Portable Antenna Mount With Ground Plane

This is a compact portable antenna mount with a ground plane. It's a 1/8 inch aluminum plate, about 12 by 12 inches, with a male SO-239 connector in the center. The plate is held off the surface using four red insulator type standoffs. I use four ground radial wires cut for the frequency band of interest. When not in use they are coiled up and stored away. The coax is RG-58 about 12 feet long with a clip-on ferrite choke near the plate to help decouple the antenna from the cable. I used this on various occasions when traveling and staying in hotel rooms.
