we headed back to stateside.
    Oh - that 16 feet of cable was actually a top-fed vertical, hanging down from the center of that antenna base. Worked just fine.

    There’s geeks, there’s nerds . . . then there is US Navy.
    My favorite tales of electronic derring-do are out of that fraternity.

    Beetle ,
    The favorite antenna was the "unicorn" antenna , mounted on the 11th deck with a 30 degree tilt forward over looking elevator 1 on forward part of flight deck, that thing screamed .

    Also like to use deck edge antennas but nothing came close to the "unicorn antenna".

    We heard the Hawkeye crew making mars call while they were on station.
    One of the JO got qualified as a MARS op then he was hooking his E2C crew up with phone calls home.
    Man I miss those old days.

    young sailors calling home find out they became fathers, some of the saddest ones were the ones when the chaplain knocked on the MARS station door with a crew member in tow, some of those calls were rough, not a dry eye in the shack.
