    Hi all, I was not sure where to post this, either here or in the mobile ham section. If it is in the wrong section I apologize. The wife and I will be running the GOTA station again this year. In addition to the usual ground mounted multi-band vertical we normally erect I am thinking of adding some visual eye candy, especially for the youngsters who wander by. I have a little red steel “radio flyer” wagon that I would like to setup as an antenna farm. Can anyone suggest what models (and where I can get them) of ham sticks that can use an NMO mag mount? I am thinking maybe one for 10, 20 and 40 meters. What about mag mounts, any preference? I won’t mount the rig in the wagon, I’ll keep that on the table, but the antennas will be on the wagon. Thanks for any suggestions.

    An NMO mount is fine while stationary, but I wouldn't try to drive down the road with a hamstick attached to an NMO mount. The base will likely be insufficient to withstand the leverage of the antenna.

    I doubt if he could pull his Radio Flyer wagon fast enough for wind load to be a problem ...

    I don't know. When I was a kid we lived on a hill. I felt a pretty good wind in my face on the way down.

    Ham sticks use a 3/8"x24 female thread for their attachment. Same as a lot of CB antennas. You will need an adapter to go from the NMO to Hamstick. Here is what I found with a quick search on Amazon. I'm sure there are other options out there as well.

    Another option would be to skip the adapter and just install a 3/8x24 F mount directly to you wagon. One less point of potential loss and a small hole to drill.

    Once you have that installed, you can mount whatever Hamstick you want, from there it's up to you on what band you want to operate on.

    If it's just for show cut a piece of plywood (or OSB) to fit the bottom of the wagon and drill holes through the plywood and bolt them.

    Thanks, I thought about using a chasis punch to put a hole in the wagon but then I thought that the wiring under the bed of the wagon might snag when being moved. My tinking was that the mag mount would keep all the wiring up top and safe but maybe I should rethink that.

    I did that a few times, too. Until the one time a car on a cross-street nearly hit me, and my mom saw it.

    Not much cable and connector loss to worry about at those frequencies.
    The lack of any significant metal for a ground and that the antenna (already a huge compromise) sits about 8 inches off the ground will be the big signal killer.

    Plastic wire ties solve that problem.

    The "industrial grade" zip ties, mind you, not the cheap ones.
